EGU 2022: Back in person

Posted on by

EGU 2022 is done and as always it was a great experience. As the first partly in person meeting in three years, it was great to see colleagues and friends again after all that has kept us apart in that time. Originally planned in April it was shifted for a few weeks as it was determined not plausible to have the conference under the COVID situation earlier. Sure, that might have kept some away, but was certainly the best decision under the circumstances.

The conference

The conference started on Monday with the typical technical issues, some where not solved until the end of the week (like accessibility issues of the listings during a live session on site). For me it was more a day of visiting different sessions on various interest. Tuesday was dominated by the North Atlantic session with many interesting talks. On Wednesday I had my calm day and focused more on meeting people rather than spending the day in sessions.

The serious part of the conference for me started on Thursday. We had the third edition of our S2D-Session, and with it the first one with in person attendance. It went quite well. We had a medal lecture at the start and we even managed to get a small discussion started.

Friday was then time to give my own talk on challenges within climate models. The talk went alright and so the rest of the day was a typical EGU Friday. Meeting people, follow some last sessions and saying good-bye to Vienna.

Does the format work

Due to the situation the format was changed to shorter presentations only and with it the poster session canceled. Instead of the traditional 12+3 format the speaking time was reduced towards 5+1 or 6+1. Many conveners used their freedom to include discussion time into the session and hat a bit more to do to manage the hybrid format not only in the room, but also virtually.

While everybody was happy to have the in person experience again, there were quite a bit of discussions on the hallway that the format was not ideal. Everyone accepted that it was the best that could be done in the situation, but it was clear that many hoped to get back to a more traditional format. Hybrid will likely stay, which is good, as it offers more accessibility and probably will also limit a bit the overcrowding in the centre.

Main point mentioned in many conversations was the desire to get the poster sessions back. EGU was always special in the sense of a combined late evening session, used for interactions, meet ups and finding dinner groups (beside discussing science). After the failed experiment to divide the session over the day in the last editions before COVID the canceling of it this year lead to a huge hole in the conference experience. It let to much less interchange between fields and so most people met those who they had planned to meet anyway (no wonder after not seeing some colleagues for three years). Certainly it is to be hoped that we get the old format back when COVID allows. How to make that possible in a hybrid format will be a huge challenge.

Second topic was the shortness of the talks. I heard many, especially first time visitors at an in-person conference, that felt that they get not enough out of it. Instead of increasing the accessibility due to an all talk format, it massively reduced it. 5 or 6 minutes are not enough to get into a topic, especially for non-experts of a field and so you loose with 15 talks in 2 hours track on what happened in which talk. Also having 5 talking sessions on a day is too exhausting, especially when medal talks follow in the evening. It also almost killed completely any question or discussion, as the short time did not allow people to collect their thoughts to ask a meaningful one.

But of course there are things, which might be improvable without huge changes. One would be the option to show virtual presenters a timer, including the option to warn them that their time will be up. The necessity for conveners to talk into the presentation and with that stopping the flow of it, was a huge problem. The most used word during the days was „next“ to advise a slide change by the assistant (who by the way did as always an amazing job). Also many on-side presenters chose to use the assistants for slide changes, as the equipment in the rooms was for many unintuitive and inadequate. How to solve pointing onto the slides, while making it possible to be followed by the virtual community will also a big topic for the future. And as always, it would be possible to show in the online system all sessions at a given time, independent of the division they belong to.

But yes, beside all the criticism there were also remarkable positive points. People where happy for the coffee breaks (even when too short) and all the free tea and coffee. Also the water points to refill bottles were great. To place the exhibitors into the tent instead of the lobby might have given them less footfall, but it really opened space for chats. Having the A-hall, unused by the usual poster session, as a meeting point was awesome. That enabled everybody even with the lack of two poster floors to meet in a relaxed environment.

All in all it was great to be back in Vienna and we hope it is there to stay.

vEGU2021: A “zoom” into science

Posted on by

Another EGU in online only mode and things have changed since last year. It started with technical chaos but after this got under control it was a really nice and enjoyable conference experience.

A week before

EGU is traditionally one week long, but this time it got extended for another week. The week focused on medal lectures and some networking events, but as those where hard to see, it was for most obviously just about the household names giving an interesting talk. Those talks were on Zoom, which allowed a simple following for most. For myself and many others it was still the week to prepare the contributions. The displays of last year got back, but were extended by a single slide for a 2 minute presentation. Communicating about this worked not really ideal, so there were still some questions around what acutally had to be prepared.

The “real” first day

We had the honor to convene our session on seasonal to decadal predictions in the morning of the “real” first day.

EGU had implemented a new environment compared to last year, which theoretically took care of some issues bugging last years edition. It started alright, but soon people had trouble to get onto the server (nothing unusual at EGU, that’s what we know from every edition). But as some speakers had audio troubles and then the promised breakout-chats after the initial comments did not show up it was quite a improvised discussion session. We implemented more or less a system we had used last year in the chat-only conference, but beside the chaos it was sad, that not everyone got the input on their contribution they deserved. But still, it worked rather well under the circumstances.

The sessions later that day were even more catastrophic from the technical side of things and so the technical system was changed to Zoom only. From then on it worked quite well, as most scientists are used to Zoom after a year of pandemic.

Relaxing in the middle

As a scientist with quite interdisciplinary interest, I always find something, which I like to watch. But this year I had the impression it was even more condensed. Anyway, a digital conferences has its advantages. You can stream the talks onto your TV, enjoy your couch and when the show is over you get to your desk to have some chats in the breakout rooms. In the evenings some networking events happened via Gather.town. It offered some options for meetings, which is the part which sufferes the most in digital conferences.

Final day

Friday was the day of my own little presentation and a lot of other talks I liked to see (unfortunately all at the same time).

My talk went quite alright, having a short talk does not require much creativity. There is not a lengthy introduction, everything is brought into short soundbites and it is effectively just an advert to lure people into the breakout session. Had a few discussions afterwards and enjoyed otherwise the rest of the meeting. In the evening was a closing party over Gather.town, which was a bit better than the Zoom one a year before, but still not optimal.

Do digital conferences now work?

Many said they preferred this year over the last edition. beside from the technical chaos on Monday it was quite enjoyable. It is still far away from the personal experience in Vienna, which I look really forward to in the upcoming years. It was possible to find and talk to people and former colleagues, setting up new projects and see what others do. Some liked the 2 minute presentations, I think they are not ideal.

Because the main struggle of this zoom-like conference is taht again Early Career Scientists py the prive. It is tough for them to get into a 2 minute ad-talk, stripped of all introductions and motivations. When you have seen the field beforehand in the last years, you know usually what they are talking about, but for those getting new into science it can be a quite steep demotivating learning curve. Also they do not get much exposure in the breakout-rooms cause established scientists use them for larger chats among themselves and drawing with this the attention away. The separation into talks and posters at the usual personal conferences has its advantages, which are often forgotten. But as also former editions of the EGU had developed away from ECR-friendliness, it is nothing surprising. The biggest challenge of a future EGU, may it be hybrid or online, will be to advance the experience of young scientists.

Final words

All in all it was a great conference. I like being at the EGU, it is still the go-to-conference every year, because of its interdisciplinary opportunities. After day one it was alright, and it went rather smoothly. Let’s hope that next year will have again some form of real Vienna in it, as I miss to meet friends and other scientists in person. See you next year, wherever it will be.

An honest comment

Posted on by

The party is over, EGU 2019 is history. Over the days I have written some impressions I got from the conference, but sticked mostly to the positive points (Day 1, 2, 3, 4, 5). As always, the EGU itself, the opportunities it offers to talk to all kind of scientists and listen to their advancements was amazing. But compared to the last years the organizers have implemented several changes to the program, on which I would like to address a few honest comments. I am very aware that there are many people in the background who do a hell of a job to make this conference possible and they face the impossible task to make everybody happy and the challenge that every year more and more scientists want to attend the conference.

The topics I want to address in this post are the following

  • increase from 6 to 7 talks per session
  • limit to one contribution per scientists (instead of two)
  • poster sessions in parallel to talks
  • networking session instead of poster session in the evening
  • general comments

Most of these topics came up in many many conversations during the days with other scientists, people are complaining every year (usually about the drinks and the rooms for certain sessions), but this year there were constant discussions about all sorts of complaints.

Number of talks per session

In order to have enough time for the in parallel running poster sessions the number of talks was increased from 6 to 7 per session. A reason given was that more scientists want to have a talk rather than a poster and therefore there should be more space for talks. I personally have expected a worse impact by this change. Yes, surely, after six talks you are tired and do not listen anymore to the last one as you should, but as many do not follow the whole session anyway (see poster parallel to talks below), it seems to work. What I find more problematic is the notion that only because scientists prefer talks they should given more of them. First, this devalues posters and second, talks are up to now seen as something like an award for a good abstract and an interesting topic. Devaluing posters and talks at the same time is certainly not good, but as we have to see it as a business decision, it is acceptable. Especially as it has a reason behind it (more time for posters).

Limit for contributions

When I found out about this change I was honestly deeply worried. I have made the argument in the past that this change will heavily impact early career researchers.

The argument for this is two fold. On the one side the big shots will get a talk. Generally EGU is good in promoting young scientists to get talks at their conference. And with more talks available, it is hoped that the opportunities are not diminished for the ECR’s. I have no overview whether this has worked, but I give the benefit of the doubt. The other side is potentially much more damaging. In theory most senior scientists will now have only one abstract and most of them will end up in talks (I neglect at this points that most senior scientist are able to put fake first authors at the first place of the author list to have as many contributions as they want). That means, they will not have a poster where they are obliged to fulfill their attendance time. And it is the poster sessions where ECR’s have a chance to get in contact with the senior scientists, might it be to make their names known or make important steps for their career. By risking to loose these opportunities (see someone you are interested in a talk and then go to their poster to talk with them), ECR’s are in risk of loosing chances to progress. I understand that there are now too many scientists to give everybody a second contribution, but I am not really convinced by this argument. Because when you walked through the poster halls, many many lines in of poster boards where empty. So there is space for more posters. Might there be ways of change? Sure, but they might all be more complicate to implement (allow two contributions, with a first and a second, but the second is not guaranteed to be allowed to get through… but as many author lists are cheated it will be hard to implement as scientists will find ways around it).

Empty poster boards over the day

Poster sessions in parallel to talks

The biggest change was to put posters in parallel to talks. It is not uncommon to do this at conferences, AGU is famous for that. Nevertheless, I do not think that this is a good decision. There are massive consequences for the conference, not only for the posters, but for the talks as well. Compared to my last experiences at EGU I got the impression that more scientists leave the talks in between. This leads to disturbances, especially in the small rooms. As they are overfilled anyway, people leaving are ending in pushing and and asking for letting them through. Also posters are devalued by this. I was surprised that in the poster session I attended there was still proper crowd (and that at the end of the conferences), but in the end you have now to choose: see the headline science in a talk or much more of potentially non-headline stuff in a poster session. It might work when you are a disciplinary scientists (as I have written before, EGU is not really prepared for interdisciplinary visitors) as ideally there are just a few sessions you really care about and those are all coordinated that the poster sessions do not overlap the talk sessions. But honestly, this hardly ever is the case. As a consequence I have certainly missed out of many interesting discussions at the posters this year as well as many talks (usually ECR talks), which I had to skip because I still wanted to have the chance to see scientists at their posters.

The networking session

Networking is important. Anyway, the networking session was introduced to full the space for the poster session. And in my opinion, the introduction of the final hour in the evening has completely failed. At the first day you saw quite a lot of people in the poster halls talking and drinking, the typical catch up at the start of a conference. But the following day a huge amount of scientists used this hour to make an early end to the conference day and went to town for food. So basically the conference was shorten every day by an hour. I also missed the walk through the poster halls at the end of the day. Have a drink, go to sessions you potentially wouldn’t have had walked in on purpose and having nice chats with young and senior scientists. That is for myself (and many others I spoke) the most important part of a conference. This is gone at the EGU. Most scientists take down their poster either directly after their poster session in the morning/afternoon or at the beginning of the networking session. There is hardly anybody at their posters anymore and especially those you want to talk about are gone. In my opinion this has heavily damaged the usefulness of the conference. So at least make the network session another attendance time for the poster. Having one in the morning/afternoon and then another in the evening for everybody who preferred talks over the day would be proper way to minimize the impact.

General comments

Yes, complaints at EGU are the usual, but having this many heard over the days in close to all conversation I had is not a good sign. And we are now not talking about the little thinks like drinks (you can never make that right) or room choices (they are always too busy in the small rooms and to empty in the big ones). And yes, there are some complaints I can fully understand on the minor topics (offering springs to not to use so many plastic bottles, but giving out the drinks in the evening in plastic bottles? Really?!) The topics mentioned above are much more damaging for the EGU and the experience the scientists take from it. It leads to devaluing posters, disturbances in the talks sessions, ECR’s only confronted with people who care about their topic and hardly anymore a wider audience, even more the feeling you have missed important research and opportunities, and the impression that that what many people valued so highly at the EGU is gone. While I do not expect that there will be a roll back of the changes for next year, there will be a bigger topic coming up for the future of the EGU, which I heard in so many conversations: Is Vienna still the right place for the EGU? We all love Vienna, not too expensive, a nice conference centre, good opportunities to live, eat and socialize during the conference. Nevertheless, EGU has outgrown the conference centre. The queues at the small rooms get longer and longer, many do not get in and then look for a second choice. In some sessions the number of people in the room where double the number of seats available. Together with the changes made this year and the consequences that even more scientists want to switch between sessions and posters, I do not see how Vienna can be the long-term choice of the EGU anymore. The alternative would be to actively limit the number of scientists attending, e.g. by rejecting abstracts. Honestly, nobody wants that, but the changes implemented this year haven’t made the conference experience better.

International Conference on S2S2D

Posted on by

Last week NCAR in Boulder (Colorado) hosted the second edition of the International Conference on Subseasonal to Decadal prediction. It covered the climate prediction from a few weeks up to a few years and hosted with around 350 scientists a good representation of the community in this field. During most of the days the conferences was split into a subseasonal to seasonal (S2S) and a seasonal to decadal (S2D) session.

The International Conference on S2S2D poster

I personally visited only the S2D part, as my current work focuses on this topic. The first day looked into the mechanisms of predictability and the typical candidates, like ocean, soil moisture and stratosphere, were discussed. The second day shifted then more to the modelling of these phenomena. The weather services presented their new prediction systems and new approaches to modelling were discussed. As a third topic covered the handling of the predictions. It looked at calibration and other technique to make the prediction really useful. This lead to the fourth topic, which discussed the decision-making process basing on the prediction. Here, the applications were the main focus points and many different phenomena and their predictability were shown. Topic number five looked at the statistical verification. It presented new approaches to access the skill of the models. The final session of the S2D session looked at the frontiers of earth system prediction and therein especially at the handling  of carbon within the models. Afterwards in a combined session of both parts many different aspects on the future of research in this field were brought up. Among others the topics of temporal dependence of forecast skill and the so-called ‘signal to noise paradox’ lead to a lively discussion.

My personal contributions were threefold. I showed on a poster in the first session how the Summer NAO can be predicted using ensemble sub-sampling. In the second session I presented a poster on the view that sub-sampling can be viewed as a post processing procedure and can so explain why it works. The  talk in the fifth session then covered  the  2D categorical EMD score.

All in all it was a great conference, with  many interesting discussions and a great overview over this interesting field. Certainly many impulses will come from this and will give not only my own research a  new push.

EGU 2017: Final day

Posted on by

It’s over. Five days of interesting talks, posters and discussions are finally done and the EGU 2017 has reached its end. The final day was for me the only one where I had some contributions on my own and so it was a busy one.

After I have hung up my posters (yes, I had two to cover today), I went to a palaeo-session and listened to many talks about ice sheet modelling and data collection in Antarctica. After lunch I had the session in which I had to give my talk on the seasonal prediction of the SNAO.

The session lasted two slots long and the final talk on the supermodel reminded me of the SIRF I applied in my last paper. Interesting to see it applied to a full-scale model. Finally the day ended with the poster session, but this time I had my two posters and a lot of talking to do (and yeah, EGU finally retweeted a tweet of mine ;)).

So all in all it was a great conference. I enjoyed Vienna once again, met many interesting people and saw so many interesting talks and poster that I look forward to the next time. The hottest topic in my view was the warning of the observationalist that there is really a problem building up in Antarctica. I saw two medal lectures on this topic and the claim that models currently underestimate the potential sea level rise are quite worrisome. The thing I was not so happy about was the provisional building in front of the main building as it covered the meeting place and changed the atmosphere of the breaks. But to answer the question of my first post from this years EGU, it seemed as the resources for beers and wine for the poster sessions were alright, as the complaints were relatively quite during the days. At the end it is time for me to say goodbye from Vienna (I will do that with another day here) and taking all the new ideas home and hopefully having the time and opportunity to make something out of them.
