The EGU General Assembly in 2024 will combine the best of long-established, traditional presentation and networking formats, while drawing on new concepts to support hybridization, and improving accessibility and inclusion for all of our participants. EGU24 will feature oral presentations, poster sessions, and the established PICO format for presenters on-site in Vienna as well as those presenting remotely.

Oral presentations

All EGU24 oral sessions will be available for participants in a hybrid format (virtual and on-site). The hybrid function of the oral presentations will be delivered with Zoom meetings using lectern cameras and microphones. Oral sessions will be scheduled for a specific day and time block(s) in a lecture room in Vienna (simultaneously on Zoom), following the schedule below:

EGU24 Schedule

• Oral presentation sessions will be composed of 10 minute presentation slots (including questions), allowing for flexibility in organizing the session.
• Authors of oral presentations are strongly recommended to upload supplementary materials for asynchronous discussion and possible revision during a 2-month period, from 25 March 2024 to 31 May 2024. During this commenting and discussion period, only registered attendees are granted access. Afterwards, supplementary materials are opened to the public through EGUsphere and distributed following the CC-BY License.
• A minimum of 24 hours prior to the oral session's start, authors are obliged to upload their presentation file containing the slides. This file is then distributed to the respective lecture room, and is linked on the session page during the session’s scheduled time block(s).
• The scheduled oral sessions will proceed as follows:
• On-site authors use the lectern and its microphone to give their presentation. They will be able to forward their own slides provided in the presentation upload. The presentation runs on the lecture room computer connected to a projector and shared simultaneously in the Zoom meeting.
• Virtual authors will join the session through the Zoom meeting. Once their presentation begins they will unmute themselves in order to speak to the on-site and virtual attendees. Their previously uploaded presentation files will be shared by the on-site conference assistant on the lecture room computer. The conference assistant in the room on-site will forward the slides for the virtual speaker. The virtual speaker's camera feed is shown to the on-site attendees on the projector.
• On-site attendees engage with all presentations on the screen inside the lecture room. They can propose questions to the speaker (either virtual or on-site) moderated by a chairperson, using the in-room microphone
• Virtual attendees engage with all presentations using the Zoom meeting operated from the lecture room computer. Virtual attendees will have a side-by-side view of either the on-site or virtual presenter and the presentation slides. They can ask questions through the Zoom chat and a session chairperson will moderate and repeat questions, to be answered by on-site or virtual authors.

Poster presentations

All EGU24 poster sessions will be available for participants in a hybrid format (virtual and on-site). They will be scheduled on a specific day and time block(s), following the schedule below:

EGU24 Poster schedule

• The posters in every session are divided into those being presented on-site in Vienna as well as the ones being virtually presented, using a specially designed platform on Gather.town. Authors of on-site posters are assigned a poster board number in a poster hall in Vienna, while authors of virtual posters are assigned a poster board number in a corresponding virtual poster hall on Gather.town.
• In order to support both formats of presentation, authors of poster presentations are strongly recommended to upload supplementary materials for asynchronous discussion and possible revision during a 2-month period from 25 March 2024 to 31 May 2024. During this commenting and discussion period, only registered attendees are granted access. Afterwards, supplementary materials are opened to the public through EGUsphere and distributed following the CC-BY License. The supplementary material of a poster presentation does not have to be the poster layout itself, it can also be a PowerPoint presentation or a recorded video.
• A minimum of 24 hours prior to the poster session's start, authors are obliged to upload their actual poster as a presentation file containing the poster file. This file is then linked on the day of the poster session alongside the abstract on the session's web page. These live presentation poster files are only available on the day of the session (8:30–12:30 or 14:00–18:00 for on-site poster authors, and 8:30–18:00 for virtual poster authors), while the corresponding supplementary materials are available for a 2-month period for commenting and discussion.
• The scheduled poster sessions will proceed as follows:
  • On-site authors set up their poster in the poster hall in Vienna, at the assigned poster board number during their respective display time (time block 1 or 3) or at the beginning of their attendance time of the scheduled day of the poster session. During their scheduled attendance time (time block 2 or 4), on-site presenters stand next to their poster replying to questions from on-site attendees. Presenters are welcome to continue the discussion beyond their scheduled attendance time, but should be mindful to take down their poster by 13:30 for AM sessions or 19:00 for PM sessions when clean-up commences. Any posters left hanging at this stage will be discarded by the conference assistants. Following the scheduled on-site live poster presentations, authors should check their supplementary materials for questions from virtual attendees, which can only be posted as comments to the supplementary materials and discussed there.
  • Virtual authors will not set anything up themselves in Gather.town. Their poster board number will be displayed in Gather.town, linking to the previously uploaded live presentation poster file, which will also be visible on the session's web page. During time block 3 of the scheduled day, they 'stand' next to their poster board on Gather.town, replying to questions from virtual attendees. On-site attendees can also interact with virtual authors by entering Gather.town, through the virtual poster hubs set-up on-site in Vienna, as well as using the supplementary materials to leave comments which can be answered at a later time.
  • On-site attendees visit on-site posters in the on-site poster hall in Vienna.Virtual poster interaction can take place using Gather.town in one of two ways: by logging into Gather.town directly, or through an on-site virtual poster hub. During time block 3, the PICO spots of each corresponding poster hall (i.e. X2 on-site is vX2 in the Gather.town space) will transform into a virtual poster hub. A conference assistant will navigate the virtual poster hall, visiting the virtual posters, to be displayed on the large screen. On-site attendees can pose questions using the microphones provided, moderated by an on-site chairperson. They may also use the PICO viewing screens to browse through the uploaded live presentation files of the sessions taking place in the corresponding virtual poster hall.In addition, previously uploaded presentation poster files of both on-site or virtual posters can be accessed through the session's web page on the day of the poster session. Questions of on-site attendees are asked to the presenting authors during the scheduled time block, either face to face on-site or virtually by logging in through Gather.town.
  • Virtual attendees visit virtual posters during time block 3 using Gather.town and meet virtual presenting authors there for questions during the scheduled time block. In addition, previously uploaded presentation poster files of both on-site or virtual posters can be accessed through the session's web page, on the day of the poster session. Questions to on-site authors from virtual attendees can only be posted as comments to the supplementary materials and the authors will be able to respond there.

PICO presentations

All EGU24 PICO sessions will be available for participants in a hybrid format (virtual and on-site). They will be scheduled on a specific day during time blocks 1, 2, and 4 at a PICO spot in Vienna, following the schedule below:

EGU24 Schedule

• The PICO spot provides a combination of a stage and audience area for a 2-minute summary of abstract introductions, together with a number of PICO screens for detailed presentation of slides or other materials and discussions afterwards. PICO spots will also be provided with a Zoom meeting connection to allow virtual presentation and attendance during the 2-minute introductory talks, followed by discussion with virtual authors.
• The abstracts of a PICO session are scheduled for a specific time and day. In addition, on-site authors are assigned a PICO screen number on-site in Vienna.
• Authors of PICO presentations are strongly recommended to upload supplementary materials for asynchronous discussion and possible revision during a 2-month period from 25 March 2024 to 31 May 2024. During this period of commenting and discussion, only registered attendees are granted access. Afterwards, supplementary materials are opened to the public through EGUsphere and distributed following the CC-BY License. The supplementary material of a PICO presentation can be the same as the presentation file, but does not have to be. Authors can choose if they wish to provide further information or even a recorded video.
• A minimum of 24 hours prior to the PICO session's start, authors are obliged to upload their actual live PICO presentation file containing the slides for the 2-minute introductory abstract summary presentation, as well as the longer, detailed presentation. This full file is linked during the PICO session's time block alongside the abstract on the session's web page. Presentation PICO files are only available during that time period, while the corresponding supplementary materials are available before and after the actual run of the PICO session.
• The scheduled PICO sessions will proceed as follows:
  • On-site authors use the lectern at the PICO spot to present their previously uploaded live PICO presentation file. On-site presenters will be able to move their own slides forward. This projection at the spot's screen will be shared simultaneously in the Zoom meeting for virtual attendees. After all PICO presentations have been pitched, the on-site authors move to their assigned PICO viewing screen (according to their assigned number) at the PICO spot. The presentation file is automatically opened at the PICO viewing screen. On-site attendees will now visit to ask questions and discuss the longer format slides. Following the scheduled on-site live PICO presentations, authors should check their supplementary materials for questions from virtual attendees, which can only be posted as comments to the supplementary materials and discussed there.
  • Virtual authors will use the provided Zoom meeting to give their 2-minute introductory presentation. The previously uploaded presentation files will be controlled by the conference assistant on-site at the PICO spot in Vienna. The presenters will unmute themselves to be heard within Zoom by virtual attendees, as well as by the on-site attendees in Vienna. After all PICO presentations have been pitched, the virtual authors will remain on Zoom for a moderated discussion, accepting questions from the on-site and virtual audience members. Further discussion can take place in the comments of the uploaded supplementary materials, which can be answered at a later time.
  • On-site attendees will visit the PICO spot's stage area first, to follow the 2-minute introductory talks. Afterwards, they move on to the PICO viewing screens according to their interest. They can engage with the presentation files as these files automatically open on the assigned screens and ask questions to the on-site author directly. Alternatively, attendees may stay in the PICO stage area to pose questions to the virtual authors using a microphone, moderated by the session chairperson. Further discussion or questions can take place on the uploaded supplementary materials, which can be answered at a later time.
  • Virtual attendees engage with all 2-minute introductory presentations using the Zoom meeting operated from the PICO spot computer. Virtual attendees will have a side-by-side view of either on-site or virtual presenters and the presentation slides. Following the 2-minute presentations, virtual attendees can stay in the Zoom meeting to follow the discussion and ask questions to the virtual authors, which is moderated by a chairperson. Virtual attendees can only ask questions to on-site authors by posting a comment on their supplementary materials for discussion.
