The guidelines for authors can be found on the EGU General Assembly Guidelines page and are reproduced below.
Oral presentations are organized in oral sessions scheduled in specific lecture rooms given in the programme together with the time of presentation of each contribution including discussion and change over. The oral sessions are scheduled in four time blocks per day, each time block with 90 minutes. Please note that the duration given to your oral presentation includes 3 min. for questions and discussion, e.g. a 15 min. talk should be 12 min. actual presentation + 3 min. discussion.
The oral presentations are not organized centrally. Therefore, the authors are kindly asked to upload their presentations directly in the respective lecture room within 30 minutes preceding the actual time block of the session starts. A lecture room assistant will be available for any help.
It is strictly prohibited to take photos and/or copies from notebooks of any scientific material without the expressed permission by the authors.
