EGU General Assembly 2022

The EGU General Assembly is Europe’s largest annual conference on geosciences. The last two years the meeting was organised as a virtual meeting. This year, the EGU will be hybrid, both in-person in Vienna and online. All presentations will be held as short orals. Due to remaining hygiene restrictions, there will be no poster sessions.

TiPACCs related research is again abundant during this EGU. A selection of interesting sessions and presentations can be found below, ordered chronologically.
