CliSAP B1 and adjoined scientists meet on a regularly basis. Aim of the meetings is to discuss the results achieved and focus on the common tasks in the next years.
Monday 28. October 2013 - 13:00-17:30
ZMAW 022/023, Bundesstraße 53
We cordially invite you to the first science workshop of the CliSAP Research Topic B1 Arctic and Permafrost. The aim of the workshop is to get an overview of ongoing and planned work related to the Arctic climate system (not necessarily funded through CliSAP). Moreover, we'd like to identify and survey the overarching key science questions which need further coordination.
