General Assembly 5

27 to 29 April 2020 Online
  1. To communicate results from analysis of PRIMAVERA and HighResMIP simulations within and outside the project
  2. To see how these results have been useful for users of climate information
  3. To summarise the achievements and legacy of PRIMAVERA and future plans

Agenda for the online PRIMAVERA General Assembly GA5

The agenda is online here. Please see also the Slack channel for details of the zoom meeting links, posters, discussion channels and other information (registration to slack may be required).

We enjoyed a virtual meal together, with some favourite national dishes being cooked by colleagues from other countries.

We also had an excellent quiz which was both excellent fun and had us all learning about aspects of the project.


All timings UK British Summer Time (BST) - +1 hour from GMT
