ACC cross-cutting activity The « Paris bureau »

H. Le Treut

Brief elements of context

• The « Paris bureau »: legacy, from SPARC, then « COPES bureau », then home of « ACC crosscutting activities » (but also general support to general WCRP activities)

- funding by CNRS/CNES - a dedicated person: Catherine Michaut

• An ACC crosscut ?

Historically two roles: identify gaps advertize WCRP activity

Two focused objectives:

1. Hosting/organizing workshops on key gaps concerning ACC: key processes, interface between core

projects, interface between WCRP and other partners

2. Providing information concerning WCRP implications in ACC studies (Web pages hosted by Catherine Michaut)
