Breakout sessions
13:30 - 16:00 CET / 11:30 - 14:00 UTC
Breakout 1: GRUAN cooperative approach to access resource in support of network operations
Moderator: Peter Thorne
The breakout session will discuss the GRUAN proposal for the EUMETSAT validation campaign of MWI/ICI as well as other opportunities for funding different activities or subgroups of stations. The discussion aims also at identifying what are the real funding needs of the network and how to establish a cooperative approach to access funding.
Breakout 2: Design of a quality assurance framework and quality flagging system for GDPs
Moderator: Tom Gardiner
Upon discussion and input received during FORUM 1 and other discussions, the session aims at writing the draft of a document where the skeleton of the quality-assurance framework and quality flagging system for GDPs will be described. This initial document shall serve as the basis for a more structured document to submit to the WG-GRUAN for discussion and, after approval, to include in the updated GRUAN guide.
