Summary

The meeting followed the proposed agenda and the attendees did not suggest any additional item for the discussion.

The functional specification for the EUMETSAT bias plotting application was accepted without any modification. During the discussion on the global attributes and variables to support the plotting application slight differences were identified by the participants so the final decision was postponed until further discussion.

Action Ref.	Description	Assigned to	Due date	State
WM20120619_01	Prepare a proposal on the set of netCDF global attributes and variables to support conversion to/from brightness temperature/radiance and submit to the GPRCs for final approval.	FangfangYu, AleksandarJelenak	03 Jul 2012	closed	edit

WM20120619_02	EUMETSAT to make the bias plotting application available to other GPRCs for testing. The application is still in the development phase.	PeterMiu		closed	edit

The GEO-LEO-IR netCDF template was accepted without any additions. On the common values of the id global attribute all attendees adopted the proposal to use the file name. This makes the filename global attribute obsolete and will be removed from the template.

WM20120619_03	Update the netCDF GEO-LEO-IR template by removing the filename global attribute and specify that file names are values of the id global attribute.	AleksandarJelenak	19 Jun 2012	closed	edit

Regarding the THREDDS data server configuration and the need to accommodate the recently introduced local data subcategories, the agreement was to structure the display of the available datasets in the following manner:

WM20120619_04	Provide THREDDS configuration files that incorporate the new display structure with local data subcategories (i.e. algorithm types).	AleksandarJelenak	31 Jul 2012	closed	edit

On the final item on agenda, the Datacasting web feed protocol, all the attendees agreed that it could be useful service to have, not only for users but even for the GSICS community. Further specification how the protocol should be implemented on the GSICS data servers is to follow.

WM20120619_05	Provide Datacasting implementation guideline document for further discussion.	AleksandarJelenak		open	edit
