Discussions :

1) Met OCean WMS Best Practices draft on Time handling for climatological and climate change data

The previous teleconference concluded that we should not overload the TIME dimension with a specific complex semantic. So the two remaining solutions are to put the informations on temporal informaitons attached to the products into the name of the layer or into specific DIMENSIONS. The first option (put this info into the name of the layer ) was rejected for forecasting data because of the amount of layers this solutions would have supposed. Are we in the same situation there? Meteo-France for instance is working on portal offering the outputs from :3 laboratories, 3 expériments, around 10 models, 15 parameters, 4 CO2 scenarios, 2 to 4 time horizons, and 10 integration periods =>~162000 layers?

UCAR has implemented a server providing anomalies over a period compared to a reference period covering 1980 to 1999 with the minimum temporal info into the name of the layer. (I.E. no reference to the reference period) This compromise is based on the consideration that the scientific have plenty of portals and means to get the data and other raw outputs. The maps provided by a WMS server will satisfy rather general users that don't require many, detailed informations. There is no feedback at the moment. A connected question is : How to advertise a broad and fuzzy community of the availability of such services?

The synthesis of the interoperability day organised by the EGOWS community will be presented in Boulder and is available on the twiki at : http://external.opengis.org/twiki_public/pub/MetOceanDWG/MetocWMS_WMS_IE_Retex/Final_synthesis_Egows_2011_interoperability_testings.ppt

2) Next telco

There will not be teleconference for the two next weeks in order to prepare the Boulder TC. The Boulder sessions will benefit from remote connections.
