General presentation of the Products

The OSI SAF commitment in terms of products in the framework of the current phase, the CDOP, is detailed in the Product Requirement Document (PRD), available on this site.
Once products are set into (pre-)operations their specifications are detailed in the Product Specification Document, available on this site.
The Product Status categories are defined here.

    Parameters

    The parameters retrieved at the sea surface are :

    Areas

    The areas currently used are defined as following :

    Satellites

    The OSI SAF products are using in priority the European Meteorological satellites METEOSAT and MetOp and also several american satellites operated by NOAA , DMSP and NASA.
    The use of NPP is envisaged around 2012.

    Accessibility

    The products are accessible in near-real time :
    The products are archived in the production centers and available on the corresponding FTP servers or on request.
    Between 2008 and 2010 the archiving is also being implemented at the UMARF, EUMETSAT Unified Archive.
