EEA – Copenhague 3 18 - 19 May 2006 SeaWiFS: JRC-FAPAR datasets;10/1998-12/2004 at global scale 2 km MERIS: ESA Level 2 products; 06/2002-end of mission at 1.2 km (Full resolution at 300 m not operational) Level 3, i.e. time composite products, are produced at JRC through the Grid on demand service (ESRIN) with JRC codes. MODIS (2000-end of mission) : JRC-FAPAR algorithm (both Level 2 and Level 3) has been developed at 1 km/500 m/250 m but there is no operational processing.

6. EEA – Copenhague 6 18 - 19 May 2006 MERIS: ESA Level 2 products at full resolution at 300 m are not yet operationally produced by ESA. Remote sensing data at higher resolution Once installed, FAPAR-processor is automatically detected by VISAT (the BEAM main application, see http://www.brockmann-consult.de/ ). The FAPAR processor appears in the Tools menu of the VISAT application. The FAPAR product created can be saved in several formats (HDF5, BEAM-DIMAP).
