Purpose | This NDVI product is generated by the POSTEL Service Center, using the spectral directional albedos at 0.6µm and 0.8µm derived from the SEVIRI/MSG data processed by the LSA SAF operational node at the Institute of Meteorology of Portugal. The NDVI is in the physical range [-0.2, 1].
Projection: The original LSA SAF products are presented in the satellite MSG projection. They have been put in the geographical lat/lon projection (plate-carrée) with a grid step equal to 0.05°. The West_Africa area, which covers the zone from 24.98° West to 24.98° East, and from 4.98° South to 19.98° North, have been extracted from the 0.05° resolution grid. The pixels of the grids are located by the coordinates of their center. Product Quality: The NDVI over West Africa display a line of no-data pixel for 0° of latitude. This is an impact of a problem concerning the cloud mask in the original LSA SAF algorithm. This effect has been corrected from November 1st, 2005. | ||
