As part of the climate change research, data from the SPOT/VEGETATION instrument are systematically corrected for period 1998-2004 and provided in this archive. The VGT archive contains observations acquired by the VEGETATION sensors 1 and 2 onboard SPOT 4 and 5 satellites. Initial data type 10-day S10 composites provided by the Centre National d'Etudes Spatiales (CNES) and pre-processed at the Flemish Institute for Technological Research (VITO) in Belgium in full resolution (1km) were re-projected into standard Lambert conformal conic map projection and further corrected for bi-directional Reflectance Distribution Function (BRDF) effect and cloud contamination. Growing seasons 1998-2004 are presented with twenty 10-day composites from April 11, to October 31. Each composite contains four at-surface apparent reflectance bands: blue (0.43-0.47 mm), red (0.61-0.68 mm), near infrared (0.78-0.89 mm), and shortwave infrared (1.58-1.75mm) and two data layers containing normalized difference vegetation index (NDVI) and Cloud mask. The 10-day composite data were reprocessed following Canada Centre for Remote Sensing (CCRS) post-seasonal correction. This improved product is used in land cover and climate change studies to generate various high-level products such as Fraction of Photosynthetically Active Radiation (FPAR) and Leaf Area Index (LAI).
