CNES, INRAE Avignon and the CREAF in Barcelona have joint force in this action realized within Theia Vegetation Biophysics Variable SEC.
Two AVHRR products are available to document a time series of vegetation variables (leaf area index, fraction of PAR absorbed and vegetation cover) for the 1981-2019:
- GEOV2-AVHRR is a global map of vegetation biophysical variables (FAPAR, LAI and FCOVER) calculated every ten days from AVHRR LTDR data.
- GEOV2 Global Change Monitoring product (GEOV2-GCM) is a global map of vegetation biophysical variables (FAPAR, LAI and FCOVER) calculated every ten days since 1981 at 0.5º resolution after resampling the 0.05º GEOV2-AVHRR products.
Both products are computed using data from the AVHRR instrument flown on board various NOAA platforms.
