Abstract:
The Global Inventory Modeling and Mapping Studies (GIMMS) data set is a global
measure of normalized difference vegetation index (NDVI) covering a 22-year
period. The GIMMS data set was originally generated to characterize biophysical
change as defined in the International Satellite Land
... Surface Climatology
Project (ISLSCP) Initiative II collection. NDVI , in general is a ratioed
measure of vegetation and is used in climate models and biogeochemical models
to calculate photosynthesis, the exchange of CO2 between the atmosphere and the
land surface, land-surface evapotranspiration and the absorption and release of
energy by the land surface . This data set provides improved results based on
corrections for calibration, view geometry, volcanic aerosols, and other
effects not related to actual vegetation change.
