| Abstract | Monitoring of terrestrial vegetation from satellit es at global and regional scales requires accurate and frequent measurements of surface reflectance. In this context, the POLDER instrument leads a key improvement providing, at high temporal resolution, measurements of the Bi-directional Reflectance Distribution Function corrected for atmospheric effects. In the frame of the ADEOS2/POLDER-2 project, advanced Land Surface Level 3 algorithms have been developed to retrieve the spectral DirectionalHemispherical Reflectances (DHR), the Normalized Difference Vegetation Index (NDVI) corrected for directional effects, the Leaf Area Index (LAI) and the Fraction of Vegetation Cover (FVC). The retrieved parameters are validated following a procedure based upon the analyze of the spatial and temporal variabilit y, the comparison with available equivalent products derived from other sensors by similar or different approaches, and finally the comparison with up-scaled in-situ measurements collected over selected areas. |
