Abstract

The POLDER-2 sensor has been launched onboard the ADEOS-2 platform in December 2002. It provides measurements of the land surface BRDF from April 2003. The retrieval algorithms of the Level 3 bio-geophysical parameters have been improved by adding a temporal filtering module, a temporal weighting on the synthesis period, and the calculation of an error associated with each parameter. Furthermore, the LAI and the Fraction of Vegetation cover are now assessed using a neural network approach. A validation plan has been worked out to estimate the accuracy of bio-geophysical parameters for the user community.
