Abstract

Fraction of Absorbed Photosynthetically Active Radiation (FPAR), determined from remote sensing data, can vary with the spatial resolution, the different retrieval algorithms and viewing angels of the used data. This paper aimed at evaluating MODIS, POLDER and CYCLOPE global FPAR products, and found that the MODIS FPAR was larger than CYCLOPES, and their difference ranged within 0.1~0.2, especially at the forest area where MODIS product always presented seasonal variation in this area while CYCLOPES products kept relatively stable. For other vegetation covers, their difference was less than 0.1. Furthermore, the comparison of MODIS and POLDER FPAR products shown that the MODIS FPAR was also larger than the POLDER and their difference was up to 0.1 to 0.2.
