– The Bidirectional Reflectance Distribution Function (BRDF) of several plant canopies was extensively sampled by the POLDER airborne instrument in the Alpilles-ReSeDA campaign. The 16 flights carried out over the Alpilles test site from January to October 1997 cover all the plant growth stages. Estimation of biophysical variables was undertaken by(More)
INTRODUCTION The knowledge of canopy biophysical variables is of prime interest in many applications including crop functioning modeling, evapotranspiration and crop yield prediction. Moreover, establishing maps of biophysical characteristics is necessary for predicting the soil-vegetation-atmosphere transfers. Large swath sensors with relatively high(More)
