14 15 This article describes the algorithmic principles used to generate LAI, fAPAR and fCover 16 estimates from VEGETATION observations. These biophysical variables are produced 17 globally at 10 days temporal sampling interval under lat-lon projection at 1/112° spatial 18 resolution. After a brief description of the VEGETATION sensors, radiometric(More)
The Globcover initiative comprises the development and demonstration of a service that in first instance produces a global land cover map for year 2005/2006. Globcover uses MERIS fine resolution (300 m) mode data acquired between mid 2005 and mid 2006 and, for maximum user benefit, the thematic legend is compatible with the UN land cover classification(More)
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 inversion(More)
Airborne Polarization and Directional Earth Radiation (POLDER) data acquired during the boreal ecosystematmosphere study (BOREAS) and the four-scale model of Chen and Leblanc [10] are used to investigate radiative transfer in boreal forest. The four-scale model is based on forest canopy architecture at different scales. New aspects are incorporated into the(More)
Inundation is linked to water, carbon, and energy budgets at landscape to global scales. We describe a new remote-sensing technique for identifying inundated areas based on the properties of the glitter—the strong, angular signature reflection that is characteristic of surface water and uncharacteristic of other cover types. We discriminated three cover(More)
