OPERATIONAL DERIVATION OF SURFACE ALBEDO AND DOWN-WELLING SHORT-WAVE RADIATION IN THE SATELLITE APPLICATION FACILITY FOR LAND SURFACE ANALYSIS

摘要

The Satellite Application Facility for Land Surface Analysis hosted by the Portuguese Meteorological Institute in Lisbon generates and distributes value added satellite products for numerical weather prediction and environmental applications in near-real time. Within the project consortium Meteo-France is responsible for the land surface albedo and down-welling short-wave radiation flux products. Since the beginning of the year 2005 Meteosat Second Generation data are routinely processed by the Land-SAF operational system. In general the validation studies carried out so far show a good consistency with in-situ observations or equivalent products derived from other satellites. After one year of operations a summary of the product characteristics and performances is given.
