Influence des surfaces terrestres sur l'erreur d'estimation des précipitations quotidiennes par satellite en Amazonie brésilienne

Abstract : Quantitative precipitation estimates by remote sensing are performed on two areas with different physical properties: a forest area and deforested area in the Brazilian Amazonia. Rainfall ground data are used as a reference for validation of the merged satellite product CMORPH and the microwave product MWCOMB. The statistical results show larger errors for both satellite products over forest area. On this land surface, precipitation estimates by microwave are relatively inaccurate.
