Representação espacial do albedo superficial a partir dos sensores remotos AVHRR e ERBE durante as estações chuvosa e menos chuvosa para Floresta Tropical Amazônica.

Abstract

Surface albedo is an important parameter that affects the terrestrial radiation balance and has been considered in studies of global climate. The goal of this work is to determine spatially the albedo of an Amazon tropical rainforest from the average monthly data of AVHRR and ERBE remote sensors for the wet and less wet seasons. The results show that the albedos obtained by the two sensors are distinct, probably due to the spectral bands used by the ERBE in the determination of albedo represent lager part of the solar radiation spectrum.
