Abstract

The overall objective of the ERS-1 proposal in conjunction with the SIR-C mission and in preparation for Eos is to perform coordinated global forest experiments designed to use the unique properties of SAR to characterise the physical nature of forest stands as input to ecosystem and climatology models. The specific objectives of the ERS-1 mission are: 1) to quantify the temporal range of radar returns from a variety of forest canopy types under different growth stages and environmental and seasonal conditions. 2) to unfold the components of backscatter from a forest stand using the observations made under a variety of environmental conditions, 3) to quantify radar signatures in terms of physical forest ecosystem characteristics including above-ground phytomass, canopy geometry (size, shape, angular orientation), canopy moisture condition, and surface boundary-layer (SBL) state, and 4) to map and monitor human impacts on forest canopies including: a) acid-deposition damage in Europe, in the eastern US, and Canada, as well as other stress conditions, b) biomass burning in Australia and Alaska, and c) deforestation in the northern U.S., Canada and Brazil, if a receiving station is available.
