Effect of environmental temperatures on SAR forest biomassestimates

摘要

This paper discusses the observed effects of temperatureconditions on estimates of forest biomass in a portion of the Canadianboreal forest. Biomass estimation equations were developed fromrelationships between SAR backscatter and measured forest biomass forseveral forest stands. Separate relationships were developed for SARimages acquired under widely different temperature conditions. Thebiomass estimates obtained from the different images were compared.Differences in observed backscatter behavior and biomass results arediscussed
