Abstract

This paper discusses the observed effects of temperature conditions on estimates of forest biomass in a portion of the Canadian boreal forest. Biomass estimation equations were developed from relationships between SAR backscatter and measured forest biomass for several forest stands. Separate relationships were developed for SAR images acquired under widely different temperature conditions. The biomass estimates obtained from the different images were compared. Differences in observed backscatter behavior and biomass results are discussed
