摘要：
In this study, changes in the temporal and volume contributions (|gamma|(temporal), |gamma|(volume)) to the observed ERS-1/2 coherence are modelled in response to an increase of forest woody biomass in Central Siberia. It is demonstrated that the distance between neighbouring trees and the vertical structure of boreal forest canopies must be accounted for to model |gamma|(volume). Results confirm that |gamma|(temporal) is the main decorrelation factor although |gamma|(volume) contributes significantly to the overall loss of coherence observed over mature forests.
