The use of ERS2 SAR for assessment of changes in dry herbaceous biomass

Changes and spatial pattern of dry herbaceous biomass was monitored using backscatter coefficients in a time series of ERS-2 SAR images of the semi-arid savanna in Senegal, West Africa. The results were compared to in situ measurements of dry biomass. It has been demonstrated, that the overall spatial and temporal change in SAR backscatter correspond to the changes in biomass, however, the quantitative relation remains to be established.
