Abstract

PALSAR data acquired with 34.3° and 23.1° are used to derive regression models between σ 0 and above ground biomass. Field data were taken in Tomakomai national forest located in northern Japan. Dynamic range of 4dB are observed for 34.3°, and this is larger than that of 3dB for 23.1°. The correlation coefficient for 23.1° is higher than that for 34.3° in both HH and HV polarization, which may be explained by the larger contribution of double bounce scattering from well aligned planted forest. Regression models derived from other L-band SAR data are also plotted to compare our data. Except for one data, the models are moderately matched with each other.
