Effect by Seasons on Backscattering Intensity of ALOS-2 PALSAR-2 Data (L-band) to Retrieval Forest Biomass in Tropical Region

In this research we used the L-band radar from ALOS-2 PALSAR-2 and field work data for evaluation of effects by the season to retrieval forest biomass in tropical region. The effect of seasonality and HH, HV polarizations of the SAR data on the biomass was analyzed. The dry season HV polarization could explain 61% of the biomass in this study region. The dry season HV backscattering intensity was highly sensitive to the biomass compared to the rainy season backscattering intensity.
