The characteristics of PALSAR γ0
HH and γ0
HV for natural forests and
deforested areas are shown in Fig. 5. Table 3 shows the average and
standard deviation of γ0 in natural forests and deforested areas. There
were no clear differences between dry forests (sites D1–D3) and wet
forests (sites W1–W3). The average γ0
HH did not show clear changes
between deforested areas and natural forests, but the average γ0
HV of
deforested areas was systematically lower by 1–4 dB than that of natural
forests
