Relationships between the 10-day accumulated precipitation before the PALSAR
observation date and PALSAR γ0
HV. Each point shows the average value of 300-point
reference data in each test site. The solid and dashed lines are regression lines for
the deforested area (y = 0.0077x − 14.62, R = 0.432, p b 0.05) and the natural forest
(y= 0.0015x − 11.81, R = 0.367, p b 0.05), respectively.
