The scatter plots between monthly Thailand gauge and GPCC, 3B42 and 3B43 are displayed in Figure 4. Although there is a negative bias (gauge less than 3B42 and 3B43), there is a tendency of the monthly 3B42 to taper around 5-600 mm/month, and hence there is in fact a positive bias (3B42 > gauge) at rain rates higher than around 400 mm/month. The same is true for 3B43, but to a lesser extent.
