From the statistical analysis, the GPCC and the
TRMM 3B43 are close to gauges estimates. 3B42 is
in general higher than the gauge estimates, except for
DJF in the North and South regions and JJA in the
East region. This is consistent with the results of Chiu
and Shin (2004) who found a similar difference
between 3B42 and 3B43.
Future work will include examination of the daily
differences at the grid and regional scale for different
seasons, and other statistics, such as detection
probability, false and non-detection rates.
This daily data set will be useful for comparison or
validation of the high temporal (daily or 3-hourly) and
spatial (1 degree to 0.25 degree) resolution rain
