The results revealed that the combined data after the
Bayesian correction improved significantly compared to the
uncorrected data (original GPCP and real-time satellite data
stitched together—see table 1). Figures 3 and 4 confirm
that the combined GPCP-PERSIANN and GPCP-TRMM-RT
exhibited less error during the validation period (2010) after
implementing the correction. Furthermore, several major
drought such as the 2011 Texas, 2010 Horn of Africa,
and 2010 Amazon droughts were detected in the combined
real-time and long-term satellite observations. This highlights
the potential application of satellite precipitation data for near
real-time global drought monitoring.
