The horizontal resolution of these products varies by
an order of magnitude, which means that the products differ
in their ability to resolve rainfall features. The CMAP and
GPCP products are available at a resolution of 250 km and
extend over 29 years. The TRMM data are of much higher
spatial resolution (25 km) but they are only available for a
shorter period (1999 to 2011).
et al., 2010], and Peru [Condom et al., 2011]. For example,
Zhou and Wang [2006] used TRMM data to study the diurnal
cycle of rainfall over the New Guinea region and identified the
relatively complex interaction between convective activity,
land-sea breezes, and orography. Chang et al. [2005] used
TRMM data to demonstrate a strong relationship between
rainfall and winds over much of south-east Asia, including
West Irian.
