First results from Version 7 TRMM 3B43 precipitation product in combination with a new downscaling-calibration procedure

► Version 7 TRMM 3B43 precipitation product was used. ► We created 1 km monthly precipitation for a humid area and a semi-arid area. ► NDVI-based downscaling method was extended to a humid area. ► Calibration and disaggregation was conducted to the downscaled annual precipitation. ► Monthly fractions from TRMM 3B43 data can disaggregate annual precipitation.
