- This data is an end product (will not be updated). Combines MERRA reanalysis with observation-based datasets. Wet days: MERRA-Land and CRU wet days for each month in each year. Mean: MERRA-Land daily values multiplied by correction factor imposing mean of CRU, GPCC, and UDEM for each month and each year at 0.5 resolution. 0.25° details imposed from average monthly spatial pattern drawn from ensemble of TRMM, CMORPH, and PERSIANN.
