Input data set: PGMFD v.2 (Princeton)

Daily-resolution observed climate data on a global (land and ocean) 0.5°x0.5° lat-lon grid from the Terrestrial Hydrology Group at Princeton University, based on the reanalysis data set NCEP/NCAR Reanalysis I and using the bias targets CRU, SRB, TRMM, GPCP & WMO and validated against GSWP2. The data set covers the period 1901‐2012
