7. DATASET OVERVIEW

7.1 Abstract

The CMIP5_CDFDM_S14FD dataset is bias-corrected CMIP5 GCM daily data developed using CDFDM as the bias-correction method and S14FD as the reference. The dataset offers daily data of 11 climatic variables over the globe from 1961 to 2100 under 4 RCPs and 8 GCMs. The data over the sea and Antarctica are not bias-corrected (i.e., the raw GCM data were used), whereas those over the land are bias-corrected. Variables include daily mean 2m air temperature (tave2m, °C), daily maximum 2m air temperature (tmax2m, °C), daily minimum 2m air temperature (tmin2m, °C), daily total precipitation (precsfc, mm d-1), daily mean downward shortwave radiation flux (dswrfsfc, W m-2), daily mean downward longwave radiation flux (dlwrfsfc, W m-2), daily mean 2m relative humidity (rh2m, %), daily mean 2m specific humidity (spfh2m, kg kg-1), daily mean 2m vapor pressure (vap2m, hPa), daily mean 10m wind speed (wind10m, m s-1) and daily mean surface pressure (pressfc, hPa).
