Input data set: Historical observed climate data



Protocol relation: Protocol
Data Type: Observed atmospheric climate
Simulation rounds: ISIMIP2a
Description:

Daily-resolution observed climate data on a global (land and ocean) 0.5°x0.5° lat-lon grid.

GSWP3
Derived from the Global Soil Wetness Project Phase 3 (GSWP3), based on the reanalysis data set 20CR and using the bias targets GPCC, GPCP, CPC-Unified, CRU and SRB. This data set covers the period 1901‐2010.

GSWP3-EWEMBI
EWEMBI global meteorological forcing data processed for ISIMIP2a (http://doi.org/10.5880/pik.2019.004). Contains EWEMBI data and data from the GSWP3 dataset, developed by Hyungjun Kim with support by the Japan Society for the Promotion of Science KAKENHI (16H06291). This data set covers the period 1979-2016.

GSWP3-W5E5
W5E5 global meteorological forcing data processed for ISIMIP2a/ISIMIP3a (http://doi.org/10.5880/pik.2019.023). Contains W5E5 data and data from the GSWP3 dataset, developed by Hyungjun Kim with support by the Japan Society for the Promotion of Science KAKENHI (16H06291). This data set covers the period 1979-2016.

PGMFD v2.1 (Princeton)
Derived 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. This data set covers the period 1901‐2012.

WATCH (WFD)
Derived from the WATCH Project, based on the reanalysis data set ERA-40 and using the bias target GPCC. The data set covers the period 1901‐2001.

WATCH-WFDEI
Based on the reanalysis data set ERA-Interim and using the bias target GPCC. The data set covers the period 1901‐2012, where the data for 1901-1978 are taken from WFD, and from 1979 onwards from WFDEI.GPCC
