Combination of W5E5 v2.0 (Cucchi et al., 2020, DOI: 10.5194/essd-2020-28 and Lange et al., 2021, DOI: 10.48364/ISIMIP.342217) for 1979-2019 with 20CRv3 (ensemble member 1 of NOAA-CIRES-DOE 20th Century Reanalysis version 3) homogenized to W5E5 for 1901-1978. The homogenization was done in the same way as for GSWP3-W5E5: it reduces discontinuities at the 1978/1979 transition and was done using the ISIMIP3BASD v2.5.0 bias adjustment method (Lange, 2019, DOI: 10.5194/gmd-12-3055-2019 and Lange, 2021, DOI: 10.5281/zenodo.4686991).
