W5E5 global meteorological forcing data processed for ISIMIP2a/ISIMIP3a. 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).

Original W5E5 data covers the entire globe at 0.5° horizontal and daily temporal resolution from 1979 to 2016 (

In order to minimize discontinuities at the 1978/1979 transition, GSWP3 data were homogenized with W5E5 data using the ISIMIP2BASD v2.3 bias adjustment method (

**ISIMIP3a update**: Combination of W5E5 for 1979-2016 with GSWP3 homogenized to W5E5 for 1901-1978. The homogenization reduces discontinuities at the 1978/1979 transition and was done using the ISIMIP3BASD v2.4.1 bias adjustment method. For further information, see:
