Input data set: UKESM1-0-LL

Climate related forcing: Simulated atmospheric climate.

Pre-industrial (1601-1849), historical (1850-2014) and future (2015-2100) conditions provided based on the bias adjustment and statistical downscaling of CMIP6 output from UKESM1-0-LL, using ISIMIP3BASD v2.5.0 and W5E5 v2.0.

CMIP6 experiments used in ISIMIP3b are piControl, historical, ssp126 (SSP1-RCP2.6), ssp370 (SSP3-RCP7) and ssp585 (SSP5-RCP8.5).

The method used for bias adjustment and statistical downscaling in ISIMIP3b is version 2.4.1 of ISIMIP3BASD (Lange, 2019a, 2020). The observational reference dataset used for bias adjustment and statistical downscaling in ISIMIP3b is version 1.0 of WFDE5 over land merged with ERA5 over the ocean (W5E5; Lange, 2019b; Cucchiet al., 2020).

Original GCM data have been extracted from the CMIP6 archive.
