CMIP recommendations for solar forcing over time
Recommendations for the solar forcing in climate models participating in CMIP (or other model comparison projects) have varied over time, and have adopted different assumptions with respect to historical data (from 1850, or for the last millenium) and in future scenarios. This page is a link to those data to aid in comparing results from different CMIP phases.
CMIP7 (2026+)
Historical data: 1850-2023
Scenarios: 2024-2100+
Data source here. Includes TSI, SSI, alternative SSI (SATIRE), and particle forcing data.
CMIP6 (2016-2025)
Historical data: 1850-2014
Scenarios: 2015+
Data source here. Includes a 'consensus' TSI, SSI and particle forcing.
.CMIP5 (2010-2015)
Historical data: 1850-2008
Scenarios: 2009-2100
Data source here. Includes TSI with and without a varying background (Wang et al., 2005).
CMIP3 (2004-2009)
Historical data: 1850-2000
Scenarios: 2001-2100 (repeated cycle 23)
Data source here. Includes TSI and SSI from Lean (2002)
