RFMIP

Home

The Radiative Forcing Model Intercomparison Project (RFMIP) will assess sources of error and spread in the radiative forcing calculated by state-of-the-art climate models for historical and future climate studies. RFMIP consists of three linked components: one assessing the forcing by greenhouse gases, one the forcing by aerosols, and one linking these with estimates of effective forcing inferred from global model integrations via careful diagnosis.

Temperature and adjusted radiative forcing time series, from Forster et al. (2013).

Globally-averaged surface temperature change since pre-industrial (a, b) and estimated net radiative forcing (c, d) over the historical period (a, c) and RCP projections from CMIP5 (b, d). Thin lines represent individual model results and thick lines are the multi-model means. RFMIP seeks to understand the degree to which diversity in effective radiative forcing, rather than diversity in climate sensitivity, drives the distribution of temperature changes over time.
