DAMIP is part of the Coupled Model Intercomparison Project Phase 6 (CMIP6), a coordinated international effort "to better understand past, present and future climate changes arising from either natural, unforced variability or in response to changes in radiative forcing in a multi-model context."
DAMIP is the component of CMIP6 dealing with understanding the individual contributions of various external factors to past and future changes in global and regional climate.
primary goals of DAMIP are to facilitate improved estimation of the
contributions of anthropogenic and natural forcing changes to
observed global warming as well as to observed global and regional
changes in other climate variables; to contribute to the estimation
of how historical emissions have altered and are altering
contemporary climate risk; and to facilitate improved
observationally-constrained projections of future climate change.
