The objective of the Coupled Model Intercomparison Project (CMIP) is to better understand past, present and future climate changes arising from natural, unforced variability or in response to changes in radiative forcing in a multi-model context. An important goal of CMIP is to make the multi-model output publically available in a standardised format. In fact, climate research centres worldwide (more than 30 research centres are involved in this activity today) provide their simulation output following common protocols not only in terms of radiative forcing path but also in terms of data format. The CMIP output is the base to draw up the regular (about every 7 years) Assessment Report of the Intergovernmental Panel on Climate Change. CMIP began in 1995 and CMCC has participated in this effort since 2008 when the SINTEX-G model was involved in CMIP3 simulations. CMCC-CM model, instead, was used for the provision of the simulations following CMIP5 in 2013.
In the 6th phase of the Coupled Model Intercomparison Project (CMIP6) CMCC contributed by producing numerical simulations with both Global Coupled Climate and Earth System models. This contribution accounts for the reference DECK experiments (1979-2014 AMIP, Pre-industrial control, 1% annual CO2 increase and abrupt 4x CO2 increase) and the historical simulation (1850-2014), along with simulations specifically designed to address scientific questions of different MIPs, like e.g. future scenarios within the ScenarioMIP.
In Table1 are reported all the simulations performed with CMCC models.
The reference CMIP6 climate model CMCC-CM2 (Cherchi et al, 2018) is declined into two different configurations addressing a standard setup with both atmosphere and ocean at 1 degrees of horizontal resolution (CMCC-CM2-SR5) and a high resolution one with atmosphere at 1 degree and ocean at ¼ of degree (CMCC-CM2-HR4). An additional configuration was implemented to reach a very high representation of both atmosphere and ocean at ¼ of degree (CMCC-CM2-VHR4) in order to address the scientific objectives of the HighResMIP initiative.
The reference CMIP6 Earth System Model named CMCC-ESM2 shares the same physical core of the standard configuration climate model and it allows to explicitly simulate the global carbon cycle due to the complex biogeochemical dynamics within the terrestrial and marine systems.
All data produced within the CMIP6 initiative are made available on the ESGF grid federation through the CMCC data node.
