This technical report summarizes the SINTEX-G (INGV-SXG) model technical structure. INGV-SXG is an Atmosphere Ocean sea-ice General Circulation Model (AOGCM) developed at INGV with the aim of investigating the features and the mechanisms of the climate variability and change.
This model was used to produce the INGV-CMCC Intergovernmental Panel on Climate Change (IPCC) scenario simulations. INGV-SXG is an evolution of SINTEX and SINTEX-F and this report indicates the improvement with respect to these previous INGV AOCM model: the new model includes a thermodynamic-dynamic sea-ice model and the capabilities to use external radiative forcings (Ozone, Sulfate Aerosols, Greenhouse Gases) as specified in the protocol for the IPCC standard experiments.
The description of model components, coupling methods, compiling and running environments is a guideline for model users.
