Mario Raffa got a Master Degree in Electronic Engineering for Automation and Telecommunications at University of Sannio in 2014. Since 2022 he has been research unit leader of REM (REgional Models) for REMHI division of CMCC Foundation, after working as a research assistant from 2015 to 2021. His main activity concerns convective-scale climate simulations, with experience on the regional climate models COSMO-CLM and ICON-CLM. He has experience in the development of statistical-numerical algorithms for weather forecasting and the processing of satellite and climate data, as well as in the development of operational chains and management of long-term simulations in an HPC environment. He is part of the coordination group of the CLM-Community and deputy coordinator of the SOILVEG working group (soil and vegetation). He is mainly involved in the CORDEX – Flagship Pilot Studies initiative, both CPM (Convection Permitting Models) and LUCAS (Land Use & Climate Across Scales), EUROCORDEX and he took part in different research projects, WEC (Climate Kic), EUCP (H2020), NEXTDATA (FISR), Copernicus Climate Change Service C3S (ECMWF), HIGHLANDER (EC).
