Abstract. A representation of atmospheric chemistry has been included in the Integrated Forecasting System (IFS) European Centre for Medium-Range Weather Forecasts (ECMWF). The new modules complement aerosol IFS composition, which is named C-IFS. C-IFS supersedes a coupled system chemical transport model (CTM) Model OZone and Related Tracers 3 was two-way to (IFS-MOZART).

Abstract. In this work, we assess the ability of RegCM4 regional climate model to simulate surface solar radiation (SSR) patterns over Europe. A decadal run (2000–2009) was implemented and evaluated against satellite-based observations from Satellite Application Facility on Climate Monitoring (CM SAF), showing that simulates adequately SSR region. The bias between CM SAF is +1.5 % for MFG (Meteosat First Generation) +3.3 MSG Second observations. relative contribution parameters determine...

Abstract. The MACC reanalysis dust product is evaluated over Europe, northern Africa and the Middle East using EARLINET-optimized CALIOP/CALIPSO pure satellite-based LIVAS (2007–2012). optical depth at 550 nm (DOD550) data are compared against DOD532 observations. As only natural aerosol (dust sea salt) profiles available in MACC, here we focus on layers above 1 km a.s.l. to diminish influence of salt particles that typically reside low heights. So, extinction coefficient 532 from LIVAS,...
