Abstract

Prognostic aerosols were experimentally introduced in the ECMWF Integrated Forecasting System as part of the GEMS project in 2005. Their representation was refined as part of the MACC project, starting in 2009. Differences between the two systems are first discussed and results of comparisons of aerosol optical depth with satellite and AERONET ground station observations are discussed.
