MONARCH

The Multiscale Online Nonhydrostatic AtmospheRe CHemistry model (MONARCH) is a chemical weather prediction system, formerly known as NMMB/BSC-CTM, that can be run either globally or regionally. MONARCH, developed at the Barcelona Supercomputing Center, is based on the online coupling of the meteorological Nonhydrostatic Multiscale Model on the B-grid (NMMB) with a full aerosol-chemistry module. Under continuous development. Used as operational model in the WMO Barcelona Dust Forecast Center and the Copernicus Regional Production service.
