MONARCH: Multiscale Online Nonhydrostatic AtmospheRe CHemistry model Version 2.0

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. The NMMB model was developed by the National Oceanic and Atmospheric Administration - Environmental Modeling Center (NOAA/EMC) and distributed on an AS IS basis, without warranties or conditions of any kind, to the Barcelona Supercomputing Center through a Memorandum of Understanding.

The main characteristics of MONARCH are as follows:

• Nonhydrostatic meteorological core allowing both global and regional simulations with embedded telescoping nests.
• Gas-aerosol chemistry packages to solve the tropospheric chemistry of the atmosphere.
• Different meteorology-driven emissions computed on-line: mineral dust, sea salt and biogenic gas species.
• Multiple mineral dust and sea salt source functions available.
• Aerosol-radiation-interaction available.
• Interface with the emission model HERMESv3 to allow rapid deployment of new emission inventories.
• Data assimilation capability coupling MONARCH with a local ensemble transform Kalman filter (LETKF) scheme.
