CATChem

CATChem (Configurable ATmospheric Chemistry) is a modelling component that includes all chemical and aerosol processes needed to perform atmospheric chemistry and composition simulations within a model through a flexible, easy to modify, and well-documented infrastructure. CATChem will include the following processes: chemical kinetics, aerosols, photolysis, wet deposition, dry deposition, connections to emissions, and connection to physics schemes. The first use of CATChem will be connecting it to NOAA’s Unified Forecasting System (https://ufscommunity.org/) to create UFS-Chem. CATChem and UFS-Chem are currently under development and more information will be provided soon.

Warning

CATChem is currently under development. The code is public to encourage collaboration amongst the community. Do not publish results using CATChem without consulting the development team.
