Cloud & Aerosol Processes: Models

A variety of models are used to conduct Cloud & Aerosol Processes research. These include RAMS/LES and WRF-Chem.

Large Eddy model

The Regional Atmospheric Modeling System in large eddy simulation mode (RAMS/LES) is a scalable model operated in LES mode with coupled dynamics, size resolved microphysics, and aqueous sulfate chemistry.

Parcel model

The adiabatic cloud parcel model includes size-resolved microphysics and gas and aqueous phase chemistry. Aerosol/cloud droplets are resolved in size categories on a moving grid scale.


The Weather Research and Forecasting (WRF) model is a numerical weather prediction and atmospheric simulation system designed for both research and operational applications. The WFR-Chem model provides a capability for air chemistry modeling.
