WACCM: Whole Atmosphere Community Climate Model

The Whole Atmosphere Community Climate Model (WACCM) is a comprehensive numerical model, spanning the range of altitude from the Earth's surface to the thermosphere. The development of WACCM is an inter-divisional collaboration that unifies certain aspects of the upper atmospheric modeling of HAO, the middle atmosphere modeling of ACD, and the tropospheric modeling of CGD, using the NCAR Community Earth System Model (CESM) as a common numerical framework.

WRF: Weather Research and Forecasting

The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs.

NRCM: Nested Regional Climate Model

The Nested Regional Climate Model (NRCM) combines the strengths of NCAR's Weather Research and Forecasting (WRF) model and NCAR's Community Earth System Model (CESM) into an instrument that will allow for fundamental progress on the understanding and prediction of regional climate variability and change.

NCAR Master Mechanism: NCAR Master Mechanism

The NCAR Master Mechanism is an explicit and detailed gas phase chemical mechanism combined with a box model solver. User inputs include species of interest, emissions, temperature, dilution, and boundary layer height. Any input parameter may be constrained with respect to time. Photolysis rates are calculated using the TUV model, included in the code package. The model is written in a mixture of F77 and Fortran90, and is managed using C-shell scripts. 

MEGAN: Model of Emissions of Gases and Aerosols from Nature

MEGAN is a modeling system for estimating the net emission of gases and aerosols from terrestrial ecosystems into the atmosphere.

MPAS: Model for Prediction Across Scales

The Model for Prediction Across Scales (MPAS) is a collaborative project for developing atmosphere, ocean and other earth-system simulation components for use in climate, regional climate and weather studies. The primary development partners are the climate modeling group at Los Alamos National Laboratory (COSIM) and NCAR's Earth System Laboratory.

MOZART: Model for OZone and Related chemical Tracers

The Model for OZone and Related chemical Tracers (MOZART) is a global 3-D chemical transport model, driven by offline meteorological fields, that has been developed at NCAR, the Max-Planck-Institute for Meteorology, and NOAA/GFDL. MOZART-3 includes tropospheric and stratospheric chemistry and MOZART-4 is particularly suited for tropospheric and air quality studies.

CESM: Community Earth System Model

The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.
