Community models

The models described below are available for use on NCAR computers that CISL manages.

Please contact us if you need assistance.

  • Community Earth System Model (CESM)  A fully coupled, global climate model developed at NCAR. CESM (formerly CCSM) provides state-of-the-art computer simulations of the Earth's past, present, and future climate states. 
  • Weather Research & Forecasting (WRF) model  A next-generation mesoscale, numerical weather-prediction system designed to serve both operational forecasting and atmospheric research needs.
  • Whole Atmosphere Community Climate Model (WACCM)  A comprehensive numerical model spanning the range of altitude from the Earth's surface to the thermosphere, developed by a collaboration of NCAR’s High Altitude Observatory, Atmospheric Chemistry Observations & Modeling, and Climate and Global Dynamics division.
  • Atmospheric chemistry models  NCAR’s Atmospheric Chemistry Observations & Modeling supports models for regional and global air quality and chemistry and climate change, including MOZART, CAM-chem, and WACCM.
  • Thermospheric General Circulation Models (TGCMs)  The High Altitude Observatory (HAO) at NCAR has developed a series of numeric simulation modelssuch as TIEGCM and TIME-GCMof the Earth's upper atmosphere, including the upper stratosphere, mesosphere, and thermosphere.
  • Data Assimilation Research Testbed (DART)  A community facility for ensemble data assimilation developed and maintained by NCAR’s Data Assimilation Research Section (DAReS).
