Please contact the NCAR Research Computing help desk 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. The CESM simulation image above is from the CISL Visualization Gallery.

  • 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 builds, critically evaluates, and applies process, regional- and global-scale models that address atmospheric chemistry research questions, with a focus on couplings between different components of the Earth system.                               

  • Thermospheric General Circulation Models (TGCMs) – The High Altitude Observatory (HAO) at NCAR has developed a series of numeric simulation models – such as TIEGCM and TIME-GCM – of 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).
