System for Integrated Modeling of the Atmosphere

SIMA brings together Weather, Climate, Chemistry and Geospace Community Models at NCAR

SIMA is a unified community atmospheric modeling framework, for use in an Earth System Model (ESM). SIMA enables diverse configurations of an atmosphere model inside of an ESM for applications spanning minutes to centuries and cloud to global scales, including atmospheric forecasts and projections of the atmospheric state and composition from the surface into the thermosphere.
