Abstract:
The development of the Community Radiative Transfer Model (CRTM) and its subsequent improvements has created a critically important tool enabling accurate data assimilation of a wide variety of satellite observations made under all weather conditions. Originally developed by Paul van Delst in 2004, The CRTM has been continuously improved and extended by STAR and EMC scientists working with the Joint Center for Satellite Data Assimilation (JCSDA). CRTM supports all current operational and many research satellite measurements, covering wavelengths ranging from the visible through the microwave. The CRTM is used in the NOAA/NCEP and U.S. Navy operational data assimilation systems and by many other JCSDA partners such as NOAA/NESDIS/STAR, NOAA/OAR, NASA/GMAO, Naval Research Laboratory, Air Force Weather, and within multiple university environments.
This presentation will describe the scientific and technical basis of CRTM, including its many strengths and limitations. There will also be a brief overview of the current status of CRTM version 2.3.0; and the future planned release of CRTM version 3.0.0, which will represent a major milestone in CRTM development and capabilities.
