Fourteenth Atmospheric Radiation Measurement (ARM) Science Team Meeting
Radiative transfer models developed at Atmospheric and Environmental Research, Inc. (AER) are being used extensively for a wide range of applications in the atmospheric sciences. The RT models span a spectral range from the microwave to the ultraviolet, and range from monochromatic to band calculations. The accuracy that the AER models currently demonstrate has been attained as a consequence of two important initiatives: (1) the continuing improvement in the quality of the line parameters contained in the HITRAN database (http://www.hitran.com) and (2) the spectral radiometric measurements obtained by the University of Wisconsin group using interferometers with high photometric accuracy. The role of medium-resolution spectral radiance measurements of high radiometric accuracy obtained from the surface (e.g. Atmospheric Emitted Radiance Interferometer (AERI)), and from medium and high altitude interferometers (e.g. High resolution Interferometric Sounder (HIS)) cannot be overemphasized. These measurements in conjunction with the accurate specification of atmospheric state, such as profiles obtained at the Atmospheric Radiation Measurement program (ARM) Southern Great Plains (SGP) site, have had an important influence in the development of model parameterizations including the water vapor continuum and the line shape and continuum associated with carbon dioxide. In this poster presentation we will include summaries and recent updates to the following models: Line-By-Line Radiative Transfer Model (LBLRTM); the associated line file creation code (LNFL); the longwave and shortwave rapid radiative transfer models, RRTM and RRTM_SW; Monochromatic Radiative Transfer Model (MonoRTM); and the MT_CKD Continuum. These models are available at the AER web-site: http://www.rtweb.aer.com.
