The overall objective of this research is to support the ARM BBHRP measurement-model comparison effort that will couple heating rates based on ARM data more directly into SCM and GCM models. We are making use of high spectral resolution infrared satellite, aircraft, and ground based data for assessing the model parameterizations that are candidates for relating ARM time sequences to statistical cloud and radiation properties on the GCM grid cell scale. This is expected to contribute toward the ARM Program objective of gathering data and techniques needed to provide refined parameterizations for climate models. Our effort includes both clear and cloudy sky BBHRP assessments at the SGP, NSA, and TWP sites using observed radiances and derived products (atmospheric soundings, cloud fraction and property retrievals, surface retrievals) from the high spectral resolution sensors AERI, Scanning-HIS, and AIRS. This poster presents our initial analyses of clear sky cases from the SGP site. AERI and AIRS observations are used to assess the accuracy and representativeness of clear sky LBLRTM radiance calculations for the surface and Top-of-Atmosphere (TOA). Surface and TOA fluxes are then assessed by comparing LBLRTM/RRTM flux calculations to the surface and TOA flux observations used in BBHRP.
This poster will be displayed at the ARM Science Team Meeting.
