The Community Radiative Transfer Model (CRTM) is a broadband fast radiative transfer model developed at the Joint Center for Satellite Data Assimilation (JCSDA), with the contributions from multiple U.S. government agencies, universities, as well as private companies. The CRTM has been widely used for the purposes of satellite radiance simulation, data assimilation, instrument calibration/validation, and satellite products retrieval.

With the Joint Polar Satellite System – 1 (JPSS-1) launch date approaching, we prepared the JPSS-1 ATMS (boxcar), CrIS (same as CrIS_NPP), and VIIRS (real SRF). Another new version ATMS_J1 coefficient was generated based on the latest real SRF released by NASA recently. To support the Operationally Responsive Space – 6 (ORS-6) mission, we generated Compact Ocean Wind Vector Radiometer (COWVR) coefficient, which has fully-polarimetric imaging radiometer system operating at 18.7, 23.8 and 33.9 GHz. In the presentation we will provide more information about the CRTM coefficient updates, including some details of the real SRF ATMS_J1 and COWVR_ORS6 simulations.
