Paul van Delst will be visiting CIRA from the Joint Center for Satellite Data Assimilation (JCSDA). His talk will focus on development of the CRTM. The CRTM is a widely used radiative transfer model that is suited to create synthetic satellite imagery from numerical model output. In addition to generating synthetic GOES imagery, the CRTM can be used to create top of the atmosphere radiances for a wide range of geostationary and polar orbiting platforms.
