The GOES-8 Imager and Sounder Radiometric Performance Models are flexible tools intended to provide a intuitive user interface to instrument sensitivity analysis. The models were developed at Lockheed Martin IR Imaging Systems and transferred to the GOES modeling community as the standard for projecting the instruments' IR sensitivity in units of noise-equivalent delta radiance, under arbitrary user- imposed conditions. In addition, the models provide an efficient means for selecting flight IR detectors with the highest possible instrument performance. THe radiometric models have shown the way to several instrument-level performance improvements, and have also been a valuable tool in troubleshooting anomalous measurements at various stages of the GOES instrument build. The operation of the GOES-8 SOunder Radiometric Performance Model is described herein in terms of input parameters, calculational flow, and output results.
