NOAA, through the Joint Polar Satellite System (JPSS) program, in partnership with National Aeronautical Space Administration (NASA), will launch the NPOESS Preparatory Project (NPP) satellite in October 2011. The JPSS program will execute the NPP Calibration and Validation (Cal/Val) program to ensure the data products comply with the requirements of the sponsoring agencies. The Ozone Mapping and Profiler Suite (OMPS) consists of two telescopes feeding three detectors measuring solar radiance scattered by the Earth's atmosphere and solar irradiance by using diffusers. The measurements are used to generate estimates of total column ozone and vertical ozone profiles. The validation efforts will make use of external resources in the form of ground-based and satellite measurements for comparisons and internal consistency methods developed over the last thirty years. This poster will provide information on the state of the execution of the OMPS Cal/Val Plan with emphasis on the measures of the instrument performance from internal consistency analysis techniques and comparisons to other satellite instrument products for the validation of the NPP OMPS environmental data products.
