Monitoring Of Suomi-Npp Omps Calibration Parameters And Understanding Their Impacts On Earth View Radiance

The key calibration parameters important to instrument health and safety of Ozone Mapping Profiler Suite (OMPS) Nadir Sensors on board Suomi NPP (Suomi National Polar-orbiting Partnership) are being monitored since November 2011 at NOAA/ STAR by the Intensive Calibration and Validation System (ICVA). OMPS has two instrument modules: a combined Nadir Mapper (NM) and Nadir Profiler (NP), and a separate Limb Profiler (LP). Both nadir sensors are designed to make measurements of the ultraviolet radiance backscattered by the Earth's atmosphere and surface and of the extra-terrestrial solar irradiance. In this paper, the trending of the OMPS key calibration parameters in the past four years is shown. The impacts of these parameters on OMPS earth view radiance and albedo for nadir sensors are analyzed.
