Suomi NPP OMPS Radiometric Calibration Sensitivity Evaluation on OMPS SDR and EDR

Ozone Mapper Profiler Suite (OMPS) on Suomi National Polar-orbiting Partnership (S-NPP) and the future Joint Polar Satellite System 1 (JPSS-1) OMPS sensors including a Nadir Mapper (NM) to provide total column (TC) ozone through Huggins absorption and UV reflection, a Nadir Profiler (NP) to measure the vertical distribution of ozone in Hartley band. It is important to understand the influence of OMPS NM and NP radiometric calibration on the Sensor Data Record (SDR) and Environment Data Record (EDR). This study will present S-NPP radiometric calibration characteristic updates including calibration coefficient, irradiance calibration coefficient, channel band center and solar flux, as well as the sensitivity evaluations on OMPS SDR and EDR products. National Oceanic and Atmospheric Administration (NOAA)'s Interface Data Processing Segment (IDPS) Algorithm Development Library (ADL4.2 MX8.8) is used to generate OMPS SDR and EDR with PEATE S-NPP calibration updates, where the SDR is assessed by comparing via Simultaneous Nadir Overpass (SNO) with Global Ozone Monitoring Experiment-2 (GOME-2) L1B product on METOP-A/B.
