NOAA-20 OMPS Sensor Data Record from Early Orbit Operation

The NOAA-20 Ozone Mapping Profiler Suite (OMPS) is the second Ultraviolet (UV) sensor suite in the US Joint Polar Satellite System (JPSS) program. The sensor suite was launched aboard the NOAA-20 spacecraft on Nov. 18, 2017. Like the first OMPS instrument which is flying on the Suomi National Polar-orbiting Partnership spacecraft (S-NPP), the NOAA-20 OMPS contains two advanced nadir viewing hyper-spectral instruments, the Nadir Profiler (NP) and the Nadir Mapper (NM), tracks the health of the ozone layer and measure the concentration of ozone in the Earth's atmosphere. A successful thorough early orbital calibration enabled the current provisional Sensor Data Records (SDRs) stage. We present our analyses and results of the NOAA-20 OMPS early-orbit SDR performance, demonstrate that the sensor smoothly transitioned from ground to orbit by meeting or exceeding sensor level requirements. Our results suggest that a routine calibration of dark current as well as wavelength shifts is critical in the SDR data processing.
