Maturity of Sensor Data Records from NOAA-20 (JPSS-1)

NOAA-20 was successfully launched on November 18, 2017, and this year will mark its first year in operations. All the sensors are performing nominally and this presentation highlights the post launch assessment of the Sensor Data Records from NOAA-20 as the data are transitioned in to operations. ATMS and VIIRS Sensor Data Records (SDRs) have been fully validated; OMPS and CrIS data have reached Provisional level of maturity and are expected to be fully validated by end of August 2018 for CrIS and for OMPS by end of 2018. At the first day (day-1) of NOAA-20 ATMS looking at Earth, NOAA Microwave Integrated Retrieval System was able to generate important environmental data records (EDRs) such as rain rate, cloud water, atmospheric profiles of temperature and water vapor. The data are validated through detailed calibration and validation plans for each sensor. On-orbit Signal to Noise Ratio (SNR) for VIIRS and OMPS, and NEdT for VIIRS, ATMS and CrIS are well within specifications. Striping noise and channel-to-channel noise correlation of ATMS on NOAA 20 are much improved compared to data from SNPP. ATMS data from NOAA-20 has been assimilated in to Numerical Weather Prediction models at the NOAA National Centers for Environmental Prediction and ECMWF and the results are comparable to data from ATMS on SNPP. CCD performance, in terms of electronic bias, readout noise, LED signal drifting, nonlinearity and change in dark currents are all normal for OMPS. NOAA NUCAPS team has generated and analyzed NOAA-20 trace gases, temperature, water vapor and other EDR products and is satisfied with the EDR accuracy.
