SNPP and NOAA-20 VIIRS on-orbit geolocation trending and improvements
Earth Observing Systems XXV, 2020Two Visible Infrared Imaging Radiometer Suite (VIIRS) sensors have been in operations for more than 8.5 and 2.5 years since they were launched in October 2011 on SNPP satellite and in November 2017 on NOAA-20 satellite, respectively. These are two satellites in the Join Polar Satellite System (JPSS) constellation, of which Suomi National Polar-orbiting

A large decline of tropospheric NO2 in China observed from space by SNPP OMPS
Science of the Total Environment, 2019Nitrogen oxides (NOx) are important constituents of air pollution. Here we use retrievals of tropospheric NO2 column from the Ozone Mapping Profiler Suite (OMPS) Nadir Mapper (NM) onboard the Suomi National Polar Partnership (SNPP) spacecraft to analyze global changes of NO2 from 2012 to 2017. The largest decline of NO2 is detected in eastern China, at

Comparison of Instrument Calibration Performance for the SNPP ATMS and JPSS1 ATMS
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018The Advanced Technology Microwave Sounder (ATMS) is a microwave radiometer instrument designed, built, and tested by Northrop Grumman in Azusa, California. Data from ATMS is used in ground processing algorithms to produce atmospheric temperature and moisture profiles, as well as precipitation rates, snow and ice coverage.

Performance of the SNPP and NOAA-20 CrIS Sensor Data Record Products
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019In this work, the current performance of the calibrated Joint Polar Satellite System (JPSS) Cross-track Infrared Sensor (CrIS) observations is reported. The CrIS instrument is currently on-board the Suomi National Polar-orbiting Partnership (SNPP) and NOAA-20 spacecraft, and planned for the JPSS-2, -3 and -4 satellites.

Improvements in the calibration of the SNPP VIIRS day-night band (Conference Presentation)
Earth Observing Systems XXII, 2017We present improvements to the on-orbit calibration of the day-night band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi National Polar-orbiting Partnership (SNPP) satellite. Most important among the improvements is the expansion of the “sweet spot” from 4 o to 7.8o to increase the number of the fully illuminated scans for

Examination of the angular dependence of the SNPP VIIRS solar diffuser BRDF degradation factor
SPIE Proceedings, 2014Modern Earth-orbiting Earth-observing remote sensing sensors often use onboard solar diffusers (SD) to calibrate their reflective solar bands (RSB), such as the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi National Polar-orbiting Partnership (SNPP) satellite.

SNPP VIIRS thermal emissive band performance after three years on-orbit
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015The Suomi National Polar-orbiting Partnership (SNPP) spacecraft's primary sensor is the Visible-Infrared Imaging Radiometer Suite (VIIRS) which launched on October 28, 2011. It has 22 total bands with 7 thermal emissive bands (TEBs), a high dynamic range monochromatic Day Night Band (DNB) and 14 reflective solar bands (RSBs).
