2-D Lunar Microwave Radiance Observations From the NOAA-20 ATMS
IEEE Geoscience and Remote Sensing Letters, 2021Reported here are disk-integrated Moon surface microwave brightness temperature ( $Tb$ ) retrievals covering the frequency range of 23–183 GHz. Full Moon observations obtained from the advanced technology microwave sounder (ATMS) onboard the NOAA-20 satellite during a special spacecraft pitch–maneuver operation forms the basis of the retrievals ...

Crosstalk Effect in NOAA 20 VIIRS Thermal Emissive Bands
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Crosstalk contamination in the Moderate Resolution Imaging Spectroradiometer (MODIS) thermal emissive bands (TEBs) has been a known issue since prelaunch, that has amplified on-orbit for some of bands. A linear algorithm has been developed and successfully applied to mitigate the crosstalk effect and restore the quality and accuracy of the MODIS L1B ...

NOAA-20 VIIRS reflective solar bands on-orbit calibration
Sensors, Systems, and Next-Generation Satellites XXIII, 2019The NOAA-20 Visible Infrared Imager Radiometer Suite (VIIRS) has been in orbit for more than one and a half years. VIIRS has 22 bands, among which 14 are reflective solar bands (RSBs) covering a spectral range from 0.410 to 2.250 μm. The RSBs are calibrated on-orbit using an onboard solar diffuser (SD), whose on-orbit degradation is tracked by an ...

Radiometric performance characterization of NOAA-20 VIIRS reflective solar bands
Earth Observing Systems XXV, 2020NOAA-20 VIIRS Reflective Solar Bands (RSBs) have been performing well since launch with good quality sensor data records (SDRs). The radiometric performance of these SDRs have been continuously analyzed and monitored using various independent validation techniques. It is important to maintain radiometric consistency between NOAA-20 VIIRS SDRs and other

NOAA-20 VIIRS On-Orbit Calibration and Performance Update
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Launched in November 2017, the NOAA-20 (N-20) VIIRS has successfully completed more than 1.5 years of on-orbit operations. In addition to initial post-launch check-outs followed by a series of intensive calibration and validation activities, the instrument performed a mid-mission outgassing in March 2018 to remove the ice buildup on the dewar window of

Spectral Calibration of NOAA-20 OMPS Sensor Data Record
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019The NOAA-20 Ozone Mapping and Profiler Suite (OMPS) is one of the five instruments in the US Joint Polar Satellite System (JPSS) program. Like the first OMPS instrument [1],[2], the N20 OMPS contains two advanced nadir viewing hyper-spectral instruments, the Nadir Profiler and the Nadir Mapper, to track the health of the ozone layer via measurements ...

Performance assessment of the NOAA-20 VIIRS RSB using deep convective clouds
Earth Observing Systems XXVI, 2021The Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the NOAA-20 (N20) satellite was launched on November 18, 2017. The N20 VIIRS reflective solar bands (RSBs) are calibrated on-orbit using a solar diffuser. An accurate on-orbit calibration is crucial to the high-quality downstream products facilitating atmosphere, ocean and land applications.

Initial calibration activities and performance assessments of NOAA-20 VIIRS
Earth Observing Missions and Sensors: Development, Implementation, and Characterization V, 2018The second VIIRS instrument was launched on-board the NOAA-20 (formerly JPSS-1) satellite onNovember 18, 2017. It was designed and built with the same performance requirements as the first VIIRSon-board the S-NPP launched on October 28, 2011. Currently, the NOAA-20 is orbiting the Earth in thesame plane as the S-NPP but separated in time and space by ...
