Infrared radiance analysis from the SNPP airborne field campaign
SPIE Proceedings, 2014Experimental field campaigns, including satellite under-flights with well-calibrated FTS sensors aboard high-altitude aircraft, are an essential part of the satellite measurement system validation task aimed at improving observations of the Earth’s atmosphere, clouds, and surface for enabling enhancements in weather prediction, climate monitoring ...

SNPP VIIRS spectral response lessons learned and their impacts on JPSS VIIRS performance
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015A primary sensor on-board the Suomi-National Polar-orbiting Partnership (SNPP) spacecraft, the Visible Infrared Imaging Radiometer Suite (VIIRS) has 22 bands: 14 reflective solar bands (RSBs), 7 thermal emissive bands (TEBs) and a Day Night Band (DNB).

Intercomparison of the SNPP and NOAA-20 VIIRS DNB High-Gain Stage Using Observations of Bright Stars
IEEE Transactions on Geoscience and Remote Sensing, 2020The Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi-NPP (SNPP) and NOAA-20 (N20) spacecrafts is a multispectral Earth-observing instrument with bands covering wavelengths from visible to long-wave infrared.

RSB calibration of SNPP VIIRS using solar diffuser illuminated by scattered light
Earth Observing Systems XXII, 2017We present a new variant to the on-orbit calibration methodology for the reflective solar bands (RSBs) of SNPP VIIRS using solar diffuser (SD). Instead of following the standard method using full solar illumination through SD port that occurs during terminator crossing, we use light scattered off Earth scenes coming through the nadir port as the source

Positional dependence of the SNPP VIIRS SD BRDF degradation factor
Sensors, Systems, and Next-Generation Satellites XXI, 2017The Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi National Polar-orbiting Partnership (SNPP) satellite is a passive scanning radiometer and an imager. The VIIRS regularly performs on-orbit radiometric calibration of its reflective solar bands (RSBs) through observing an onboard sunlit solar diffuser (SD).

Electronic crosstalk effect in SNPP VIIRS thermal emissive bands (Conference Presentation)
Earth Observing Systems XXII, 2017The Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership (SNPP) spacecraft has been on orbit for more than five years. Pronounced striping in Earth view (EV) images and obvious discontinuity in the EV brightness temperature (BT) of the thermal emissive bands (TEB) during the blackbody (BB) warm-up ...

The curious case of the intersensor radiometric comparison of SNPP VIIRS M11 with Aqua MODIS B7
Earth Observing Systems XXII, 2017The inter-sensor radiometric comparison of the 2257 nm channel (M11) of SNPP VIIRS and the 2130 nm channel (B7) of Aqua MODIS curiously demonstrates a wildly varying time series, in stark contrast to the very stable results of other band pairs. A link is found between the few statistically robust outcomes in the time series and the land-based snowy ...
