Suomi-NPP VIIRS Solar Diffuser Stability Monitor Performance

IEEE Transactions on Geoscience and Remote Sensing, 2016
When illuminated by the Sun, the onboard solar diffuser (SD) panel provides a known spectral radiance source to calibrate the reflective solar bands of the Visible Infrared Imaging Radiometer Suite on the Suomi-NPP satellite. The SD bidirectional reflectance distribution function (BRDF) degrades over time due to solar exposure, and this degradation is ...

First-Light Imagery from Suomi NPP VIIRS

Bulletin of the American Meteorological Society, 2013
The Suomi National Polar-Orbiting Partnership (NPP) satellite was launched on 28 October 2011, heralding the next generation of operational U.S. polar-orbiting satellites. It carries the Visible– Infrared Imaging Radiometer Suite (VIIRS), a 22-band visible/infrared sensor that combines many of the best aspects of the NOAA Advanced Very High Resolution ...

A simplified Suomi NPP VIIRS dust detection algorithm

Journal of Atmospheric and Solar-Terrestrial Physics, 2017
Abstract Due to the complex characteristics of dust and sparse ground-based monitoring stations, dust monitoring is facing severe challenges, especially in dust storm-prone areas. Aim at constructing a high-precision dust storm detection model, a pixel database, consisted of dusts over a variety of typical feature types such as cloud, vegetation ...

Early orbit operations performance of the Suomi NPP OMPS instrument

SPIE Proceedings, 2012
The Ozone Mapping Profiler Suite (OMPS) was launched aboard the Suomi National Polar-orbiting Partnership (Suomi NPP) spacecraft on October 28, 2011. OMPS is meant to continue NOAA/NASA's long-term ozone data record and bridge the gap to the Joint Polar Satellite System (JPSS) missions later this decade.

Overview of Suomi NPP VIIRS performance in the last 2.5 years

SPIE Proceedings, 2014
Since the successful launch of the Suomi NPP on October 28, 2011, the VIIRS instrument has performed well in general. This paper provides an overview of the evolution of the VIIRS instrument performance, major events experienced in the nearly three years since launch, and the ground processing system changes to account for various effects and ...

Reprocessing of SUOMI NPP VIIRS sensor data records and impacts on environmental applications

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
This study describes the improved calibration applied for VIIRS SDR reprocessing. At reflective solar bands (RSBs), the earth-view F-factor is adjusted with the lunar observations and changes about 2% in band M2-M4 in past five years. An empirical method is applied to remove the radiance spikes in VIIRS thermal emissive bands (TEBs) during the ...

Radiometric performance assessment of Suomi NPP VIIRS SWIR Band (2.25 μm)

SPIE Proceedings, 2015
Suomi NPP VIIRS SWIR band M11 (2.25 μm) has larger radiometric uncertainty compared to the rest of the reflective solar bands. This is due to a number of reasons including prelaunch calibration uncertainties. One of the most commonly used technique to verify the radiometric stability and accuracy of VIIRS is by intercomparing it with other well ...

Application of suomi-npp/viirs data in near real time flood detection

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
As the costliest natural disaster over the globe, floods are predicted to become more frequent in most climate change forecasts. In high latitudes, floods are caused by ice jam and snow melt almost every break-up season. Floods caused by intense rainfall also threaten lives and social infrastructures.

Estimating the characteristics of sub-pixel fires using Suomi-NPP VIIRS data

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
The characteristics of sub-pixel fires in Suomi-NPP VIIRS data are studied using the Nightfire algorithm which attempts to fit the spectral radiance to a blackbody function. For small and/or low intensity fires, the fire temperature tends to be underestimated while the fire area are overestimated.

Suomi NPP VIIRS solar diffuser screen transmittance model and its applications

Applied Optics, 2017
The visible infrared imaging radiometer suite on the Suomi National Polar-orbiting Partnership satellite calibrates its reflective solar bands through observations of a sunlit solar diffuser (SD) panel. Sunlight passes through a perforated plate, referred to as the SD screen, before reaching the SD.
