Progress in the calibration/validation of VIIRS on Suomi NPP and J1

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
This paper presents the recent progress in the cal/val of the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi National Polar Orbiting Partnership (NPP) since launch, and Joint Polar Satellite System (JPSS) J1 which will be launched in 2017. The Suomi NPP VIIRS instrument continues to perform well with a very stable calibration according to ...

Update on the performance of Suomi-NPP VIIRS lunar calibration

SPIE Proceedings, 2015
Lunar observations have been regularly scheduled for the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite since its launch on October 28th, 2011. In reference to the ROLO irradiance model, the detector gain coefficient or F-factor can be derived from these lunar ...

A global Precipitation retrieval algorithm for Suomi NPP ATMS

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
This paper develops a precipitation retrieval algorithm for the Advanced Technology Microwave Sounder (ATMS) recently launched aboard the U.S. Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. The algorithm is called the ATMS MIT Precipitation retrieval algorithm version 1 (ATMP-1), employs neural network estimators trained and evaluated

Suomi-NPP Inclination Adjustment Maneuver Campaign

AIAA SPACE 2015 Conference and Exposition, 2015
Suomi National Polar-orbiting Partnership (NPP), a satellite with only posigrade thrusters, performed a series of Inclination Adjustment Maneuvers (IAM) in 2014. Prior to performing these maneuvers, a redesign of the lifetime Mean Local Time at the Ascending Node (MLTAN) profile was required as well as improving attitude performance compared to what ...

Suomi NPP VIIRS Day-Night Band On-Orbit Performance [PDF]

Journal of Geophysical Research D: Atmospheres, 2013
AbstractThe Suomi National Polar‐Orbiting Partnership (NPP) launched on 28 October 2011 hosts the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor. The VIIRS sensor includes a day‐night band (DNB) that covers almost 7 orders of magnitude in its dynamic range from full sunlit scenes to lunar‐illuminated clouds. The DNB is panchromatic and covers

Suomi-NPP VIIRS unscheduled lunar observations

SPIE Proceedings, 2016
Lunar observations by the Suomi-NPP instrument VIIRS are scheduled on a nearly monthly basis at a phase angle of approximately -51 degrees. The lunar images acquired during scheduled observations have been used for radiometric calibration stability monitoring of the reflective solar bands, band-to-band registration characterization, modulation transfer

Suomi-NPP VIIRS day/night band calibration with stars

SPIE Proceedings, 2015
Observations of stars can be used to calibrate the radiometric performance of the Day/Night Band (DNB) of the Suomi-NPP instrument VIIRS. Bright stars are normally visible in the Space View window. In this paper, we describe several potential applications of stellar observations with preliminary results for several.

SUOMI NPP VIIRS reflective solar band radiometric calibration

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Visible-Infrared Imaging Radiometer Suite (VIIRS) is a primary sensor onboard the National Polar-orbiting Partnership (NPP) satellite launched on October 28, 2011. It collects data over the spectral range of 0.4–12.5 um and consists of 15 reflective solar bands (RSB) and 7 thermal emissive bands (TEB).

SUOMI NPP VIIRS emissive band radiance calibration and analysis

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
VIIRS thermal emissive bands (TEB) have been analyzed. The analysis results indicate the VIIRS TEB is stable and exceeds the specification. Comparisons between the VIIRS and other sensors such as AVHRR, MODIS and CrIS demonstrated that VIIRS TEB agrees well with those sensors. Using Community Radiative Transfer Model (CRTM), developed at U.S.
