SNPP/VIIRS Vegetation Health to Assess 500 California Drought [PDF]
Geomatics, Natural Hazards and Risk, 2017 Beginning in 2006, western United States was affected by a 11-year strong mega-drought. Among 17 western states, California was the most severely drought-affected during 2012–2015, when an area of stronger than moderate vegetation stress reached 70%. This drought had considerable impact on California's environment, economy and society.

On-orbit measurement of the focal length of the SNPP VIIRS instrument
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument is a whiskbroom system with 22 spectral bands split between 16 moderate resolution bands (M-bands), five imagery resolution bands (I-bands) and a panchromatic day-night band. Latitude and Longitude geolocation data are generated for each pixel at the M-band, I-band and day-night band ...

On-orbit noise characterization of the SNPP VIIRS reflective solar bands
Earth Observing Systems XXII, 2017The Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi National Polar-orbiting Partnership satellite has 14 reflective solar bands (RSBs) covering a spectral range from 410 nm to 2250 nm. We provide an overview of the noise characterization of the VIIRS RSB from pre-launch through more than five years of on-orbit operation.

AFPEP - SNPP - L’autorité en psychiatrie
French Journal of Psychiatry, 2019Le theme de l’autorite, loin de ne concerner que l’education, la justice ou la politique auxquelles on l’associe souvent, interroge aussi le champ de la sante, et en particulier le domaine de la psychiatrie. Si l’autorite ne figure pas a proprement parler parmi les concepts classiques de la philosophie, les notions de pouvoir et d’obeissance, qui lui ...

Assessment of on-orbit crosstalk impact for SNPP VIIRS VisNIR bands
SPIE Proceedings, 2014Electronic and optical crosstalk is one of the major challenges facing space-based Earth observing sensors, the effects of which could pose serious risks to the successful retrieval of geophysical information. There was an extensive effort during the SNPP VIIRS design and testing phase to characterize the on-orbit VisNIR crosstalk and its impact on ...
