Using Ground Targets to Validate S-NPP VIIRS Day-Night Band Calibration [PDF]

Remote Sensing, 2016
In this study, the observations from S-NPP VIIRS Day-Night band (DNB) and Moderate resolution bands (M bands) of Libya 4 and Dome C over the first four years of the mission are used to assess the DNB low gain calibration stability. The Sensor Data Records produced by NASA Land Product Evaluation and Algorithm Testing Element (PEATE) are acquired from ...

Performance Monitoring of the S-NPP Ozone Mapping and Profiler Suite’s Sensor Data Records

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
Launched on October 28, 2011, the S-NPP satellite carried an ozone mapping and profiler suite (OMPS) of sensors. OMPS opened its aperture door on January 26, 2012 to begin its Earth observation mission. After an early orbit checkout of the sensors for a couple of months and an intensive evaluation of the sensor data for several more months, an initial ...
