Paper Abstract

The Visible/Infrared Imager Radiometer Suite (VIIRS) is one of the key instruments on the Suomi NPP and future JPSS missions, succeeding the legacy NOAA/AVHRR, EOS/MODIS, SeaWiFS, and DMSP/OLS as the new generation of operational imaging radiometer. With 22 spectral bands covering wavelengths from 0.41 to 12.5um, VIIRS provides data for the production of 25 Environmental Data Records (EDRs) with its calibrated and geolocated Sensor Data Records (SDRs). This paper provides an overview of NPP VIIRS postlaunch instrument performance, onboard and vicarious calibration/validation, as well as unique capabilities of the VIIRS and potential new applications. Since launch, the VIIRS SDR cal/val has been progressing well. Following a series of spacecraft and sensor activation and checkouts, the first VIIRS image was acquired on November 21, 2011, and all 22 bands have been producing early images by January 20, 2012. The data maturity has reached beta status in early spring of 2012, and provisional status is expected to be achieved by November 2012. Major challenges thus far include the unexpected fast degradation in some near infrared channels, and the unprecedented data volume and complexity of the ground processing system. Our goal is to ensure the radiometric, spectral, and geospatial accuracy, and establish consistency with past and future sensors to support the weather, climate, ocean, and other environmental applications.
