The VIIRS instrument was launched on the NASA/NOAA Suomi NPP satellite in October 2011. This instrument is the first of a series of VIIRS instruments meant to continue the operational and long-term measurements of NASA, NOAA and DOD heritage instruments such as the MODIS instruments on the NASA EOS Terra and Aqua satellites and other. The VIIRS Sensor Data Record product recently achieved Beta Maturity...
Accurate geolocation of remote sensing data is vital to all aspects of Earth science research and applications, especially over heterogeneous land surfaces. To achieve and maintain accurate geolocation throughout multi-year missions, an initial on-orbit bias removal is followed by analysis and removal of the long term trends in the instrument pointing caused by temporal changes in the instrument and...
The Land Product Evaluation and Algorithm Testing Element (Land PEATE), a component of the Science Data Segment of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP), is being developed at the NASA Goddard Space Flight Center (GSFC). The primary task of the Land PEATE is to assess the quality of the Visible Infrared Imaging Radiometer Suite (VIIRS)...
