Description
Product Title: Visible Infrared Imager-Radiometer Suite NPP Level-2 The Visible and Infrared Imager/Radiometer Suite (VIIRS) is a multi-disciplinaryinstrument that is being flown on the Joint Polar Satellite System (JPSS) series ofspacecraft, including the Suomi National Polar-orbiting Partnership (S-NPP) thatlaunched in October 2011. JPSS is a multi-platform, multi-agency program thatconsolidates the polar orbiting spacecraft of NASA and the National Oceanic andAtmospheric Administration (NOAA). S-NPP is the initial spacecraft in this series,and VIIRS is the successor to MODIS for Earth science data product generation. VIIRShas 22 spectral bands ranging from 412 nm to 12 nm. There are 16 moderate-resolutionbands (750m at nadir), 5 image-resolution bands (375m), and one day-night band (DNB).

Variables
The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.
For questions on a specific variable, please use the Earthdata Forum.
