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

Variables are a set of physical properties whose values determine the characteristics or behavior of something. For example, temperature and pressure are variables of the atmosphere. Parameters and variables can be used interchangeably. Variable level attributes provide individual information for each variable.

The Name in this table is the variable name. Fill value indicates missing or undefined data points in a variable. Valid range is the range of values the variable can store. Scale factor is used to increase or decrease the size of an object and can be used to correct for distortion. For questions on a specific variable, please use the Earthdata Forum.
