VIIRS/SNPP Cloud Mask and Spectral Test Results 6-Min L2 Swath 750m

Metadata Updated: August 9, 2018

The VIIRS Cloud Mask product is a Level-2 product generated at 750-m (at nadir) spatial resolutions. The algorithm employs a series of visible and infrared threshold and consistency tests to specify confidence that an unobstructed view of the Earth's surface has been observed. An indication of shadows affecting the scene is also provided. Radiometrically-accurate radiances are required, thus holes in the Cloud Mask will appear wherever the input radiances are incomplete or of poor quality assurance.

File Naming Convention:




ESDT = Earth Science Data Type or Shortname

YYYYDDD = Data acquisition year and Day-of-year per the Julian Calendar

HHMM = Hour and minute of acquisition

VID = Version ID of the data collection

YYYYDDDHHMMSS = Processing year, Day-of-year (Julian), UTC time (hour, minutes, seconds)

Format = File format suffix, which in the above case represents netCDF/HDF5
