VIIRS/NOAA20 Cloud Mask 6-Min L2 Swath 750m V2

The v2.0 collection, which starts from February 17, 2018 (2018-048), also contains a high-resolution I-band (375 m) daytime cloud mask. The L2 netCDF product, acquired and processed every 6 minutes, contains two sets of the following three data groups and Science Data Set (SDS) layers in each group: | Geophysical data | Geophysical data (I-band Hi-res) | | :--- | :--- | | VIIRS Clear-Sky Confidence | VIIRS Clear-Sky Confidence | | VIIRS Cloud Mask and Spectral Results | VIIRS Cloud Mask and Spectral Results | | Cloud Mask SPI | | | VIIRS Integer Cloud Mask | VIIRS Integer Cloud Mask | | Quality Assurance for VIIRS Cloud Mask | Quality Assurance for VIIRS Cloud Mask | | Geolocation data | Geolocation data (I-band Hi-res) | | Latitudes of pixel locations | Latitudes of pixel locations | | Longitudes of pixel locations | Longitudes of pixel locations | | Sensor azimuth at pixel locations | Sensor azimuth at pixel locations | | Sensor zenith at pixel locations | Sensor zenith at pixel locations | | Solar azimuth at pixel locations | Solar azimuth at pixel locations | | Solar zenith at pixel locations | Solar zenith at pixel locations | | Scanline attributes | Scanline attributes (I-band Hi-res) | | Scan start-time (TAI93) | Scan start-time | | | | Consult the MODIS-VIIRS Cloud Mask Product User Guide for additional information regarding the transition from the MODIS-MOD35 to the MVCM algorithm, inputs to MVCM, output files, file naming conventions, quality flags, and validation.

Users are also encouraged to consult the MOD35 Algorithm Theoretical Basis Document (ATBD) and the MODIS Atmosphere QA Plan for relevant information that are applicable to the NOAA-20 VIIRS Cloud Mask product.
