VIIRS/JPSS2 Moderate Resolution Terrain Corrected Geolocation 6-Min L1 Swath 750m Light V002

The Visible Infrared Imaging Radiometer Suite (VIIRS) Moderate Resolution Terrain Correction Geolocation (VJ203MODLL) Version 2.1 product from the NOAA-21 VIIRS sensor is produced in 6 minute temporal satellite increments (swaths) at 750 meter resolution. Intersecting the VIIRS line of sight vector with Earth’s geoid and the World Geodetic System (WGS) ellipsoid, this product is based on the SRTM30 Version 2 digital elevation model (DEM), which uses GTOPO30 data for areas from 60° North to 60° South. VJ203MODLL is a terrain correction geolocation product that provides the spatial location for various VIIRS data products. Each swath of data is approximately 3,060 kilometers along track (long) and 3,060 kilometers across track (wide).

Provided in the VJ203MODLL product are variables for height, latitude, and longitude.

These Science Data Sets (SDS) variables are used in conjunction with the [VJ214](https://doi.org/10.5067/viirs/vj214.002) swath product for accurate geolocation information.

Known Issues
* The version for this product is listed incorrectly in the long name. The long name should read "VIIRS/JPSS2 Moderate Resolution Terrain Corrected Geolocation 6-Min L1 Swath 750m Light V021". This will be rectified in future versions.
