VIIRS - Level-0 and Level-1
The VIIRS Level-1 software and data products largely follow the model previously developed for MODIS.
The software includes separate executable modules for Level-1A, Geolocation, Onboard Calibrator (OBC) and Level-1B processing.
The interfaces between the software modules are the data products. Specifically, the Level-1A product is the input to the Geolocation, Level-1B and OBC software.
The nominal granule size is longer than the NOAA VIIRS granules (85.35 seconds). The standard granule period is 6 minutes, but the software will be capable of processing any reasonable granule period.
