satpy.readers.viirs_l2 module

Interface to VIIRS L2 format.

This reader implements the support of L2 files generated using the VIIRS instrument on SNPP and NOAA satellite files. The intent of this reader is to be able to reproduce images from L2 layers in NASA worldview with identical colormaps.

Currently a subset of four of these layers are supported 1. Deep Blue Aerosol Angstrom Exponent (Land and Ocean) 2. Clear Sky Confidence 3. Cloud Top Height 4. Deep Blue Aerosol Optical Thickness (Land and Ocean)
