NtMicro RGB Over N. Gulf

Low clouds and fog in the N. Gulf and Texas regions caused MVFR/IFR/LIFR conditions over a large area.  The VIIRS Nighttime Microphysics RGB shows aqua to gray coloring to represent these features.  In the RGB the scene is fairly complex with high and middle clouds (reds, blues, purples, tans …..).  The RGB composite uses the traditional 11-3.9um difference (seen below) and combines other channels to better illustrate the low cloud features between the middle/high clouds.  The RGB also improves the characterization of the thick, cold cloud tops associated with the cutoff low producing precipitation along the coast and southern states when compared to the simple 11-3.9um.  Other “microphysical” RGBs are possible during the day or in a form that can be applied both day and night (i.e. 24hr product).
