The Nighttime Microphysics RGB from GOES-16 ABI

The Nighttime Microphysics (NtMicro) RGB imagery provides multiple cloud characteristics of thickness, particle phase/size, and height within a single image in order to analyze cloud features. Below is an example of the NtMicro RGB from the full disk scans taken every 15 minutes.

The NtMicro RGB imagery (below) over Florida in the early morning of 3 March 2017 show a variety of clouds in the scene.  In southern Florida, various shades of aqua represent low, water clouds where surface observations indicated ceilings of 1000-1500 ft (MVFR conditions).  Slightly further north in central Florida, cloud tops are represented by more tan/yellowish coloring with the RGB representing thicker, colder clouds with larger particles.  This suggests clouds that are a bit higher above the ground.  Continuing northward the cloud features are seen streaming to the east, northeast.  These clouds have mostly dark coloring suggesting little contribution from all the color components (red, green, blue).  The purple clouds are thin, mid-level clouds with ice.  One can tell that the clouds are thin because the underlying surface (land vs water) influences the resulting shade of color as the cloud passes over.  The dark blue is very thin, cold cirrus clouds while the dark red represents similar cirrus clouds but with slightly thicker characteristics.  Also note that some bright red clouds appear over the Gulf Stream (right side of image) representing very thick, cold ice tops of convection.   Overall, quite a number of cloud features can be seen in this IR-based RGB in a very efficient product.
