MCIR--Colors the NOAA sensor 4 IR image using a map to color the sea blue and land green.
High clouds appear white, lower clouds gray or land/sea colored, clouds generally appear lighter, but
distinguishing between land/sea and low clouds may be difficult. Darker colors indicate warmer regions.
HVCT--Creates a false color image from NOAA APT images based on temperature using the HVC
color model. The HVC color model attempts to ensure that different colors at the same value will appear
to the eye to be the same brightness and the spacing between colors representing each degree will appear
to the eye to be similar. Bright areas are completely unsaturated in this model. Water appears blue
and with colors more indicative of land temperatures.
MSA--Multispectral analysis. Uses NOAA channel 2-4 image and determines which regions are
most likely cloud, land, or sea based on an analysis of the two images. Produces a vivid false-colored
image as a result. This enhancement does not use a palette nor is it temperature normalized.
