The geostationary advanced baseline imager on GOES-17 (west) is susceptible to the
Loop-Heat-Pipe (LHP) issue. As a result, the images in some GOES-17 ABI channels
are degraded at certain times of day, and certain times of the year when the cooling
system isn’t able to radiate enough of the sun’s energy properly. NOAA has compared
the mean value in a region of interest over the equator between the two satellites
(GOES-16 and GOES-17). We have been able to reproduce these results. This
research extends the analysis by evaluating histogram matching as a means to quantify
the change in the brightness temperature histogram due to the LHP heating. In addition
we will evaluate the application of an empirical mapping function as a means of
compensating for errors in the apparent brightness temperature.
