DESCRIPTION OF CHANGES: This PR addes the assimilation of GOES-16/17 ABI's 3 water vapor channels' radiance data. This includes reading of ABI's full-disk, CONUS, and meso1&2 data files, superobbing and thinning of ABI data, IR-based cloud detection scheme as part of quality control, and all-sky obs error model. Cloud detection scheme should be the same as for AHI in principle, but the actual code implementation is not the same. No attempt made to make ABI's cloud detection code consistent with AHI's when bringing the code originally developed back in 2019-2020 into the latest develop branch. Some technical information is provided below for the use of this new capability.
ABI data reading code will automatically determine which file(s) to read in matching ABI file's time and analysis time.
Cloud detection scheme needs to read in a terrain file OR_ABI-TERR_G16.nc or OR_ABI-TERR_G17.nc for GOES-16 ABI or GOES-17 ABI.
