These are the historical satinfo files that should be used with retrospective 
FV3 Beta runs.  Dates refer to the first cycle for which the file should be used.

global_satinfo.txt is the base satinfo file, i.e., the one that should be 
implemented (at least until CrIS and ATMS from N20 are turned on). Differences in this file relative to current operations are:

AMSUA Ch 15 (all satellites): error_cld increased to 18.0 from 15.0
Turn on IASI water vapor channels 2889, 2958, 2993, 3002, 3049, 3105, 3110, 5381, 5399, 5480
Switch off AMSU-A Aqua channel 6 
ATMS switched to cloudy radiances (channel 1-7, 16-22)
CrIS_NPP replaced with CrIS-FSR_NPP
Turn on Saphir

global_satinfo.txt.2018021212 is a copy of global_satinfo.txt

global_satinfo.txt.2017103118 replaces CrIS-FSR_NPP with CrIS_NPP (aka CrIS NSR)
