Feature/jjin3/allsky mw cloud retrieval qc flag #137

Closed gmao-jjin3 closed 1 year ago

gmao-jjin3 commented 1 year ago

Add a qc_flag of failed microwave cloud function using simulated brightness temperature (Tb) in all-sky DA. Observation should be tossed out when cloud amount cannot be derived from observed Tb or simulated Tb, but current GSI fails in doing that. See the note: https://github.com/GEOS-ESM/swell/issues/66#issuecomment-1224173465

A failure in cloud function using observed Tb or simulated Tb results in the observation being tossed in JEDI/UFO. Therefore, this PR would make this QC identical in GSI and JEDI though impact in final analysis is likely trivial.
