Subject:	OLI/TRACEGAS/M1 - Weekly displacement calibration of CO did not occur
Affected Datastreams:	oliaoscoM1.a1
Description	Some (minor) uncertainty in the calibration over this period. However, Calibrations before and after the event appear very stable. There are also daily standard additions between the weekly displacement calibrations. These daily checks are quite consistent. So this DQR is merely to notify of the condition. Data can be used with confidence in the judgment of the Mentor.

Subject:	OLI/TRACEGAS/M1 - Data output changed to 0.5 Hz
Affected Datastreams:	oliaoscoM1.a1
Description	In an effort to diagnoses data dropouts, the instrument output rate was changed from 1 Hz to 0.5 Hz. Since the instrument averages over the reported time and the dynamic time response is ~2-5 s, there is no appreciable loss in S/N or time response. Once tests are completed on the virtual machine and the LGR instrument, the reporting speed will be returned to 1 Hz.

Subject:	OLI/CO-ANALYZER/M1 - Reprocess: Valve position fields incorrect
Affected Datastreams:	oliaoscoM1.b1
Description	A bug in the a1- and b1-level AOS CO ingest processes caused the valve position fields to be incorrect. This had the trickle-down effect of flagging the primary fields as incorrect via embedded QC in the b1-level product. Reprocessing is being requested now that this ingest bug has been corrected.
