Subject:	OLI/OZONE/M1 - Calibration varied unexpectedly
DataStreams:	oliaoso3M1.a1, oliaoso3M1.00, oliaoso3M1.01
Description:	The calibration response showed a decrease and then recovered. The decrease was about 10%. It is not clear what this was due to. The instrument sensitivity COULD have varied by the same amount, but this isn't clear. AMF3 AOS experienced temperature swings during this period that may have affected the O3 standard or the O3 photometer or both. Given the low ambient concentrations, a 10% reduction in response would be almost indetectable, hence the transparent categorization.
