Manual review and decision

Manual Review and Decision

Calibration notes, data-quality findings, and whole-period evaluation.

Data Evaluation

Could there be an offset between VPs?

Are there breakpoint-analysis plots or suspicious discontinuities?

Do daily figures before and after the new VP look consistent?

Is there an AMF dependency for one or more VPs?

Is there seasonality, for example negative values in winter?

Does the daily shape follow the trop data roughly?

If there is a discrepancy, what are the DS and Sky viewing directions?

Is there a co-located or nearby instrument for comparison?

O3Ext

Decision for O3Ext

With Care

AXC worked good, high uncertainty for AXC-T

O3Synt

Decision for O3Synt

Unusable

NO2

Decision for NO2

Yes

only standard MLE

SO2

Decision for SO2

Unusable

strong SO2 event, but the at higher AMFs the columns become negative

HCHO

Decision for HCHO

With Care

second VP is properly flagged but not enough days to calibrate it properly

H2O

Decision for H2O
