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

O3Synt looks good, O3Temp inverse-u shaped / M-shaped, seasonal O3Temp change. O3Ext almost everything flagged out

O3Synt

Decision for O3Synt

With Care

NO2

Decision for NO2

With Care

high scatter and temporal offset to sky data, used REF method with data from v17

SO2

Decision for SO2

Yes

used REF method with data from v17

HCHO

Decision for HCHO

With Care

E-MLE used

H2O

Decision for H2O

Yes
