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

O3T appr.15° above climatology. but shape of T and vc are as expected

O3Synt

Decision for O3Synt

With Care

NO2

Decision for NO2

Yes

looks okay

SO2

Decision for SO2

With Care

sometimes negative

HCHO

Decision for HCHO

With Care

get flagged during winter months - refday in sept tried to account winter ref

H2O
