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

Unusable

Out2 showed AMF dependence and Ous1 columns were slightly offset from reference

O3Synt

Decision for O3Synt

With Care

NO2

Decision for NO2

Yes

E-MLE, NO2 columns and wrms shape looks good and agree well with Ref instrument

SO2

Decision for SO2

With Care

MLE, SO2 columns agree somewhat with reference but show stronger AMF shape

HCHO

Decision for HCHO

Yes

E-MLE, HCHO columns and wrms shape looks good and agree well with Ref instrument

H2O

Decision for H2O
