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

AXC-T estimated O3T was 6K higher than climatology. Out2 had strong AMF dependence and wrms was above limits for entire day. Ous1 columns looked OK

O3Synt

Decision for O3Synt

With Care

NO2

Decision for NO2

Yes

EMLE, columns looked good and matched REF instrument. No obvious shape in wrms structure

SO2

Decision for SO2

Yes

EMLE, columns looked good and matched REF instrument

HCHO

Decision for HCHO

Yes

EMLE, columns looked good and matched REF instrument

H2O

Decision for H2O
