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

Yes

interpolation used in AXC

O3Synt

Decision for O3Synt

Yes

NO2

Decision for NO2

Yes

MLE used, looks good

SO2

Decision for SO2

With Care

looks good

HCHO

Decision for HCHO

With Care

some days have double values in HCHO SC and wrms due to unknown hardware issues

H2O

Decision for H2O

Yes

looks good.
