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

AXC-T clim: 232K calculated: 238K. Both O3 products showed a little bit of AMF dependent shape, and out2 wrms slightly above limits

O3Synt

Decision for O3Synt

With Care

NO2

Decision for NO2

Yes

E-MLE. NO2 columns matched REF instrument well and no noticeable wrms shape

SO2

Decision for SO2

Yes

E-MLE. SO2 columns matched REF instrument well

HCHO

Decision for HCHO

Yes

E-MLE. HCHO columns matched REF instrument well

H2O

Decision for H2O
