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

Some days of O3Ext and O3Synth have inverse u-shape, due to AMF dependency.

O3Synt

Decision for O3Synt

Yes

NO2

Decision for NO2

Yes

looks okay, no tropdata available thus MLE used.

SO2

Decision for SO2

Yes

some days have wiggly daily cycle

HCHO

Decision for HCHO

Unusable

delrin period

H2O

Decision for H2O

Yes
