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

Calibrated using ref method (P2). Both out2 and ous1 column and wrms shapes look good

O3Synt

Decision for O3Synt

NO2

Decision for NO2

Calibrated using ref method (P2).Rms is a more noisy than typically, but shape looks good

SO2

Decision for SO2

Calibrated using ref method (P2). Both column and wrms shapes look good

HCHO

Decision for HCHO

Calibrated using ref method (P2). Lots of scatter in columns, but values still look good when compared with sky data

H2O

Decision for H2O

Columns follow sky data nicely, and good rms shape
