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?
