Boundaries

Reliability, caveats, and privacy

What held up

Source measurement time is supplied per value
Five station objects returned for Tbilisi
Coordinates and stable-looking station codes support joins
Last-known values can be cached with original timestamps

What can go wrong

Automatic observations are provisional until verified
Some English/localized fields are empty or remain Georgian
A station or pollutant series can be empty/delayed
Pollutant units differ; CO used mg/m³ in the sample
