Polish Air Quality Index for a Monitoring Station: Current Level and Pollutant Sub-Indexes (GIOŚ)

gios/station-air-quality-index

The current Polish air quality index of one monitoring station (from its id): an overall index value and category (Polish names such as Bardzo dobry, very good) and a sub-index with category for each of SO2, NO2, PM10, PM2.5 and O3, each with the time it was computed and the time of the source measurement, in local time. Recomputed hourly. A station id GIOŚ does not know returns a record with every field null rather than an error, and a pollutant the station does not measure has null fields. Find ids with the station list. The response keeps GIOŚ's own Polish field names. GIOŚ notes the data are not verified on an ongoing basis and may change later.
