The number of ambient limit value exceedances,
red marked exceeded the ambient limit value

calculated of both operational data (yet unverified) and verified data

Updated: 2024-11-21 03:15 CET

The values are from all active stations regardless of whether the number of valid measurement meets the criteria for calculating the aggregated data (annual average).

For the completeness and quality of data is responsible the data supplier, not the CHMI.

Completeness of data – completeness of measured data supplied to AQIS database to the day of table update (in percentage).
