Provisional Pollutant Data with Limited Validation

All air pollutant concentration data from the air quality monitoring stations will be uploaded to the Environmental Protection Interactive Centre (EPIC) for free download after validation by quality assurance and control procedures.

Since the complete validation process takes about three months, you can download the data in the last few months here with preliminary limited validation. Please note that the data has not been fully validated and for reference only.
