Note 1: The results are based on the new daily air quality index which is in use from the 1st of January 2012. |
Note 2: All results from TEOM PM10 analysers from 2004 onward are
now converted to reference equiavlence using the volatile correction method. |
Note 3: This information is calculated twice daily, so may not reflect the latest data.
