* Note that all objectives have been calculated using a method defined in 2013.
* Note that results are excluded where analysers have not returned valid data for at least 90% of the year, unless a short-term objective was exceeded.
* Note - all results from TEOM PM10 analysers from 2004 onward are now converted to reference equivalence using the volatile correction method. Results using the old 'TEOM*1.3' method are also shown for comparison where relevant. More information.
* Note that this information is calculated twice daily, so may not reflect the latest data.
