* Note that all objectives have been calculated using a method defined in 2013.
* Note that these results cover from the start of the year to now, and are still subject to change until the end of the year. Figures for the current year do not take data capture rate into account.
* 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.
