For each monitoring site you can select hourly data or a range of pre-calculated basic statistics. The basic statistics are those which are relevant to each of the pollutant standards in the air UK Air Quality Strategy. Basic statistics are daily mean, maximum and minimum values, running 8-hour means (carbon monoxide and ozone only), and running 24-hour means (PM10 particulate matter only).

Data Output

There are three options for the output of the query, according to the size of the data request. Small enquiries can be shown on your screen using minimum HTML, moderately sized enquiries can be e-mailed to you as an attachment in comma separated format, or the largest enquiries will be left on an ftp site, also in comma separated format, for you to collect. The data on the ftp site will be wiped within seven days if it is not retrieved.

The comma-separated format should make it easy to load the file into a spreadsheet once saved to your local machine.
