Volatile Correction Model

Start your correction

The volatile particulate matter concentration varies geographically and temporally; information on the site location, and averaging time are therefore required for the valid operation of the model. Please have these ready before you start.

After downloading the relevant spreadsheet, paste in your own measurements. The spreadsheet will then calculate the gravimetric reference equivalent PM10 concentrations. More detailed help and advice is provided as you progress through the portal.
