Hi Folks.
I'm trying to navigate the Defra site to get to where I can use the 3 criteria above, to enter a post code and year and find the mean level for a pollutant for that place and time.
It's a long shot, but does anybody know of the exact way of getting that information, there's a maze of things to experiment with on the Defra site, and it's taken ages. (!)
Many thanks.
Tim
