The pollution concentration and deposition data in the Search by Location tool has been updated and is now using 2016-2018 3-year mean data as of March 18th 2020.
The search by location tool can be used to provide concentrations, deposition, and critical loads and levels at a particular location throughout the UK. However, it should be remembered that retrieved data from a location search is based on much larger resolutions of 1 to 5 km. Searches can be made by using the OS Landranger series or by using the OS (x,y) grid (6 digit grid references are required). Postal code searches are not included as they are based on buildings, and not protected sites and biodiversity in the wider countryside.
