Updating CBED modelling data & new Source Attribution Data

Updating CBED modelling data

We've updated the Search by Location and Site Relevant Critical Loads tools to use the latest pollutant deposition and concentration data. They are now based on a 3-year mean for 2012-2014. Remember that you can also view the changes in concentration/deposition since 2005 at each protected site.

New Source Attribution Data

We’ve updated the source attribution data in the Site Relevant Critical Loads tool. The total acid and nitrogen deposition at each site is apportioned between sources. We also now show the extent to which deposition is from local sources or distant sources. This information can help assess where to target measures to reduce deposition at sites.
