New APIS Tool
A new APIS GIS map tool for Site Relevant Critical Loads & Search by Location has been developed in place of the look-up system below. For the first time we have added 1km datasets for Ammonia and N and Acid Deposition.
Note on the new 1km data (2018-2020): To calculate the pollutant maps for Ammonia, Nitrogen and Acid Deposition we are now using a new transport model (EMEP4UK) to calculate the ammonia footprint for the UK. This output is then calibrated to our ammonia measurement network data. You will notice some spatial changes in concentrations and depositions across the UK. In general the change has meant some elevated concentrations between the 1-3 ug/m3 range, but large parts of the UK have remained unchanged. A full report on the analysis of the change in model will be released soon and shared on APIS.
We welcome any comments or suggestions that you may have about the new APIS interface, you can suggest your changes or report any problems and select the option "APIS bugs & broken links".
To see a video demonstration on how to use this tool go here.
If you wish to keep using the look-up tables below then we are making that available until the new tool 'beds in'.
