This version is considerably faster and all the known bugs have been corrected. The “Results” tab has changed with new features. The APIS data for the midyear 2019 (2018, 2019 and 2020) has been released with this new version now  at 1 km2 resolution (previously 5 km2). You will also be able to query Source Attribution data for any grid square of the UK and we have also added a Critical Loads Screening tool for acidity.
