SCAIL - Combustion 

June 11th, 2024: SCAIL background pollution maps for the UK have been updated to the the years 2020-2022 in line with current APIS (see announcement). We have also introduced a new Hybrid mode for users (see User Guide for details of how to use it).


Simple Calculation of Atmospheric Impact Limits from Combustion Sources (SCAIL-Combustion) is a screening tool for assessing the impact from combustion plant on semi-natural areas like SSSIs and SACs. The model provides an estimate of the amount of acidity, nitrogen and sulphur deposited on a habitat from the combustion source. This value can then be used to assess whether impact limits for the habitats are exceeded or not.
