ADMS-Airport is a comprehensive tool for managing air quality at airports. It is an extension of the ADMS-Urban model, designed to model the concentration of pollutants at airports in rural or complex urban environments.
ADMS-Airport has been used to model air quality at London's Heathrow airport for the 2002 base case and future year scenarios as part of the Department for Transport's (DfT) Project for Sustainable Development of Heathrow (PSDH)—Adding Capacity at Heathrow.
ADMS-Airport is also one of the participating models in the International Civil Aviation Organisation, Committee on Aviation Environmental Protection (ICAO CAEP) model exercises.
