The project developed a sound understanding of the processes of mixing and transport from the street-level into the boundary-layer. It also developed methods for parameterising these processes in urban-scale dispersion models and in numerical weather prediction models through an urban canopy model of urban areas.","keywords":"URGENT, URBMET, Chemistry, Pollutants, Air pollution,","status":"completed","publicationState":"published","identifier_set":[],"observationCollection":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/2871/?format=json"],"parentProject":"https://catalogue.ceda.ac.uk/api/v2/projects/2402/?format=json","subProject":["https://catalogue.ceda.ac.uk/api/v2/projects/14214/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/55254/?format=json"]}
