APPRAISE-ADIENT
ADIENT is a consortium of the UK’s APPRAISE aerosol programme led by the University of Oxford. In this project we will use an aircraft jointly to make measurements of aerosol properties (such as size and composition) in two different UK campaigns + ADIENT-PLUME: Six flights will be performed over the North Sea in plumes downwind of UK cities to measure the evolution of aerosol particles + ADIENT-BUDGET: Six flights will be carried out mapping the impact of the UK sources on regional aerosol. In addition, three flights will be made in still conditions which favour the build up of aerosol pollutants In addition we will devote some flying hours to a European study EUCAARI that is trying to quantify aerosol properties on a European scale. The new data will be used to characterise aerosol properties typical of the UK and to test how well models describe the evolution of aerosols and their properties. Insights gained will then be used to improve our modelling capability of those processes which control aerosol development. Finally the new data on UK and European aerosol will be compared with existing aircraft, satellite and ground based measurements of other regions to provide a description of how strongly European aerosol effects light in the Earth’s atmosphere compared to aerosol found over other important global source regions such as the Sahara desert and the Amazon basin.
Leeds will use GLOMAP-bin and GLOMAP-mode to investigate the evolution of continental aerosol plumes and the ability of the models to capture changes in aerosol microphysical and radiative properties on various spatial scales. This work will exploit the recent development of a nested version of the CTM.
