Research:


The climate on Earth strongly depends on the spatial and temporal composition of our atmosphere. Variations in the concentration of airborne particles (aerosol), for example through natural events (forest fires, volcanic eruptions, desert storms) or human activity (fossil fuel burning), result in changes of the heat balance of our planet and affect the global climate. However, the way aerosol influence the heat balance of the Earth by so-called radiative forcing is only poorly understood, because the geographical distribution of aerosol forcing is very inhomogeneous. Databases for global models are incomplete and the acquisition of relevant high quality data require extended monitoring networks. The scope of this project is the expansion of an existing aerosol backscatter LIDAR (light detection and ranging) setup at UCC, to produce quantitative information on vertical aerosol distributions over Southern Ireland for international remote sensing consortia, such as the European EARLINET. For that purpose an existing setup must be redesigned to allow depolarisation ratio measurements in addition to inelastic atmospheric backscatter detection. A LIDAR station in Ireland is particularly important due to its marine environment at the western edge of Europe and its location as an entrance point of air masses into Europe from the northern Atlantic.
