Characterization of the Background Natural Aerosol in the West of Ireland
Abstract
Continuous data base measurements of ambient aerosol particle size distributions were made at Mace Head research field station strategically located in the west of Ireland to sense background maritime air from over the Atlantic Ocean and continental air from the European mainland. Selected measurement periods from December 1987 through to June 1988 were used in the work. The measurements show two to three orders of magnitude reduction in aerosol number, mass and surface distribution for the prevailing SW or W wind directions as compared to European continental air sources from the SE or E directions. Two long-normal modes characterized the size distribution data. The first coordinated joint field measurement program of aerosol size measurements at Mace Head and at Great Dun Fell was successfully carried out. The results showed that the aerosol levels are largely preserved - at least at the lower sizes of one particular size range - as the aerosol is transported in the prevailing SW air stream from Mace Head across to Great Dun Fell. Recommendations for further comparative work in this area are advocated. In addition the continuation of this successful initial aerosol data base at Mace Head is recommended.
