Measurements of aerosol mass have now begun to be routinely measured at the Mace Head site. The next phase will include the measurement of particle size distribution as measured from segregated particulate samples from impactors see Section 3 and through the use of Knollenberg light scattering aerosol spectrometer probe. It is planned to have an integrated and coordinated aerosol measurement programme with UMIST, Manchester in November. This should permit the first time of study of the evolution of the natural aerosol as it is transported across western Ireland over the Irish and British land masses on its progression towards mainland Europe. The described work provides the first characterization and monitoring of the physical properties of the cleanest background aerosol at the remote site at Mace Head, in western Ireland which possesses the distinctive advantage of being strategically located at probably the cleanest background field research in the most westerly geographical locale in western Europe. Further anticipated results from the work should lead to the establishment of an unique data base of natural background aerosol for this strategic remote site at Mace Head. This data base should serve as an important reference baseline with which to compare influxes of aerosol other than background aerosol, as measured directly or remotely sensed with point type detectors or optically remote sensors.
