Wet deposition to an upland area of England in 1988 and 1999; measurements and modelling

摘要

Fine spatial-scale measurements of acidic deposition have been made over to time frames: 1987/1988 and 1999/2000. Over this period, dramatic reductions in precursor emissions have occurred. The two sets of data are compared in order to quantify deposition reductions. Orographic enhancement of wet deposition from the seeder-feeder mechanism is important in the UK at high-elevation sites such as these and the measurements were corrected for this process Using a standard methodology.
