Abstract

This paper discusses the use of a long-term Lagrangian receptor-oriented trajectory model for assessing acidic deposition to the United Kingdom at high spatial resolution. Previously, a coarse resolution of 20 km was used. Impact assessments using the critical loads approach now require higher-resolutions of modelled data for future scenarios. In this paper, first results from a higher resolution of 5 km using a revised parameterization of orographic enhancement of the seeder-feeder effect. It was found that country budgets for the two different model resolutions were in good agreement and compared well with observations, except in the far north of Scotland where the straight-line trajectory approach is less valid.
