Atmospheric Particles and their Interactions with Natural Surfaces

The purpose of this short review will be to focus on those aspects of aerosol exchange which are of importance to the BIATEX community in order to aid in the assessment of acidic or alkaline deposition, from dry and wet aerosol (in the form of cloud or fog droplets) over Europe with an eye to the larger scale processes in which aerosols play a critical role. One of the important goals of the Biatex program, emphasised by its co-ordinator, has been the necessity to deliver information about these processes which are “useful” to wider interests, in particular the modelling community. In light of the co-ordinators plea for “immediately useful information” a detailed summary of parameterisations which have been forthcoming in BIATEX and related programmes for both dry and wet aerosol deposition are listed in the Appendix.
