During the 1960’s and early 1970’s observations of increasing acidity of lakes in southern Norway and in the Adirondacks of New York gave an indication that pollutants were being transported great distances from their point of origin. The long transport times were sufficient to allow chemical transformations to occur, adding further complexity. Thus in the early 1970’s the phenomenon of long-range transport of air pollution began to be examined with increasing interest. Studies of transport, transformation and deposition mechanisms have been undertaken and attempts have been made to model these processes. Eliassen (1980) has presented a review of these modelling efforts.
