Climatological Variability in the Evaluation of Cost Effectiveness of Emission Control Strategies to Reduce Acid Deposition
One of the major problems with designing control strategies for acidic deposition is that potential future deposition patterns must be simulated using past meteorological conditions. We can estimate the future emission patterns that would result from the implementation of a given control strategy, but efforts to predict what effect these emission patterns would have on future deposition levels are hampered by uncertainty about future transport and deposition climatology. This problem has been set aside in most previous work by using a single past year of meteorological data as a surrogate for all future years. This meant that we could estimate the amount of deposition that would occur at a particular location as a result of a particular control strategy, and indeed we could design an emission reduction strategy to achieve a desired amount of deposition, but we could not predict how that level of deposition might fluctuate from year to year as a result of natural climatological variation. With the recent processing of a six-year record of meteorological data, however, these questions can now be investigated.
