摘要

Cloud treatment in the URM-1ATM model appears reasonable. Accuracy problems were most notable for one episode. The need to simulate heterogeneous chemistry requires a criterion for determining cloud presence that does not conform to meteorological convention. Despite this the model representation of cloud presence and cloud amount matched observations well. The role of heterogeneous chemistry varied greatly according to the meteorological circumstances. Heterogeneous oxidation produced less than a quarter of the sulfate during a rainy summer period, but two-thirds of the sulfate during an extremely dry summer period. Regions modeled to have low sulfate levels were less likely to have active heterogeneous chemistry than areas computed to have high sulfate. Overall, heterogeneous sulfate formation accounted for about half of the total sulfate produced.
