Estimation of sulphate concentration in high elevation fog in Northeastern North America
Alternate approaches for estimating deposition of acidifying compounds by fog are needed. This paper presents empirical models for estimating concentration of SO 4 2− in fog at high elevation locations in eastern North America. They are based upon meteorological predictors, pollutant emissions data...

2− in fog at high elevation locations in eastern North America. They are based upon meteorological predictors, pollutant emissions data and ambient ozone measurements and were developed using fog measurements from the chemistry of high elevation fog (CHEF) and the mountain cloud chemistry program (MCCP). Optimum models have a relative error (RE) of 0.37, indicating that the variance in the fog SO

2− observations could be reduced by 63%. In addition to meteorological observations from nearby airports, the best models also utilized information on air mass history determined from back-trajectories. Ozone, measured at the fog collection site, was also found to be a potentially useful predictor of SO
