Multiple airshed (MASH) model calculates design values for each of a series of ozone monitoring sites in the U.S. Each monitor is assigned to various airsheds, depending on time of day and the resultant wind direction for each day. Using a list of high values for each airshed, one design value is selected for each airshed and monitor combination. The design value associated with a particular SMSA can be selected from the resulting list of site specific design values which the program generates for each airshed. Input data for MASH are (1) hourly ozone values from monitors, (2) daily resultant wind directions at selected meteorological stations, and (3) a coded set of instructions telling how to allocate hourly ozone values to various airsheds based on wind direction.
