Abstract

One model is the three-dimensional Urban Air-Shed Model which has been adapted to calculate O₃ concentrations in the Tokyo area. However, accurate calculations require proper specification of boundary conditions and of emission characteristics. This study is directed towards determining the sensitivity of the O₃ prediction procedure to variation in boundary values; and to variation in the source emission of organics and nitrogen oxides. The effects of using different boundary assumptions are compared. All calculated results are also compared, using actual meteorology, with a large data set of ambient concentrations (NO, NO₂, O₃, and 17 Hydrocarbons) collected both aloft and at ground-level in the Tokyo region in the summer of 1981. There is a short general discussion at the end of the article. -from Authors
