319 Numerical simulation of photochemical air pollution in Osaka area : Influence of increased surface albedo and emission reduction on oxidant concentration
Details
A series of numerical simulation was executed to investigate the photochemical Ox pollution in Osaka area. When the surface albedo of the urban area is increased to mitigate the mid-summer thermal environment, temperature decrease weaken the sea breeze, and it may cause the increase of the Ox concentration level. Sensitivity test about NOx and NMVOC reduction on the daily maximum Ox concentration shows that the most of the city area is NMVOC-limited. In some areas, reduction of solely NMVOC is more effective than both reduction of NOx and NMVOC.
