Component technologies for estimating air quality in case of environmental assessment were studied. We proposed a new method to analyze wind features in a wide area including three or more monitoring stations for meteorological observation. We also proposed how to reflect the features of topography to estimate three dimensional wind vectors from two dimensional wind vectors. We selected air quality monitoring stations in Hiroshima city, and set three dimensional boxes in the study area. One year wind and meteorological stability patterns of four stations were analyzed and our result indicated that we could make our wind data more compact and easier to handle after filtering by our pattern analyzing method. We then estimated two dimensional wind vectors of every three dimensional box including air quality monitoring stations and verified applicability with real counted data.
