Abstract(J)2050年の温室効果ガス削減目標に基づいた排出シナリオを用いて,2050年の日本の大気質に対する東アジアからの越境汚染の影響を大気質シミュレーションにより評価した.その結果,北海道,東北,九州地方で越境汚染の影響が見られた.一方,関東地域への越境汚染の影響は他地域に比べ限定的であった.

Abstract(E)Impacts of transboundary air pollution from East Asia Domain and domestic air pollution in Japan Domain on air quality in Japan in 2050 were investigated by simulations using CMAQ. As a result, it was found that the domestic air pollution had an influence on the concentration of O3 in Japan during whole seasons, while the transboundary air pollution from East Asia had an influence on O3 in Japan in autumn and winter seasons. In the case of PM2.5, both of East Asia and domestic air pollution had an influence on the PM2.5 concentration in east Japan, while East Asia air pollution had larger influence on PM2.5 concentration than domestic air pollution in west Japan.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
