Japanese Institute Launches Website for Tracking East Asia Air Pollution

Keywords: Chemicals Ecosystems / Biodiversity University / Research institute 

Japan's National Institute for Environmental Studies announced on February 27, 2009, that it had launched a website to make available online an air pollution map of East Asia, as well as air pollution forecasts and monitoring results, including yellow sand dust events and air pollutant flux from the Asian continent. The site is currently available in Japanese only (see URL below).

Information available on the website includes:
1. Forecasts every three hours for yellow sand events and air pollutants (sulfuric acid aerosol, anthropogenic ultra-fine particles and ozone) on the day and a day after displayed on a concentration distribution map.
2. Forecasts every three hours of yellow sand concentration and distribution at surface and upper air zones (at one, three, and five kilometers in altitude) on the day and day after, and hourly air monitoring data on yellow sand/non-yellow sand events for the past five days, provided by 17 stations in four countries (Japan, China, Korea, and Mongolia).
3. Results of acid rain monitoring at stations of the East Asia Acid Rain Monitoring Network (about 50 stations across 12 countries), which are available as annual mean values from the year 2000 and later.
4. Annual air pollutant emissions (nitrogen oxide, sulfur dioxide, and four other pollutants) in Asia since 1980, as well as forecasts up to 2020.

The website provides a variety of air pollution data -- including yellow sand, acid rain, and air pollutants -- which were previously only available separately under each pollution category. By centralizing the information in one place, it provides users with an easy visual method of tracking changes in air pollution across the East Asia region over time, from both the past and present, plus future forecasts.

The East Asia air pollution map is available at:
