Improvement of Ash Cloud Information by Tokyo VAAC

The Tokyo Volcanic Ash Advisory Center (VAAC), operated by the Japan Meteorological Agency (JMA), monitors satellite imagery and obtains foreign and domestic reports on volcanic activities. The Tokyo VAAC issues volcanic ash advisories (VAAs) if volcanic ash is likely to affect any air routes in Asia or the Western Pacific area. These VAAs contain information on the present status and forecasts of future dispersion of the volcanic ash clouds. The information is in the graphical and text format used by civil aviation authorities and by Meteorological Watch Offices. The paper discusses the automatic issuance of VAAs for volcanoes in Japan, improvement of the forecast precision of volcanic ash cloud dispersion, and the Tokyo VAAC website that is now open to the public.
