1. Services & Products of Tokyo VAAC Jun Ryuzaki 30 October, 2012 FPAW in Orlando Tokyo Volcanic Ash Advisory CenterJapan Meteorological Agency

2. Area of Responsibility Tokyo VAAC • Tokyo VAAC started its operation in 1997 • Close coordination with Anchorage & Washington VAAC.

3. “Busiest” VAAC in the World? Bezymianny ( 2) 60N Kliuchevskoi ( 11 ) Sheveluch ( 179 ) ▲ ▲ ▲ ▲ Kizimen ( 223 ) Karymsky ( 52 ) 50N 40N Asosan( 56 ) Kirishimayama( 184 ) ▲　：　Volcanoes location Black letters : Volcano Name Blue Number : Number of Issued VAAs ▲ Sakurajima ( 1000) ▲ ▲ 30N ▲ Suwanosejima ( 37) + Other transfer VAAs ▲ Grimsvotn( 5 ) ▲ Pagan ( 6 ) 20N Bulusan( 30 ) ▲ • 1785 VAAs were issued for 12 volcanoes only in 2011. 10N 110E 120E 100E 130E 140E 150E 160E 170E

4. Operational Efforts of JMA • Dedicated VA forecaster (since 2011) • Close collaboration with JMA volcanologists • Semi-Automated operating system with GUI Tokyo VAAC operations room in Tokyo, JMA HQs

5. Information Flow of VAA Pilot Reports Volcano Information Satellite Observations NWP GPV • Monitoring & Analysis of VA Cloud • Forecasting of Volcanic Ash • Issue of Volcanic Ash Advisory (VAA) Tokyo VAAC/JMA • ICAO ANNEX3 VA products • Text VAA (FVFE01) / Graphical VAA (VAG) • Additional VA products (Domestic) • Graphical products (VAGI, VAGFN, VAGFNR) Volcanic Activity Reports Foreign VAACs Meteorological Watch Officesin area of responsibility Aviation Weather Service Centers in Japan Civil Aviation Authorities andOther Related Organizations

6. Additional VA Products (Example) • Volcanic Ash Graphic Information (VAGI) VA area identified with Satellite imagery Major Air-Route Top Height (FL) Movement/Speed 6

7. Experimental VA Product • “Volcanic Ash Dispersion Chart for Mt. Sakurasima & Mr. Kirishimayama” • Assuming Eruption of 2 very active Volcanoes • Forecast up to 3 hours later,3 hourly updated • Ash Dispersion and Deposition from the two volcanoes • Help Air Traffic Controllers, Airline Dispatchers, and Aircraft pilots; • Immediate response to mitigate risk of VA encounter • Consider possibility of VA fall over airports nearby • Now under Evaluation by Users • Started since 29 July,2010

8. Experimental VA Product Miyazaki Airport Kagoshima Airport FL100 to FL200 Surface to FL200 FT=3 FT=1 FT=2

9. Further Development Estimation of ash dispersion/deposition for assumed eruption of Mt. Sakurasima & Mt. Kirishimayama • Deposition Area will be directly forecasted • by JMA’s future VA deposition prediction model Deposition Area(Hatced)

10. Future Improvement in Observation Field • New MET Satellite will be launched in 2015 • Multi-Channel Sensors equipped • Rapid Scan (every 10 minutes) • High Resolution (1km) • Ground Radar Observation for VA • VA Height and Vertical Profile can be obtained

11. Further Efforts… • Enhance collaboration with Anchorage VAAC • Use of collaboration tool (being discussed) • Establish ment of back-up procedure • With Darwin VAAC (Australia) • Routine exercise also will start soon • Improve harmonization between VAACs • VAAC Best Practice Seminar • Enhance contribution to scientific groups • WMO VA Scientific Advisory Group (VASAG), the other related seminar/workshops
