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

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

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

7. “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 7 Experimental VA Product

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

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

10. 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 10 Future Improvement in Observation Field

11. 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 11 Further Efforts…
