14 Region V Monitoring of Ozone Depleting Substances

15 Longstanding Dobson sites Melbourne: Brisbane: Macquarie Island: Invercargill/Lauder: Mauna Loa: Samoa: Manila: 1978 – 2008 Singapore:

16 Longstanding ozonesonde sites Hilo: Melbourne: Lauder: Macquarie Island: 1994 – 2008 Samoa: Suva (Fiji): Sepang (Kuala Lumpur): 1998 – 2008 Watukosek (Java):

17 Calibration Regional Dobson Calibration Centre in Melbourne Regional standard was last intercompared with the world standard in 2006

18 NIWA Results and Analysis NIWA combined total column database NIWA combined vertical trace gas and aerosol profile database Microwave radiometer and Lidar show an increase in ozone over Lauder between km since late 1990s

19 UV Forecast

20 Australian Ozone Science Group Australian Antarctic Division, ARPANSA, Bureau of Meteorology, CSIRO, University of Melbourne (organised by Department of Environment) Information sharing and co-ordination of activities Advice to government, media and general public

21 Future Plans NIWA and New Zealand Cancer Society have just begun 3 year study into UV exposure and Vitamin D Bureau of Meteorology plans to begin an ozonesonde program in Darwin Bureau of Meteorology developing low- cost UV spectroradiometers for Solar & Terrestial Radiation network sites

22 Challenges Maintaining observing networks (financial and human resources – expertise) International isolation Evaluation of historical data Climate change and ozone depletion links Models unable to reproduce response of Southern Hemisphere ozone to Mt Pinatubo
