Region V (South-west Pacific) Matt Tully 7th Ozone Research Managers Meeting Geneva 18th – 21st May 2007.
Longstanding Dobson sites • Melbourne: 1957 - 2008 • Brisbane: 1957 - 2008 • Macquarie Island: 1957 - 2008 • Invercargill/Lauder: 1957 - 2008 • Mauna Loa: 1957 - 2008 • Samoa: 1975 - 2008 • Manila: 1978 – 2008 • Singapore: 1978 - 2008
Longstanding ozonesonde sites • Hilo: 1964 - 2008 • Melbourne: 1965 - 2008 • Lauder: 1988 - 2008 • Macquarie Island: 1994 – 2008 • Samoa: 1995 - 2008 • Suva (Fiji): 1997 - 2008 • Sepang (Kuala Lumpur): 1998 – 2008 • Watukosek (Java): 1999 - 2008
Calibration • Regional Dobson Calibration Centre in Melbourne • Regional standard was last intercompared with the world standard in 2006
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 35-45 km since late 1990s
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
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
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
