Substances
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
UV Forecast
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
