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
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 35-45 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
