  1. Ozone layer and UV radiation in a changing climate evaluated during IPY(ORACLE-O3)Project within the IPY cluster Clouds, aerosols and atmospheric chemistry Peter von der Gathen AWI Niels Larsen DMI

  2. Background Nearly 1000 Expressions of Intents (EoI) were submitted to the IPY Joint Committee early 2005 Recommendations for clustering of EoI’s Within the cluster ”Clouds, aerosols, and atmospheric chemistry” 15 EoI’s have been identified, related to research on the stratosphere and UV under climate changing conditions The Oracle-O3 cluster has contributions/interests from 117 researchers from 67 research institutions in 22 countries Science programme, data management and outreach 1) Ozone loss (detection and impact on UV radiation, 2) PSC (polar stratospheric clouds) and cirrus, 3) Atmospheric chemistry, 4) UV radiation, 5) Ozone and climate change and feedback 6) Data management 7) Education, outreach and communication.

  3. Funding and coordination • Draft Preparation Form for Proposed IPY Activity • CO-PI’s: Peter von der Gathen, AWI and Niels Larsen, DMI • National IPY Committees • National IPY research programmes • International coordination - (COST action ?) • Science programme, data management and outreach • 1) Ozone loss (detection and impact on UV radiation • 2) PSC (polar stratospheric clouds) and cirrus • 3) Atmospheric chemistry • 4) UV radiation • Ozone and climate change and feedback • Data management • 7) Education, outreach and communication.

  4. Quantification of polar ozone losses in both hemispheres Match technique Simultaneous satellite measurements of ozone and reactive chlorine and bromine Envisat ACE Aura Odin

  5. Investigations of Polar Stratospheric Clouds Solid particle formation Denitrification Trace gas measurements Calipso lidar PSC detection SAF LearJet H2O M55-Geophysica Particle and trace gas measurements DLR-Falcon O3-aerosol lidar Stratospheric balloons Particle measurenets H2O BAe-146 Tandem flights with M55 GB lidars

  6. Ground-based measurements Rio Gallegos Ushuaia Marambio Belgrano Instruments operating in the IR, UV/Vis and microwave, Lidars, O3-sondes Seasonal and long-term variability Ozone, water vapour, numerous key ozone-related trace gases in the stratosphere Tropospheric pollutants, greenhouse gases, and biomass burning UV-, visible, and infrared radiation and ground/sea/ice albedo, AOD

  7. Modelling Chemistry-transport models Chemistry-climate models Integration of field data and process studies in a modelling framework Chemical assimilation Changes in SH vortex dynamics Recovery of the ozone layer

  8. UV-effect studies: Epidemiological study of personal UV exposure. Deepen our understanding of the role of the variability of light and UV radiation on primary production and human population. Variability and trends of the relevant biologically effective doses in polar areas, and their sensitivity to changes in snow and cloud cover. Explain differences in phytoplankton biomass, melatonin and vitamin D levels as a function of the variability of relevant biologically weighted doses. Establish foundations for future data products on UV and visible radiation.

  9. Collaboration • National IPY research programmes • NERC IPY special fund • NERC Antarctic Funding Initiative • Italian Programme for Antarctic Research (PNRA) • German IPY programme under way • Link to EU- research • European Commission funded Integrated Project • Stratosphere-Climate Links With Emphasis On The UTLS (SCOUT-O3) • Management structure • Data management data protocol, data base • Conferences
