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

Slide2: 

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.

Slide8: 

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

Slide9: 

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.
