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 climatechanging conditions

The Oracle-O3 cluster has contributions/interests from

117 researchers from67 research institutions in22 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 feedback6) Data management7) Education, outreach and communication.
