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
