WORKSHOP - Workshop on Ion-Aerosol-Cloud Interactions (1/3)

by (CERN)

Wednesday 18 Apr 2001, 09:00 → 10:00 Europe/Zurich

503/1-001 - Council Chamber (CERN)

Aim: The European Geophysical Society, the European Physical Society and the European Science Foundation are co-sponsoring an inter-disciplinary workshop to review the present knowledge of ion-aerosol-cloud interactions and their possible role in solar-climate variability, and to discuss the experimental requirements, design and experimental programme of the proposed Atmospheric Research Facility using a particle beam at CERN.
