COST-727 Action: icing on structures

The COST-727 Action "Measuring and forecasting atmospheric icing on structures" was established in April 2004. The following general goal was then defined: to develop the understanding of icing (especially in-cloud icing) and freezing rain events in the atmospheric boundary layer and their distribution over Europe as well as to improve the potential to observe, monitor and forecast them. Phase 1 of the action was dedicated to gathering available information for a comprehensive state-of-the-art report representing what the participants consider as a summary of today's available knowledge. The second Phase of the Action is dedicated to in-situ measurements of atmospheric icing with selected reference icing sensors at 6 stations operated in Europe and to the modeling of selected icing events with a new adaptation of the WRF model developed by Norway. The following deliverables are expected:
