COST-727 - Atmospheric Icing on Structures, Measurements and data collection on icing: State of the Art

Abstract

COST Action 727 "Measuring and forecasting atmospheric icing on structures" was estab- lished in April 2004 and comprises 12 signatory countries: Austria, Bulgaria, the Czech Re- public, Finland, Germany, Hungary, Norway, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. Following the "Memorandum of Understanding" (MoU), three working groups were established, WG1 "Icing modelling", WG2 "Measurements and data collection on icing" and WG3 "Mapping and forecasting of atmospheric icing". The present report covers the work of WG2 during Phase 1 of the Action. The main scope of this phase was to create an inventory of earlier and current activities on icing measurements, data resources and instrument testing. The emphasis is on activities within the signatory coun- tries, however some additional information from other countries like Russia and Canada is included as well. It is important to notice that COST does not support project activities. Therefore all contribu- tions concerning individual countries are provided according to available time and engage- ments of the participants. Hence the structure and details of each contribution will vary, and the reader will not necessarily find the same information for all countries. A lot of references are given, however, and the reader will find links to institutions where further information can be retrieved. It is the intention of Phase 2 to structure and update information from existing test sites and open data sources in a more systematic way than was possible in this report. Phase 2 will also include instrument comparisons from test sites, and also elaborate recommendations for WMO observations and permanent data bases for icing in Europe. COST Action 727 acknowledges Dr Wiel M. F. Wauben, the Royal Netherlands Meteorologi- cal Institute (KNMI) for reviewing this report and MeteoSwiss for their generous offer to print the rep
