Atmospheric icing of structures is a serious challenge affecting a wide variety of man-made structures and activities, such as land, marine and air transportation, electric power networks, wind turbines, telecommunication networks, and work environment in affected areas.

The primary mission of IWAIS, the International Workshop on Atmospheric Icing of Structures, is to bring together leading researchers and industry representatives to facilitate exchange and interaction in view of finding practical and economical solutions to the disruptive effects of atmospheric icing. The first IWAIS conference was held way back in 1982 in Hanover, USA. A list, information and proceedings of some previous conferences, can be found at previous conferences. The diversity of the locations of the past IWAIS workshops illustrates the extent of impacts of atmospheric icing.

The eighteenth conference, IWAIS 2019, will be held in Reykjavík, for the second time in Iceland. Researchers, students and industry delegates from many countries around the world, mainly from North America, Europe and Asia, are expected to attend. The workshop will cover a wide range of topics, including icing measurement and modeling, icing of power network equipment such as conductors and insulators, wind turbines, techniques to reduce ice adhesion and accretion, health and safety issues, icing standards, and other topics related to atmospheric icing of structures.
