The International Snow Science Workshop (ISSW) exists to facilitate the interdisciplinary exchange of ideas and experiences between snow science researchers and practitioners. The motto of the International Snow Science Workshop is "A Merging of Theory and Practice". ISSW hosts a biennial conference in North America and Europe that brings together researchers and practitioners from all over the world. ISSWs have been geographically rotated between USA-Europe-Canada starting with the first conference in Banff, Alberta in 1976.
