Description: Seasonal snow is a main element of the global water cycle and climate system. Due to its strong influence on the radiation and energy balance, changes in snow extent tend to amplify climate fluctuations. Terrestrial snow covers up to 50 million km2 and temporal variability. Therefore satellite observations provide the only means for timely and complete observations of the global snow cover. The recently published 2013 IPCC Working Group 1 report identified seasonal snow as significantly decreasing in the recent decades. The importance of accurate data on the global snow cover has been addressed in the WCRP-CliC Workshop and "WCRP Grand Challenges and the Cryosphere in a Changing Climate", held in Tromsö, 16-18 Oct. 2013. The "The role of snow as an active component of the global climate system" has been identified by CliC as a main topic for future research. Also in the WMO Global Cryosphere Watch Workshop in January 2013 the need of intercomparing snow products from various sensors and methods was identified. 

This is the first of two international workshops with the aim to bring together scientists and institutions of seasonal snow pack monitoring for assessing the quality of current satellite-based snow products derived from EO data, and working out guidelines for improvement. To this end, workshop participants are encouraged to submit abstracts for presentations and posters for the workshops.
