QA4EO SnowPEx:
Satellite Snow Product Intercomparison and Evaluation Exercise

Minimize Workshop

Seasonal snow is a main element of the global water cycle and climate system. Due to the 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 of the Northern Hemisphere in winter, and is characterized by high spatial 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 during recent decades. The importance of producing better global scale snow cover data sets has been addressed in the WCRP-CliC Workshop on "WCRP Grand Challenges of the Cryosphere in a Changing Climate", held in Tromsö, 16-18 Oct. 2013. 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 working in seasonal snow pack monitoring in order to assess the quality of current satellite-based snow products derived from EO data and work out guidelines for improvement. Scientists are encouraged to submit abstracts for presentations and posters for the workshops.
