EARSeL LISSIG 2014

Snow Workshop 2012

EARSeL LISSIG 2011

Innsbruck 2010

The 1st ESA DUE GlobSnow User Workshop was held in Innsbruck 12 - 13 January 2010


Overview

The User WorkShop 1 of the ESA DUE GlobSnow project was held at Hofburg, Innsbruck, Austria, during 12-13 January 2010. The purpose of the meeting was to present the work carried out during the first phase of the project, including: the algorithm evaluation results for Snow Extent (SE) and Snow Water Equivalent (SWE) products, the selected GlobSnow algorithms and the prototype datasets. A key objective was to openly discuss the results obtained and determine the direction of the project in the future with the user community. In addition to the presentations given by the GlobSnow consortium, the User community gave presentations on several different topics concerning the GlobSnow and satellite-based snow and cryosphere monitoring efforts in general.

The minutes of the meeting give an overview on the presentations and the discussion that took place.
