From 02-05 April 2013 the first international „Snow Grain Size Workshop – Measurements and Applications“ was held in Grenoble, France. The workshop was organized by G. Picard (LGGE), H. Löwe (WSL/SLF) and S. Morin (CNRM-GAME/CEN), with local support from LGGE and CNRM-GAME/CEN. The 50 participants came from France, Switzerland, Japan, Finland, USA, United Kingdom, Netherlands, White Russia, Canada, Luxembourg, Norway, Germany and Turkey.
The goal of the workshop was to gather snow grain size specialists and initiate discussions and activities about i) the accuracy and comparability of existing methods, which provide objective grain size estimates in the field ii) the scope and limitations of commonly used grain size variables. Measurement devices brought by the participants were demonstrated by the experts during the field excursion to La Grave. For details of the program cf. (http://snowgrain2013.sciencesconf.org/). The workshop was sponsored by Labex OSUG@2020, Microdice (ESF), IACS, Meteo-France and LGGE.
