Why this working group?
Users of “snow grain size”
I Microwave remote sensing (CoreH2O)
I Optical remote sensing
I Climate modeling (snow albedo)
I Energy balance over snow
I Snowpack modeling in general
Rhetorical question:
I Do you really want to validate the problems above with a“grain size” measured by eye with a loupe?
WG goal:
I Shape a community-voice for “grain size” issues
Snow Grain Size Workshop, Grenoble 2013
Theory....
… and practice.
Organizers: G. Picard, S. Morin, H. Lowe, L. Arnaud, M. Dumont
Outcome: Strong community agreement
I Necessity for an intercomparison workshop (Davos)
I Necessity for a workshop tailored to microwave remote sensingapplications (Reading)
Intercomparison of Snow Grain Size MeasurementsWorkshop, Davos 2014
Organizers: M. Schneebeli, T. Aoki, L. Arnaud, F. Domine, S. Morin,
G. Picard, M. Sturm, M. Proksch, M. Jaggi, M. Matzl
Outcome: Dissemniation in TC special issue (04.2015–12.2016):Intercomparison of methods to characterize snow microstructure
MicroSnow Workshop on Microstructure in SnowMicrowave Radiative Transfer, Reading 2014
Organizers: M. Sandells, N. Rutter, M. Horhold, I. Davenport, S. Linow,
W. MaslankaOutcome: Broad agreement
I Need for a campaign: microstructure and microwaves
I Keep the momentum: MicroSnow II workshop
MicroSnow: Working Group, Workshops
Main achievement:
I Formation of a strong “grain size community”
Main theme:
I Good discussions, less competition, more collaboration
