DESCRIPTION:Dr Martin Schneebeli\, SLF Davos Snow & Permafrost group\nAbst
 ract: Snow is a geological material\, and in addition probably the only mo
 nomineralic rock that exists over long times at the surface of Earth at a 
 very high homologous temperature. As a consequence\, the depositional and 
 metamorphic processes form a complex layering\, with properties changing f
 rom hours to years. The measurement of basic structural properties (e.g. d
 ensity\, specific surface area) and physical properties (e.g. thermal cond
 uctivity\, mechanical properties) is a challenging problem\, as these prop
 erties are relevant for a wide range of fields\, as hydrology\, climatolog
 y\, avalanche forecasting and Earth Observation from space. In recent year
 s new techniques and instruments were developed to measure these propertie
 s from the micrometer-scale (e.g. computed tomography) to the m-scale (e.g
 . penetrometry). These techniques enable to quantify the structure of snow
 packs at much higher spatial and temporal resolution than with traditional
  snow profiles\, and bring new possibilities to validate and develop snowp
 ack models.\n\nShort biography: Martin Schneebeli is group leader of snowp
 hysics at WSL and senior scientist. His work is focused on how to measure 
 snow properties quantitatively and at higher spatial resolution\, and from
  the field- to the micro-scale. He is interested in all physical and geolo
 gical processes occurring in the snowpack\, and in different environments.
  In his group a number of instruments are developed\, especially the in-si
 tu micro computed-tomography of snow.
