Dear colleagues,
we would like to draw your attention to the symposium on observation and modelling of interactions between the atmospheric boundary layer and snow/ice surfaces at the IUGG General Assembly in Montreal, Canada (9-13 July, 2019). A full symposium description is given below.
This is joint symposium between the cryosphere, atmosphere and hydrology communities.
The deadline for submission is 18 February 2019 and the portal for abstract submission is: http://iugg2019montreal.com/abstract-submission.html
Best regards,
Vincent Vionnet, Rebecca Mott, Ethan Gutmann, Ruzica Dadic, Tobias Jonas and John Pomeroy

JC08 Coupling Processes between the Atmospheric Boundary-Layer and Snow/Ice Surfaces: Observations and Modelling
Convener: Vincent Vionnet (Canada)
Co-Conveners: Ruzica Dadic (New Zealand), John Pomeroy (Canada), Tobias Jonas (Switzerland), Rebecca Mott (Switzerland), Ethan Gutmann (USA)
The symposium addresses fundamental exchange mechanisms of mass and energy between the cryosphere, vegetation and the atmospheric boundary layer in snow-covered regions. The interaction between the near-surface atmosphere and the cryosphere can lead to significant spatial and temporal variations of momentum, mass- and energy exchange as well as complex atmospheric flow patterns that are modulated by complexities in topography and vegetation cover. These processes strongly affect the evolution of seasonal snow cover, permafrost, sea ice, vegetation and glaciers and drive snow and ice hydrology.
We invite contributions on, but not limited to, the following topics:
- treatment of turbulent fluxes over snow in models and measurements
- advection of energy to snow-covers and glaciers and impact on snow and ice melt
- orographically-induced precipitation and preferential deposition of snowfall
- wind-induced snow transport and associated sublimation
- impact of vegetation on snow/atmosphere interactions
