  1. Call for Participant Applications
    Workshop on Greenland Ice Sheet Stability
    National Science Foundation
    11-12 September 2017
    Buffalo, New York

How the Greenland Ice Sheet responds to climate change is important to
society for a number of reasons, one of which is sea level rise.
Understanding ice sheet stability is central to this effort. However,
current data or models do not allow for a definitive consensus view of
ice sheet variability during the past.

Application deadline: 15 June 2017.

Addressing the issue of Greenland Ice Sheet stability requires input
from a range of disciplines that focus on four major and integrated
approaches that, collectively, have the highest potential for going
forward and include ice and bedrock coring, stratigraphy and chronology,
ice sheet modeling, and ice sheet processes.

The goals of this workshop include:

  • Utilize the workshop's community of experts to bring together
    different datasets and approaches to see whether consensus can be
    reached on the current state of knowledge of Greenland Ice Sheet history
    and sensitivity to climate forcing, and
  • Develop key research priorities that will help guide future efforts on
    the problem of Greenland Ice Sheet stability.

Attendance for the workshop is limited. Partial travel support may be
available for early career researchers.

  1. Call for Registration
    Multi-scale Modeling of Sea Ice Characteristics and Behavior
    Isaac Newton Institute for Mathematical Sciences
    11-15 September 2017
    Cambridge, United Kingdom

This workshop will address sea ice processes across a wide range of
lengths and time scales, with an emphasis on understanding emergent and
scale-invariant phenomena. Mathematical methods that account for the
smaller scale processes and enable computation and analysis of these
processes' effect on larger scales relevant for coarse-grained climate
models will be a focus of the workshop and linkage of scales is a
central theme of this workshop.

Registration deadline: Sunday, 11 June 2017.

Workshop Theme:

Realistic models of Earth's climate system are essential to making
projections about what we may experience as our climate changes. Polar
sea ice forms a critical system component which must be accurately
accounted for in global climate models. It forms the thin boundary layer
coupling the polar oceans and atmosphere and has seen rather dramatic
changes over the past two or three decades. An important feature of sea
ice is that it displays rich structure and behavior on scales ranging
over 10 orders of magnitude, length scales from microns to hundreds of
kilometers, and time scales from milliseconds to decades. This broad
range of scales for sea ice structure and properties is relevant to
biological, chemical, industrial, weather, and climate-related
processes. It also leads to sea ice structure at certain scales being
similar to other materials such as porous human bone and polycrystalline
metals, which can be used to bring new techniques to studying sea ice.

The complex behavior of sea ice over such a large range of scales
presents a fundamental challenge to modeling these systems. For example,
many key processes, whose relevant length scales may be centimeters or
meters to kilometers, impact climate and must be incorporated into
largescale numerical climate models with grid sizes often on the order
of tens of kilometers. Moreover, some sea ice properties exhibit scale
invariance or predictable scale dependence while others appear to be
wholly emergent, a consequence of interacting processes within and
applied to the ice cover.

Potential workshop topics include:

  • Large-scale numerical models of the evolution of polar sea ice;
  • Sea ice simulations including variability, predictability, and climate
    projections;
  • Sea ice microphysics, fluid transport, convection, and the porous
    brine microstructure;
  • Melt ponds on Arctic sea ice;
  • Ice thickness distribution, melting, freezing, mechanical
    redistribution, ridging, and rafting;
  • Waves in the marginal ice zone;
  • Scaling in sea ice fracture and dynamics, sea ice rheology;
  • Momentum balance including form drag, interactions with currents,
    tides and winds;
  • Sea ice thermodynamics and exchange processes;
  • Low order models of polar climate;
  • Tipping point phenomena; and
  • Stochastic processes in sea ice modeling.

    2nd MAR Regional Atmosphere Model Workshop
    13-15 September 2017
    Grenoble, France

Organizers announce the 2nd Regional Atmosphere Model (MAR) workshop.
The workshop will convene 13-15 September 2017 in Grenoble, France.

A call for abstracts will be announced on the MAR website:
http://mar.cnrs.fr/index.php?option_smdi=actualite&id=12.

The workshop will consist of one day of courses about model use and two
days of communications and discussions about model results and
development. The new MAR website will also be presented during the
workshop.

MAR is an atmosphere model designed for meteorological and climatic
research and is used for a wide range of applications, from
kilometer-scale process studies to continental-scale multi-decadal
simulations. This model is known for its representation of physical
processes in polar regions and is one of the few models able to simulate
realistic surface mass balance, air-snow interactions, and atmospheric
circulation over ice sheets, including katabatic winds. MAR has led to
significant advances in the understanding of the surface mass balance of
mid-latitude and tropical glaciers and has provided climate simulations
over Europe and Africa.
