IACS scientific assemblies, symposia and workshops

One of the primary goals of IACS is to promote the Cryospheric Sciences through scientific exchange. Thus, much effort goes into establishing scientific meetings. IACS participates in scientific assemblies of the sister organizations IAG, IAGA, IAHS, IAMAS, IAPSO, IASPEI and IAVCEI and in the IUGG general assemblies. The IUGG assemblies occur every four years (next will be in Melbourne, Australia in 2011). The scientific assemblies also occur every fourth year but shifted four years relative to the IUGG assemblies. IACS also promotes and sponsors workshops and symposia organized by its Divisions, Working Groups as well as by other organizations.

J!: Modelling Forest Snow Processes.

Intercepted snow on forest canopies has a large exposed area for exchanges of mass and energy with the atmosphere. Snow on the ground beneath a forest canopy, compared with snow in open areas, is sheltered from wind and solar radiation, but receives increased longwave radiation from the canopy. Forests thus influence the timing and quantity of runoff from snowmelt, and changes in forest cover, whether managed or in response to changing climates, modify this influence. Contributions are invited on how snow processes can be represented in large-scale atmospheric and hydrological models, and on how such process models perform in composition with observations

J2: Glacier mass balance and its coupling to regional to hemispheric circulation.

Glacier mass balance measurements constitute an important contribution to our understanding of climate change. From a climatological perspective, glacier mass balance constitutes a point measurement in relation to large-scale atmospheric climate factors. However, local factors can be important. For example, snow accumulation is governed by a combination of direct snowfall and wind transport. To extract the mesoscale circulation pattern from the mass balance data, local and mesoscale influences need to be distinguished. The aim of this workshop is to examine how mass balance data can be used to infer mesoscale circulation patterns. If successful, we can use GCM’s to predict future glacier changes and past glacier extents. This workshop follows on two previous ICSI workshops on glacier mass balance (Melbourne, 1997; Tarfala, 1998).

J3: Mountain Snow and Ice Cover (ICSI, IAMAS)

In many parts of the world mountain snow and ice covers represent (up to now) continuously renewed water reservoirs, but also present periodical threats to human safety. The importance of these water reservoirs increases even more in a warming climate, mainly due to large-scale interactions with air flow and sea water circulations. This symposium is intended to promote the exchange of knowledge between snow/ice cover modellers and researchers dealing with climate modelling. Achieving proper representations of the boundary conditions between snow/ice and atmosphere will be a major topic.
