Cold Regions Hydrology and Hydrometeorology
This session welcomes scientific submissions that discuss recent and projected changes to cold regions hydrology and land surface processes and developments in predictive capability of the hydrology and hydrometeorology of regions that are affected by snowfall, snow cover, frozen ground, river/lake ice or glaciers. Of particular interest is work outlining field and/or remote sensing studies of hydrological and hydrometeorological processes, the use of models in diagnosis and prediction of hydroclimatic change, the representation of cold region processes in land surface schemes, and regional climate model applications. As there is abundant evidence that the extremes of precipitation and streamflow will intensify with global change, this session also encourages submissions that investigate the characteristics and behaviours of these particular events in the context of cold regions hydrology and hydrometeorology and their predictability at various scales.

Land surface modelling for GCMs and ESMs
The importance of land surface processes and feedbacks in the global climate system has long been recognized, and decades of research have gone into the development of land surface schemes for global climate models (GCMs) and earth system models (ESMs). The development of such land surface schemes involves particular challenges, in that they must include physical processes operating at sub-diurnal time scales and at local spatial scales, but must also be capable of being applied at century-long time scales and global spatial scales. Thus, for example, although testing of the models with field data is of key importance in validating the physical realism of their parameterizations, this must also be complemented with regional-scale validation, usually using remote sensing observations. Ongoing research must also address the perennial problem of representing sub-grid scale heterogeneity in vegetation, soils, surface water and ground or surface ice, as well as the new frontiers of adding biogeochemical cycles, vegetation dynamics and the effects of surface disturbances. In Canada, 2016 will mark thirty years of development work on CLASS, the Canadian Land Surface Scheme, and nearly fifteen years of work on CTEM, the Canadian Terrestrial Ecosystem Model. This model development work has involved dozens of researchers in Canadian government and university centres, and numerous collaborations with researchers internationally. This session invites presentations on current work in CLASS and CTEM development, as well as work on the development of other land surface schemes designed for climate and weather models.
