Advances in large-scale land surface, hydrological and climate modelling over snow and ice-covered mountainous terrainPICO session
To describe atmospheric, land surface and snow cover processes over mountainous regions seasonally covered by snow is challenging. While many communities work on a wide range of topics, including snow, avalanches, glaciers, snow hydrology, weather forecasting or climate modelling, often similar issues have to be addressed:
(1) Obtaining reliable input or validation data, which involves techniques such as statistical or dynamical downscaling, post-processing of coarse-scale meteorological data, or the interpolation and assimilation of in-situ and remotely sensed observations;
(2) Representing unresolved small-scale processes in coarse-scale model grid cells, e.g. by using subgrid parameterizations;
(3) Evaluating model performance and improvements in data sparse mountain areas.
This session aims at bringing together researchers from various fields to explore the common issues, share specific expertise across disciplines, and discuss possible solutions to current problems.
