Since joining CRREL in 1991, Janet Hardy has conducted research in the field of snow hydrology, snowpack physics, and especially the understanding of fluxes, storage, and transformations of energy and water in complex forested environments. Her findings are integrated into existing models to improve representations of these processes in the terrestrial crysophere. Her work has supported major large, scale, international programs such as NASA's Boreal Ecosystem-Atmosphere Study (BOREAS), and NASA’s Cold Land Processes Experiment (CLPX).	Janet Hardy making Infrared measurements of a forest environment.
Areas of Specialization: Snow hydrology Water resources Climate and weather Remote sensing of snow Snow-vegetation interactions Solar radiation, litter and albedo in the forest during snowmelt. Thermal energy transfer in forests Scaling of snow-f orest processes	Infrared image of forest in winter.
Snow cover and its physical properties Snow distribution and measurement of snow properties Permeability, capillarity, snow pack evolution, and meltwater routing Snow fraction mapping for improving operational hydrologic forecasts Current Projects: The effects of tree elements on thermal signatures and the scaling of these effects. Influence of sub-grid variability on snow deposition and ablation in North America mountain environments: Implications for upscaling to meso-scale representations. Application of the SeaWinds scatterometer for monitoring seasonal freeze/thaw dynamics for improved assessment of circumpolar boreas/arctic terrestrial ecosystem and hydrologic processes. Snow depth, soil frost and nutrient loss in a north temperate forest. Notable Contributions or Highlights from Past Projects: Linked CRREL’s snow process model SNTHERM, with a canopy model to accurately predict snow ablation beneath various forests. Improved fundamental understanding of, and ability to model, radiative processes in forests as well as the scaling of those processes. Conducted the first detailed study of forest debris accumulation on the snow surface, its incorporation into a snow process model, and its impact on the spectral albedo. Led the organization of a major international conference on snow hydrology and the editing of peer-reviewed publications.
