Summary
Abstract: Main thrusts in CRYSYS snow-related research are: (1) the development and
validation of microwave algorithms for snow cover properties (extent, water
equivalent, wet/dry state) in varying landscapes, and the synergism between
active and passive microwave data for snow studies; and (2) reconstruction of
historical snow cover from conventional and remotely sensed data to document
and better understand long-term variability in snow cover.1. Develop, validate
and refine empirical and theoretical algorithms for snow cover properties
(extent, water equivalent, wet/dry state) in varying landscapes using passive
and active microwave data.

2. Integrate multi-sensor data to produce snow cover maps of selected
regions of Canada.

3. Provide snow state variables for input to distributed hydrologic
and coupled hydrologic-atmospheric models to monitor the snowpack, estimate
runoff, and feedback to the atmosphere.

4. Assess the compatibility and applicability of data and products
from current operational passive microwave sensors (SSM/I) with EOS data (e.g.
AMSR, MODIS).

5. Document and understand variability in snow cover and snow
cover/climate interactions over a range of spatial and temporal scales from
merging of in situ and remotely-sensed data.

6. Contribute to the validation of snow cover and
snow/climate/hydrological interactions in models (e.g. global/regional climate
and atmospheric models).

7. Rescue significant Canadian snow cover data sets e.g. daily snow
depth and snow course observations.
