Research Interests

Remote sensing of snow, ice, and frozen ground; snow cover and glacier mass/extent as indicators of climate change; properties of avalanche snow; data set and cryospheric product development

Current Research Projects

  • Enhancing methods to map global snow cover by combining optical data from MODIS and passive microwave data from AMSR-E
  • Mapping glaciers at two spatial resolutions using data from ASTER (60 m) and MODIS (500 m)
  • Investigating temporal and spatial snow cover distribution over the Tibetan Plateau and the synoptic patterns contributing to extreme winter snowfall events
  • Studying microwave sensor calibration: Developing a systematic method to evaluate the spatial and temporal variability of brightness temperatures over selected land surface types (ice sheets and tropical forests) to locate stable calibration targets
  • Managing the NSIDC "State of the Cryosphere" Web site
  • Passive Microwave Snow Cover Algorithm Intercomparison and Validation
  • Investigation of the Seasonal Freeze/Thaw Cycle of Soils in the GEWEX American Prediction Program Regions
  • A Regional, Integrated Monitoring System for the Hydrology of the Pan-Arctic Land Mass
