Research interests
Remote sensing of snow, ice, and frozen ground; physical and mechanical properties of snow; snow cover and glacier mass/extent as indicators of climate change
              
Recent Highlights and Upcoming Expeditions
October 2007: The Intergovernmental Panel on Climate Change (IPCC) was named to receive the 2007 Nobel Peace Prize, along with former Vice President Al Gore. Armstrong contributed to the most recent IPCC report, Climate Change 2007: The Physical Science Basis.
Developed and distributed a global snow extent and snow water equivalent data set for 1987 to 2005
         
Current Research
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
