Research Interests
My general interest is the study of processes related to climate and cryosphere interaction in polar and alpine regions based on in-situ and satellite measurements, and using climate system modeling to study their sensitivity. In particular I study and evaluate sea level changes and sensitivity studies of large ice sheets using in situ and modeling results. Most of this research is supported by the NASA/NSF initiative called PARCA: Program in Regional
Arctic Climate Assessment.
Current Research
- Variability and Forcing of Climate parameters on the Greenland Ice Sheet (NASA Cryospheric Sciences)
- Climatology of Arctic Canada (NASA Cryospheric Sciences)
- Greenland ice sheet melt climatology based on passive and active microwave satellite data (NASA Cryospheric Sciences)
- Aerosol Cloud Climate Interactions (NASA GSFC)
- Investigation of photochemical transformations within snow and their effect on snow and atmospheric composition (NSF OPP)
- Radiation Climatology of the Greenland Ice Sheet (NASA Cryospheric Sciences)
- Assessment of surface melt of the floating tongue of Petermann Gletscher in northern Greenland (NASA Cryospheric Sciences sand NSF OPP)
