Here we have highlighted some of the projects that are technically supported by GAL. Most are coordinated with the ND community to meet their research goals using geospatial techniques. Browse the links to the left to learn more about these exciting projects.

Lake Ontario Thermal Stratification Calibration Using Satellite Imagery

  • Project Period: 2011-Present
  • Contributors: Dr. Dilkushi Pitts and Rumana Reaz Arifin
  • Conference Poster: Rumana Reaz Arifin, Dilkushi A. deA. Pitts, Ashish Sharma, Scott C. James, Harindra J. Fernando. Climate and Common Good Conference, Notre Dame, IN 2013, and 56th Annual Conference on Great Lakes Research (IAGLR 2013), Purdue, IN 2013.

This project is about hydrodynamic modeling of thermal stratification patterns in Lake Ontario. The simulated results (lake temperature) from hydrodynamic model Environmental Fluid Dynamics Code (EFDC), are calibrated using satellite temperature imagery. The difference between observed satellite images and simulated temperatures are obtained by applying raster analysis techniques, within a GIS environment. Differences in temperature are quantified using spatial statistics.
