SPoRT is preparing a high resolution water temperature product for the Great Lakes region as subset of the enhanced MODIS/AMSR-E SST composite (beta version released last month). The example below shows significant detail in the surface water temperature structure across sections of each lake. Forecasters use this information in a diagnostic mode and prognostically (in weather forecast models) to improve the prediction of clouds and precipitation in the Great Lakes region. This will have significant impact in Lake effect snow situations.
The product will be available for use in the WRF EMS v3 and in AWIPS early next year.
