Digital Map of the Great Lakes Surface Water Temperature and Ice Cover - 2009-2010 Continue Tone

The Great Lakes Surface Environmental Analysis (GLSEA) is a digital map of the Great Lakes surface water temperature and ice cover which is produced daily at the NOAA Great Lakes Environmental Research Laboratory - GLERL - http://www.glerl.noaa.gov through the NOAA CoastWatch program - http://coastwatch.glerl.noaa.gov

The lake surface temperatures are derived from NOAA polar-orbiting satellite imagery obtained through the Great Lakes CoastWatch program. The addition of ice cover information was implemented in early 1999, using data provided by the National Ice Center (NIC). Lake surface temperatures are updated daily with information from the cloud-free portions of the previous day's satellite imagery. If no imagery is available, a smoothing algorithm is applied to the previous day's map. Ice information will then be added, using the most recent Great Lakes Ice Analysis produced by NIC, nominally twice per week during the ice season.
