VIIRS Satellite SST Data Included in the Great Lakes Surface Environmental Analysis (GLSEA)VIIRS Satellite SST data (1024x1024) has been added to Great Lakes Surface Environmental Analysis. The GLSEA is produced daily from near real-time, cloud masked and mapped satellite AVHRR and VIIRS SST data using the new compositing algorithm (2007). Ice cover concentration from the Great Lakes Ice Analysis produced by the National Ice Center (NIC) is overlaid during winter months.

The Great Lakes CoastWatch node located at the Great Lakes Environmental Research Laboratory (GLERL) in Ann Arbor, MI announces the availability of its newly reconstructed web site at: http://coastwatch.glerl.noaa.gov The new web site has numerous features, utilities, and data types including:
-- all Great Lakes CoastWatch satellite (AVHRR) temperature and reflectance data available for viewing and download via the web site.
-- SatView - a Java based interactive analysis tool for CoastWatch AVHRR temperature and reflectance imagery.
-- the Great Lakes Surface Environmental Analysis (GLSEA) composite temperature chart has winter ice cover concentration (from the National Ice Center (NIC) Great Lakes Ice Analysis).
-- yearly and last 365 day animation's of the daily GLSEA chart in QT, FLC, and AVI formats.
-- Great Lakes Forecasting System nowcasts and forecasts of numerous lake parameters (currents, wave height, etc.).
-- links to numerous web sites for complimentary data including Great Lakes bathymetry, water levels, buoy data, weather data, etc.
As in the past, Great Lakes CoastWatch continues to supply Michigan Sea Grant with near real-time satellite imagery for its contoured water surface temperature product, available via a link to the Michigan Sea Grant web site.
A signed Memorandum of Agreement (MOA) is no longer needed to access CoastWatch near real-time satellite (AVHRR) imagery. Currently, only a username and password, which can be generated and obtained interactively upon visiting the web site, are necessary for access. Your username and password are valid for all future access. (Note: RADARSAT imagery has limited access owing to the proprietary nature of this data.). Other data types and products do not require a username and password for access.
Although still under construction, our goal is to develop a comprehensive web site for access to near real-time and retrospective satellite and in situ environmental data and products to meet the needs of various users for environmental monitoring, decision making, research, and recreational uses.
