April 1, 2016VIIRS 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.

August 30, 2002New CoastWatch Archive Site at SAAAt the end of July the SAA roled out software version 3.2 (CLASS V.0). Included in this release was a unified user interface to include NCAAS, subscription accounts for NCAAS users, and search capablility to include multiple sub-regions. Currently the SAA is maintaining both NCAAS and SAA/NCAAS web sites (will eliminate NCAAS by the end of September). When accessing the NCAAS web site the following message appears:The SAA has started its transition to becoming the Comprehensive Large Array-data Stewardship System (CLASS) by combining the SAA Web Interface Gateway (SWIG), NOAA Coast Watch Active Access System (NCAAS), and Live Active Server (LAS) into a single web interface. It is now available for your use at www.saa.noaa.gov.

August 1, 2001CoastWatch Data Analysis Tool (CDAT)The CoastWatch Data Analysis Tool (CDAT) is a data visualization program with a graphical interface that allows users to view and perform simple analysis on CoastWatch and other satellite data. CDAT is currently under development, but is available in a number of versions for Unix and Windows platforms.April 2, 2001Goes SST ImageryA new water surface temperature image product derived from NOAA's Geoststionary Operational Environmental Satellites (GOES) has been introduced on the Great Lakes CoastWatch web site (http://coastwatch.glerl.noaa.gov/goes/goes_sst.php). A 3-hour composite image produced by combining three separate images, each created 1-hour apart, and retaining the most recent temperature value is shown using color to depict temperature values.February 28, 2001NOAA-16 ImageryThe Great Lakes CoastWatch node began receiving NOAA-16 AVHRR satellite imagery on Thursday February 22nd. The initial daytime image [g0105318.ld1] was received at 14:33 EST on 2/22, and the initial nighttime image [g0105407.ls7] at 03:02 EST on Friday 2/23.CWFTOARC Software AvailableThe cwftoarc utility converts CoastWatch data files to either an ASCII or binary GRID file for use in the ArcView or ARC/INFO GIS packages from Environmental Systems Research Institute, Inc.

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.
