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.

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.
