Description

CoastWatch is a nationwide National Oceanic and Atmospheric Administration (NOAA) program within which the Great Lakes Environmental Research Laboratory (GLERL) functions as the Great Lakes regional node. In this capacity, GLERL obtains, produces, and delivers environmental data and products for near real-time observation of the Great Lakes to support environmental science, decision making, and supporting research. This is achieved by providing access to near real-time and retrospective satellite observations and in-situ Great Lakes data. The goals and objectives of the CoastWatch Great Lakes Program directly support NOAA's statutory responsibilities in estuarine and marine science living marine resource protection, and ecosystem monitoring and management. The CoastWatch node at GLERL provides clients including Federal, state, and local agencies, academic institutions, commercial/industries and the public, both within and outside of the Great Lakes region, with access to near real-time satellite observations and in-situ data for the Great Lakes. CoastWatch data are used in a variety of ways, including near real-time observation and tracking of algal blooms, plumes, ice cover, wind, water intake temperatures at fish hatcheries, two and three dimensional modeling of Great Lakes physical parameters such as wave height and currents damage assessment modeling, research, and educational and recreational activities. In addition, through a cooperative project with Michigan Sea Grant, Great Lakes CoastWatch satellite-derived surface temperature imagery is contoured and made available via Michigan State Sea Grant's web site. Great Lakes CoastWatch data and products benefit riparians as well as commercial and recreational users. GLERL is currently receiving a product suite of 33 enhanced digital images including satellite-derived surface temperature (Fig. 1.1), visible and near-infrared reflectance, brightness temperatures, cloud masks, and satellite/solar zenith angle data from the NOAA/AVHRR (Advanced Very High Resolution Radiometer) series of satellites as well as GOES (Geostationary Operational Environmental Satellites) visible, near infrared, and water vapor data. These products are acquired by GLERL from NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) on a daily schedule via Internet. In addition, MODIS true color 250m resolution imagery (Fig. 1.2) of each Great Lake (received near real-time from the Space Science and Engineering Center at the University of Wisconsin), in-situ and modeled data, including marine and meteorological observations, buoy observations, water level gauge measurements from NOAA's National Ocean Service, and Great Lakes Surface Environmental Analysis (GLSEA) composite charts (Fig. 1.3), are routinely acquired or produced, stored, and made available to Great Lakes CoastWatch data users. Great Lakes Forecasting system (nowcast and forecast) products are also available to CoastWatch data users. Near real-time AVHRR satellite data for the past 2 weeks are available at GLERL, and access to a retrospective archive that begins in 1990 is available via an Internet link to the NOAA CoastWatch Active Access System at the NESDIS Satellite Active Archive.
