The mission of the National Environmental Satellite, Data and Information Service (NESDIS) to provide "timely access to global environmental data from satellites and other sources to promote, protect & enhance the Nation's economy, security, environment & quality of life." Along with their regular research work, they also maintain this website which contains resources within NESDIS and NOAA that are of interest to students, educators, and others with a general interest in the "Earth-Sun environment". Under the "Educational Resources" area, visitors will find an online "weather school" for those interested in learning about the jet stream, a primer on estuaries, and nine other resources. Over in the "Educational Materials" area visitors will find several dozen NOAA Fact Sheets on coral reefs and other matters, along with printable posters for the classroom and visualizations of marine data.
