The Earth and Sky radio series proposes to produce, distribute, market and evaluate 72 compelling environmental radio programs on oceanic and atmospheric topics featuring NOAA scientists, data and information. These programs will air at a rate of 24 programs per year over a three-year period as part of Earth and Sky's regularly scheduled programming to its many affiliates. Earth and Sky will feature this new radio programming on our web site. The programs will be available in both text and a variety of audio formats including downloadable mp3 files, streaming m3u files, and will be available for podcast. The web site will also feature additional information that augments and supports the content of the radio programs, including links to relevant information, encouraging web visitors to delve deeper into a topic area and learn more. Project Learning Tree (PLT) is an award-winning environmental education program designed for teachers and other educators, parents, and community leaders working with youth from preschool through grade 12. PLT will correlate their vast catalogue of existing environmental education curricula to each show. Correlations for each program will be listed next to that show in the dedicated PLT section of Earth and Sky's website.
