Funded by the National Science Foundation, the Atmospheric Visualization Collection's (AVC) goal "is to develop a digital library collection based on the visualization of atmospheric data." Educators can search through the numerous, fun lesson plans by grade (kindergarten through undergraduate) or keyword. After registering, the Wiki server allows teachers to interactively modify the lesson plans in the Lesson Plan Sandbox. The topics of the activities include cloud characterization; measuring water vapor, cloud heights, and wind; and producing weather reports. Undergraduate and graduate students can learn about research and fellowship opportunities.
