NOAA was recently a key participant in Earth Day, celebrated at the University of Hawaii-Hilo on April 20th, 2007. Displays provided by NOAA included those of the Mauna Loa Observatory (MLO), the Mokupapa Discovery Center, the PSC Magic Planet, and the National Weather Service Tsunami Center.
MLO had a wide variety of displays at Earth Day, including charts and important results from its 50 year history of measuring atmospheric consituents, hands on demonstrations of instruments such as a carbon dioxide sensor and a lidar laser, live remote-control web cameras showing the observatory, and much more. Many of these displays are shown below.
The carbon dioxide concentration detector allowed people to learn about the co2 they exhale, and the relationship between plants and animals.
The NOAA Pacific Tsunami Warning Center and National Weather Service worked together to education the public about tsunamis.
