In the previous three years, 144 90-second Earth & Sky radio shows have been produced under sponsorship of the National Aeronautics and Space Administration. The impact of these shows was explored with a posttest-only experimental design comparing a treatment group that listened to nine daily NASA shows focused on the topic of Antarctica and a control group that listened to nine daily non-NASA shows about whales. Participants were randomly assigned to groups, which did not differ on the variables of gender, age, ethnicity, education, frequency of hearing Earth & Sky, and interest in hearing
NASA cloud observation project. Ground observation reports are compared to cloud information retrieved from satellite instruments in Earth orbit. Learn how to make and report a cloud observation at the time of a satellite overpass. Observations welcome from any interested observers, especially in places where official weather observations are rare. Get satellite overpass times, learn about making observations, report an observation, and explore the database of reported observations (which includes corresponding satellite data once they are available).
