Students observe which types of clouds are visible, how much of the sky is covered by clouds, and the opacity of clouds. They also report on surface and sky conditions, information complementary to the satellite view. Data can be recorded using the free GLOBE Observer app. Find out how to get the app at https://observer.globe.gov/about/get-the-app. More information about the GLOBE (Global Learning & Observations to Benefit the Environment) Program and training opportunities on the GLOBE program website. .
