The Earth is a solar-powered planet. So what happens to clouds when the Sun's light is blocked, even temporarily? If you measure air temperature, how cool is the eclipse? Help us answer these questions and others by collecting citizen science data using the GLOBE Observer app and a thermometer during the Total Solar Eclipse on August 21st, 2017. - Observe how the eclipse changes atmospheric conditions near you - Contribute to a citizen science database used by scientists and students to study the effects of eclipses on the atmosphere - Provide comparison data even if you are not in the path of totality
