GLOBE 2019 Fall Cloud Challenge Rakes in the Observations! A Big “Thank You” to all Participants!
The GLOBE 2019 Fall Cloud Observation Challenge, which ran from 15 October through 15 November, has wrapped up. The challenge brought in more than 45,000 observations from citizen scientists in more than 17,000 locations in 93 countries on every continent — including Antarctica.
This influx of cloud observations is helping scientists who work with geostationary satellites and the suite of satellite instruments known as the Clouds and the Earth's Energy Radiant System (CERES). By comparing geostationary and CERES observations from a particular area to data submitted by citizen scientists, scientists can differentiate between wispy cirrus clouds and cold, bright features on the ground such as snow.
