Abstract
In January 1997, the Students’ Cloud Observations Online (S’COOL; http://scool.larc.nasa.gov) project began with NASA scientists visiting rural Gloucester, Virginia, to observe clouds with middle school students. In the nearly 20 years since, this educational outreach component of NASA’s Clouds and the Earth’s Radiant Energy System (CERES) mission has collected ∼144,500 observations from every continent and ocean basin around the world. Thousands of students, educators, and cloud-watching enthusiasts have participated in S’COOL.
More than half of S’COOL observation reports correspond to one or more CERES overpasses. A thorough analysis of collocated S’COOL and satellite data were conducted during summer 2015. Results showed that the S’COOL community reports high-quality observations providing useful insights on the strengths and shortcomings of passive cloud remote sensing from space. This reconfirms the utility of S’COOL observations to the scientific community and enables deeper insight into challenges associated with validation of space-based cloud property retrievals.
To maintain long-term participation, S’COOL has added components that involve participants directly with science data analysis, strengthening ties to CERES research and deepening engagement. Whenever possible, the S’COOL team sends corresponding subsets of CERES data for the participant to compare to their report. Observations can now be matched to images and cloud retrievals from multiple satellites and instruments. Recent connections to geostationary data make cloud observations at almost any time of day over nonpolar regions useful for validation. This attention to inviting participants into an authentic science experience is key to the long-term success of the project.

Abstract
Citizen science is often recognized for its potential to directly engage the public in science, and is uniquely positioned to support and extend participants’ learning in science. In March 2018, the Global Learning and Observations to Benefit the Environment (GLOBE) Program, NASA’s largest and longest-lasting citizen science program about Earth, organized a month-long event that asked people around the world to contribute daily cloud observations and photographs of the sky (15 March–15 April 2018). What was considered a simple engagement activity turned into an unprecedented worldwide event that garnered major public interest and media recognition, collecting over 55,000 observations from 99 different countries, in more than 15,000 locations, on every continent including Antarctica. The event was called the “Spring Cloud Challenge” and was created to 1) engage the general public in the scientific process and promote the use of the GLOBE Observer app, 2) collect ground-based visual observations of varying cloud types during boreal spring, and 3) increase the number and locations of ground-based visual cloud observations collocated with cloud-observing satellites. The event resulted in roughly 3 times more observations than during the historic and highly publicized 2017 North American total solar eclipse. The dataset also includes observations over the Drake Passage in Antarctica and reports from intense Saharan dust events. This article describes how the challenge was crafted, outreach to volunteer scientists around the world, details of the data collected, and impact of the data.
