NASA scientists are very interested in learning how clouds affect our atmosphere. It is the clouds, in part, that affect the overall temperature and energy balance of the Earth. The more we know about clouds, the more we will know about our Earth as a system. And YOU can help by sending NASA your observations!

NASA S'COOL has now joined forces with the Global Learning and Observations to Benefit the Environment (GLOBE) Program creating a larger community of cloud observers across 120+ countries.

• If you are new to GLOBE:


• Learn how to participate in the NASA GLOBE Cloud Observation Project.
• Teachers may wish to become GLOBE Certified by participating in online eTraining.


• Citizen Science Observations can be submitted through the GLOBE Observer app.

Download the GLOBE Observer app:
For iOS via the App Store
For Android via Google Play

The S'COOL Citizen Science option continues to be available here if you are not able to submit cloud observations through GLOBE.

The buttons to the right will walk you through each participation step! We welcome participation from any interested observers, especially from places where official weather observations are few and far between.
