The challenge is now complete! See the results and the names of the top observers here.


The NASA GLOBE Clouds Team at NASA Langley Research Center in Hampton, VA is excited to announce the NASA GLOBE Clouds Fall Data Challenge. Participants are invited to enter up to 10 observations per day of clouds, dust, haze or smoke from October 15, 2019 to November 15, 2019. Participants can enter their data using any of GLOBE’s data entry tools including the clouds tool on the GLOBE Observer citizen science mobile app. As a reward, the GLOBE and GLOBE Observer participants with the most observations will be congratulated by NASA scientists with a video posted on the NASA GLOBE Clouds website. Only those that enter their cloud observations using the GLOBE Online Data Entry website, GLOBE Data Entry app, or the GLOBE Observer app will be considered.


Tell us what you see in your sky. Tips are available to help you distinguish between clouds and obscurations.


Do you see clouds? Use these steps to make the observation. Find tips and resources are available at the bottom.


Do you see a dust storm, haze, or smoke? We want your photographs! Use the steps recommended to capture a dust storms. Example images are available to guide you to identify what you are looking at. Please note that a gray looking day might be a sky that is completely covered by clouds. Want to learn more about dust storms? Use our Dust Observations section on our NASA GLOBE Clouds website to learn more about your impact and review educator resources on the topic.



NASA Will Match Your Observation to Satellite Data from Space

NASA matches GLOBE Cloud observations submitted to various satellite data! To increase your chances of getting a satellite match to your observations by using the satellite notification option on the GLOBE Observer app or use the satellite overpass website to see the schedule when satellites will be right over your location. If your observation is made within 15 minutes (either before or after) the time a satellite will be over your area, you have increased the chances of getting a personalized email from NASA comparing your observations to satellites! Satellites that you could match to include geostationary satellites, Terra, Aqua, and CALIPSO


We hope you participate in this data challenge. Your observations help scientists better understand satellite data of our atmosphere.




Make Land Cover Observations: What is on the ground can impact what you may see in the sky. Learn more about the land cover and collect your observations using the GLOBE Observer app!
