Earth Day 2022 Air Temperature Data Challenge

Earth Day Air Temperature Data Challenge

Starting on 25 March, and during the four weeks leading up to Earth Day, GLOBE students are encouraged to participate in our global Air Temperature (AT) Data Challenge. The challenge entails a one-day AT collection event that will take place around the world on 25 March, followed by a series of activities throughout the following month focused on visualizing and connecting this worldwide air temperature data.

Check out the results of this year's AT Data Challenge!


On 25 March, go outside and gather an (AT) measurement following the GLOBE AT protocol. Make sure you collect this measurement within one hour of solar noon, local time. During the collection event, remember to: 

  • Take an outdoor photo of yourself or your friends collecting AT data on 25 March
  • Submit your AT measurement into the GLOBE Data Entry System

Important: To participate in the data collection process, you must collect your AT data on March 25, exactly 4 weeks before Earth Day. After you collect your data, you'll have three days to submit your result with a deadline of 28 March.


On 28 March, you can begin examining the data you collected along with all the other measurements gathered by the GLOBE community during the collection event. Additionally, between 28 March and 6 April you can have fun creating a visual representation of all the AT data gathered on 25 March from around the world. These representations can be graphs, drawings, or any other means you choose to visually express the air temperature data. If you need help with this activity, please see the instructions below. 

Note: Creating a data visualization for the collected AT data is an optional activity. 


Collecting and visualizing data is even more rewarding when we connect with others in the GLOBE community to explore the collected AT measurements from around the world. Through this data challenge students are connecting through a shared measurement and how they choose to visualize or “see” the results and share them with the broader community. Keep a look out for featured GLOBE student photographs and visualizations at the GLOBE Earth Day Celebration on 22 April!

Note: The submission window for the AT Data Challenge is now closed.
