This July/August, The GLOBE Program invites you to take part in our latest challenge, the Mosquito Habitat Photo Challenge.  >>

Have you ever wondered what happens after you submit your GLOBE Observer data? Citizen science data has many applications and is also incredibly important for scientists who are working in the field of artificial intelligence (AI).  >>

In 2019, you joined us on the trail by submitting more than 18,000 land cover photos from 37 countries during our GO on a Trail challenge. On April 22, a peer-reviewed scientific analysis of the data was published in Frontiers in Climate. The paper summarizes the data submitted during the challenge, describes how your data are matched to satellite-based land cover products and outlines how GLOBE Observer observations could help scientists in the future.  >>

The NASA GLOBE Clouds team at NASA Langley Research Center (LaRC) is working with a team of NASA researchers to use GLOBE Cloud observations made by people just like you to solve the Terminator Problem!  >>

What is the terminator problem? The solar terminator (or “twilight zone”) is the line that separates the daylit side of a planet from the dark night side. From Earth’s surface we can often see lovely sunrises and sunsets at the terminator. However, these same conditions pose some difficulties for cloud-observing satellites.  >>

The most recent GLOBE challenge, the 2021 Community Trees Challenge, has ended. Between April 15 – May 15, around the world, GLOBE and GLOBE Observer citizen scientists took 2,441 tree height observations from 1,733 global locations.  >>

Imagine all the fun of Comic-Con, only with fewer costumes and a more sciency, save-the-planet, get-everyone-doing-science kind of vibe and you have NASA’s inaugural CitSciCon, a virtual event on May 21 and May 22.  >>

Through K10, Girl Scouts can earn a “Clean Water Grows on Trees” fun patch by learning about the importance of trees and their impact on clean water.  >>

The Keystone 10 (K10) Million Trees Partnership is a collaborative effort, in Pennsylvania, of national, regional, state, and local agencies, conservation organizations, outdoors enthusiasts, businesses, and citizens committed to improving Pennsylvania's communities, economy, and ecology.  >>

Tree height is the most widely used indicator of an ecosystem's ability to grow trees, so tracking tree height over time can help us to assess the ecological health of a given area.  >>
