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.  >>

With the GLOBE Observer (GO) mobile app there are two ways of tracking the location and number of trees across Earth: GO Land Cover and GO Trees. So what is the difference between these two? What is the benefit of one over the other? Should you make observations of trees using both of the tools?  >>

The options available through the GLOBE Program can be complex, and it can be difficult for teachers or other educators to determine the best way to use GLOBE Observer with their students or program participants. Different choices will make sense in different circumstances. This article describes some of the main options with GLOBE, and what each one can and can’t do, with a particular focus on how they might work for teachers or other facilitators running programs for students, or students and families.  >>

The website’s upgrade transition period is planned for 12 November through 16 November. During this period, sign in to the site will be turned off, and as such, users will not be able to add data. For the GLOBE Observer app, users will not be able to submit data within the app. However, users will still be able to make and store observations on the app to be uploaded to the site at a later time (after the upgrade is complete).  >>

2020 is now the costliest year on record for natural disasters in the United States. And yet scientists predict that extreme Earth events will become more frequent and more powerful as the climate warms  >>

GLOBE has been hard at work behind the scenes creating new tools and resources to make it even easier to use GLOBE data in your research. Learn more about the new resources GLOBE has launched in the last year to make it easier to do your science.  >>

Over the course of 2019, you helped us collect data, observe an eclipse, GO on a Trail, do research, and make new friends.  >>

To better understand the route’s current land cover conditions, this summer, we asked people to take pictures of the land cover along this area of interest, using the GLOBE Observer App. The GO on a Trail data challenge began June 1 and ended on September 2, 2019. Thus far, participating GLOBE observers have collected and submitted hundreds of observations along the Lewis and Clark route.  >>

ou may have heard the news- there is an exciting challenge this summer for GLOBE Observer users! The challenge follows in the spirit of early cartographers, Meriwether Lewis and William Clark, and you can win one of two ways. First, use GLOBE Observer to map as much land cover as possible in any GLOBE country by September 2. The top data collectors in each GLOBE region will be recognized. Or, for U.S. users, head to the Lewis and Clark National Historic Trail between Pittsburgh, PA and the Oregon Coast, and take Land Cover and Mosquito Habitat Mapper observations using the GLOBE Observer app. This 3 month campaign kicks off on National Trails Day (June1) and concludes on Labor Day (Sept 2). Each observation you make along the trail will increase your chances to be one of our top observers and be eligible for a prize package.

Are you participating in our GO on a Trail Challenge? To join, just use your GLOBE Observer app to take as many land cover observations as you can. You can get points toward winning two ways: collect observations on the Lewis and Clark Trail or collect observations in any GLOBE country.  >>
