Trees Around the GLOBE Student Research Campaign
Year 4: October 2021 - September 2022
Trees Around the GLOBE 50 Years of Data Challenge
October 2021 begins Year 4 of the Trees Around the GLOBE Student Research Campaign. With participants from, currently, 58 GLOBE countries, the campaign includes students, educators, citizen scientists, subject matter experts, and scientists from six continents. The campaign focuses on tree height, with a close relationship with land cover, greenings, and carbon cycle.
Year 4 will focus on looking at GLOBE data from the last 50 years, in conjunction with the Landsat series of satellites, as well as collaborative efforts among the GLOBE campaigns (European Phenology Campaign, GLOBE Mission Mosquito, and the Urban Heat Island Effect - Surface Temperature Field Campaign) and where the campaign measurements and observations can overlap and provide participants with an amazing, cross-campaigns, robust dataset.
This year, the campaign will focus deep on getting students really focused on the trees and land cover in their local regions by taking a detailed look at the characteristics in every land cover and tree height photo they take, researching their areas from the last 50 years, and learning how to truly do online comparison of GLOBE and satellite, airborne, and instrument data of land cover, tree height, and greenings.
As an example, what are all the things (characteristics) that you see in the photograph below?
What types of land cover do you see? Do you see trees? How many different types of trees do you see? Do you see shrubs, grasses, barren land, mountains? We want to be as specific as possible, because all the characteristics you see help document the environment around you!
As you know, one of the major focuses for this campaign is to have students take tree height, land cover, greenings, and carbon cycle and use this data to develop research projects that focus on the environment in their local areas in order to understand the larger picture of how our planet is changing over time.
We will focus on two major online tools for data analysis and comparison of GLOBE data to NASA satellite, airborne, and instrument data for land cover and tree height, all in the context of understanding our planet's carbon cycle.
These online tools are:
Global Forest Canopy Height Tool: A 30-meter spatial resolution global forest canopy height map developed through the integration of the Global Ecosystem Dynamics Investigation (GEDI) lidar forest structure measurements and Landsat analysis-ready data time-series (Landsat ARD).
Global Land Cover Viewer Tool: A way to visualize global land cover change maps and statistics and easily navigate and compare between different areas or years.
The Trees Around the GLOBE Student Research Campaign is leveraging all the great things many of the other GLOBE campaigns are doing. These campaigns include the European Phenology Campaign (focusing on Green Up, Green Down, and identification of trees and vegetation), Urban Heat Island Effect - Surface Temperature Field Campaign (focusing on surface temperatures in urban areas), and GLOBE Mission Mosquito (focusing on mosquito habitats, tree holes, and eradicating these potentially dangerous insects carrying vector-borne disease). There are many parallel GLOBE protocol measurements and observations the Trees Around the GLOBE Student Research Campaign will highlight.
When measurements and observations are taken in a specific location, it is vital to know as many environmental variables as possible, so that you can better understand your local environment.
For instance, if you are taking a tree height observation of a tree in your backyard, it is important to know what else is going on around that tree, environmentally. When taking the tree height, you can observe and take measurements of the land cover, surface temperature, observable mosquito habitats, air temperature, soil moisture and characterization, precipitation, and others that you can measure with GLOBE Program protocols.
How can your measurements and observations benefit science and multiple GLOBE campaigns?
European Phenology Campaign
- Campaign Website: https://www.globe.gov/web/european-phenology-campaign
- What are we asking you to observe and measure? Greenings (Green Up and Green Down) and Tree Identification
- What are we asking you to do? When you take a tree height measurement or observation, please take Greenings - Green Up or Green Down (depending on the season) and if possible, identify the genus and species of the tree you are observing. Learn about the Green Up and Green Down Protocols.
- Why are we asking you to do this? Greenings (Green-Up and Green-Down) measurements help scientists validate satellite estimates of the beginning of the plant growing season in a particular location and by identifying the genus and species of a tree, you can add to the knowledge of global tree distribution.
- *IMPORTANT NOTE: You do not need to be in Europe to take these observations. The Trees Around the GLOBE Student Research Campaign is all around the globe and we would love for you to take these measurements wherever you are.
Urban Heat Island Effect - Surface Temperature Field Campaign
- Campaign Website: https://www.globe.gov/web/surface-temperature-field-campaign
What are we asking you to observe and measure? Urban tree (shaded and non-shaded) surface temperature measurements
What are we asking you to do? When you take a tree height measurement or observation, please take a surface temperature measurement in 1.) the shaded surface under the tree being observed; and 2.) the non-shaded area just outside the shaded area of the tree being observed. Learn about the Surface Temperature Protocol.
Why are we asking you to do this? Trees play a big role in keeping our towns and cities cool and the right amount of tree cover can lower summer daytime temperatures in areas shaded by trees.
GLOBE Mission Mosquito
- Campaign Website: https://www.globe.gov/web/mission-mosquito/overview
What are we asking you to observe and measure? Mosquito habitats and tree holes
- What are we asking you to do? When you take a tree height measurement or observation and you notice a tree hole (a tree hole is a hole in a tree that can have standing water inside it and be a potential mosquito habitat) in the tree you are observing, please take a Mosquito Habitat Observation. Learn about the Mosquito Habitat Protocol.
- Why are we asking you to do this? Tree holes can contain stagnant water that could serve as a breeding ground for mosquitoes carrying potentially deadly diseases like Zika, Dengue, Malaria, among others.
To join the campaign, follow these steps:
- Visit the Campaign Community Page, scroll down, and click the "Join Community" link above the map.
- If you are new to GLOBE and have never taken any protocol measurements, you can complete the e-Trainings for the protocols you would like to use.
- Start taking Biometry Tree Height measurements. Some guidelines for choosing trees to measure:
- Trees measured should be at least 5ft (1.52m) tall;
- Trees measured should be isolated trees or the tallest trees in a large grouping of trees
- Decide which other Protocols you and your students will use to take local environmental measurements.
- Start taking your protocol measurements and submit them to GLOBE through the Data Entry Page.
- Connect with us by attending the campaign Webinars and engage in some discussions with other GLOBE schools, scientists, researchers, and campaign team.
- Work with your students to develop potential research projects using your protocol measurement data and data from other GLOBE schools.
- Collaborate with other GLOBE schools from around the world to strengthen your research experience, which could be part of the GLOBE IVSS.
- Begin and/or contribute to the campaign Discussion Forum.
- Present your measurements and research at a future campaign webinar.
- Just have fun learning all about our planet through GLOBE!

The Trees Around the GLOBE Student Research Campaign commenced on September 15, 2018 in conjunction with NASA's ICESat-2 satellite launch on the same date at 6:02am PDT. This campaign is a student research campaign focusing on tree height - one of the measurements conducted by the ICESat-2 mission. Tree height is not just a measurement - it is a gateway to understanding many things about the environment. The structure of tree canopies, the 3D arrangement of individual trees, has a huge effect on how ecosystems function and cycle through carbon, water, and nutrients.
In order to put the tree height measurements into context, we are recommending students to also take measurements of Land Cover Classification, Green Up / Green Down, and Carbon Cycle. This will allow for data research comparisons among several GLOBE environmental measurements.
