It’s January! The First Trees Around the GLOBE Student Research Campaign Intensive Observation Period Is On!

The January Intensive Observation Period (IOP) for the Trees Around the GLOBE Student Research Campaign is on!  This is the first of four IOPs that will be held during the campaign: January 2019, Tree Height; April 2019, Land Cover; July 2019, Tree Height; and October 2019, Land Cover.

During this IOP, students will:

  • take measurements of tree height and one additional protocol (from the suite of campaign protocols found at:;
  • take measurements at least three times per week for one month at the same study site for both protocols (tree height measurements should be of the same trees each time for each site; there can be multiple sites, thereby increasing the number of trees measured);
  • report the number of tree height measurements and identify the additional protocol measurement and number of measurements by the fifth day of the following month. 

Every participant will receive a Virtual Tree height IOP Badge!

The GLOBE school with the most collected tree height data and additional protocol data will receive:

  • a Virtual Tree Height IOP Winner Badge
  • a virtual one-on-one Q&A session with a NASA scientist, researcher, or engineer.

The primary goal of this IOP is to have students compare their measurements seasonally and with other GLOBE school measurements from around the world.

The Trees Around the GLOBE campaign is working in conjunction with NASA’s ICESat-2, which is using lasers and a very precise detection instrument to measure the elevation of Earth’s surface. By timing how long it takes laser beams to travel from the satellite to Earth and back, scientists can calculate the height of glaciers, sea ice, forests, lakes and more – including the changing ice sheets of Greenland and Antarctica. The satellite is also measuring tree heights across Earth's temperate and tropical regions, and take stock of the vegetation in forests worldwide.

The campaign is focusing on one exciting variable that the ICESat-2 satellite is measuring: tree height. The campaign is creating an organized community of students who take tree height measurements; compare these measurements to established NASA programs; research tree height data from other GLOBE schools and countries; and take supplemental protocol measurements. Participants will be able to compare their tree height data to the tree height data from ICESat-2. In addition, scientists from the ICESat-2 mission will periodically review the tree height data. This data will allow scientists to use it as satellite data validation and in potential professional research.
