Today (14 May): Trees Around the GLOBE Campaign Webinar “What Greens Up, Must Green Down – Greenings Live from Switzerland”
On Tuesday, 14 May, the Trees Around the GLOBE Student Research Campaign webinar “What Greens Up, Must Green Down – Greenings Live from Switzerland,” will be held at 12:00 p.m. EDT (4:00 p.m. UTC).
GLOBE Master Trainer, Markus Eugster, and his students from the Sekundarschule Uzwil in Switzerland, have been conducting Greenings (Green-Up and Green-Down) research during their tree investigations. Monitoring the beginning and ending of the growing season of trees helps scientists track plant growing seasons. One way to track the change is through a Swiss GLOBE program called PhenoCam, which is a way to use automated cameras to take images of trees and create time-lapse videos and run color analysis of the trees over time.

The Trees Around the GLOBE Campaign
The Trees Around the GLOBE campaign is working in conjunction with NASA’s ICESat-2. ICESat-2 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.
