Webinars became an important part of the campaign. For spring 2021 we have planned for you a series of webinars focused on a spring tree change and the role of trees in an urban environment. The webinars also provided opportunities for sharing experience and meeting scientists. The webinars were prepared in cooperation with scientists from the Trees Around the GLOBE campaign team. 


2021 Spring Campaign webinars


Thursday, April 15th @ 3 pm CET. Trees in my Neighborhood. 
Meeting with scientists from the Czech Republic, Ukraine and the USA on the topic of growing and caring for trees in cities, the role of trees in reducing the urban heat island and the use of remote sensing to study changes in vegetation. The webinar is organised in cooperation with the Trees Around the GLOBE Campaign team.

The webinar will be organised on ZOOM. To join, please register here


Thursday, May 6th @ 3 pm CET, My Spring Data. Learn how to enter green-up data and how to create a graph of leaf growth using the GLOBE visualisation tool.

Wednesday, June 2nd @ 3 pm CET, Our Spring Research. Online meeting for students and teachers to present their work and inspire each other.


Trees Around the GLOBE Campaign webinars. 


Tuesday, April 20, 2021 @ 5:00pm UTC. Trees are Long Term: Looking back at GLOBE tree data for tree growth and tracking tree growth over time. The webinar will focus on the idea that since trees are long term, we can track the growth of trees over time through ground-based and satellite observations. Highlights will include the new GLOBE Trees Family Guide, the 2021 Trees Community Challenge: Science is Better Together, using online tools to look at tree growth over time, and a call to action for campaign participants, including taking repeat tree height observations of the same trees and finding out where we have gaps in tree height data.
