Welcome to learn how to use Carbon Tree!


At the homepage you can see how our special Scots pine tree is fixing carbon at the SMEAR II measurement station. By setting the date you can observe how carbon fixation changes in the tree according to the season. You can also change environmental conditions by clicking "Set weather". By changing the weather you can study how the different factors drive carbon fixation. Carbon Tree is based on measurements executed at the Hyytiälä Forestry Field Station since 2008.

Watch learning videos and see how to change the weather  and how to set the date for Carbon Tree.


At the website, you will find also an other animation called Transpiration. With this animation, you are able to focus more closely on functions of a plant leaf, and adjust the abiotic environmental factors to see how the leaf reacts to them. You can do the adjustments with sliders locating under the animation. If you can't see these sliders on the bottom of the page, zoom out the page until you see them. The keyboard shortcuts for zooming out are:       

  • Windows and Linux: Press Ctrl ja -.
  • Mac: Press ⌘ ja -

The captions provide more precise information about the pictures on the Carbon Tree website. You can make them visible by hovering cursor over the picture.
