GLOBE Carbon Cycle Resources
These resources compliment GLOBE Carbon Cycle Protocols, Learning Activities, Modeling Activities, and Classroom Experiments. Learn more about the GLOBE Carbon Cycle materials here.
NASA eClips Real World: The Carbon Cycle - Essential for Life on Earth. Learning how carbon is converted through slow- and fast-moving cycles helps us understand how this life-sustaining element moves through the environment. Discover how NASA measures carbon through both field work and satellite imager. Features the GLOBE program!
Trees Around the GLOBE Webinar with Dr. Erika Podest, a research scientist with the Carbon Cycle and Ecosystems Group at the NASA Jet Propulsion Laboratory in California USA, titled "Trees: the Lungs of the Earth; Carbon Cycle Science".
USDA Forest Service Carbon Assessments. The U.S Forest Service is a leader in developing tools for carbon assessment, management, and forest carbon cycle science. Page includes carbon infographics and assessment reports.
All the Biomass on Earth - This very cool graphic from Nautilus Magazine shows all the biomass on Earth broken down by animal group and then compares to biomass in other forms of life.

GLOBE Carbon Protocol FAQ with Dr. Scott Ollinger, PI on the Carbon Cycle Project, UNH
Q: Carbon calculations are based only on the diameter of the three, why is the height of the tree not interesting? What is the point of using GLOBE Observer app for trees if only the diameter is interesting?
Dr. Ollinger: Some allometric equations do indeed use height as well as diameter. It’s generally an improvement, but less common given the effort involved and difficulty in closed-canopy forests. We opted for diameter only, because it’s easier to implement for most teachers and because the objectives didn’t require high levels of precision.
Q: In some places I see biomass in kg, and in others I see g/m2. Why?
Dr. Ollinger: The biomass of a single tree is expressed as a unit of mass (e.g. kg) rather than mass per unit area (g/m2). But when expressing biomass over a whole plot or some area containing multiple trees, units are mass per unit area.
Q: Is this Jenkins diagram something that works also for Finnish trees? Our climate is much more severe and trees are here rather small. (See Jenkins et al. figure here, pg. 19)
Dr. Ollinger: The Jenkins et al. equations were developed using studies conducted across North America, including boreal forest species like Picea mariana. Having said that, using locally derived equations is always good when they’re available. A comparison of the two approaches would be a great project for a class in Finland.
