Measuring CO2 Variance from Interior Alaska Forest

In this video, IARC researcher Yongwon Kim shows the equipment he uses to automatically measure CO2, one of the major greenhouse gases. He uses this data to determine the daily variance of CO2 flux in a black spruce forest in interior Alaska in hopes to predict future changes in CO2.

Boreal black spruce forests typically have relatively open canopies that allow a significant portion of incoming radiation to reach the ground vegetation. Forest floor GPP (Gross Primary Productivity) is thus a potentially important process that can represent a significant portion of C assimilation in such ecosystems and can be as high as 50% on certain days.
