| On a dusky winter's evening at the Mesa Lab, a glimmer of spring can be found underneath the main entrance in the Frost Phytotron. The climate-controlled room is home to a set of tiny peat bogs and a group of potted oak, spruce, and pine trees. The plants are studied year-round by the Atmospheric Chemistry Division to assess how changes in atmospheric composition affect the biosphere. Denver's Frost Foundation, who provided a grant for construction of the phytroton several years ago, has also paid for a photosynthesis measurement system and a mini-rhizotron, which measures root growth and biomass.
