Sunrise Over Americas - Net Ecosystem Exchange

The instantaneous Net Ecosystem Exchange (NEE) a measure of the atmospheric-terrestrial exchange of carbon as simulated with a version of the CCSM3 model that includes a terrestrial carbon modeling capability. The red colored areas in the snapshot show regions for which there is an enhanced uptake of carbon by the terrestrial ecosystem as the sun rises over the western hemisphere during Boreal summer. The lighter green colored areas show regions where there is a net source of carbon to the atmosphere in part due to vegetation respiration. This simulation was conducted as part of the C-LAMP project, an intercomparison activity deigned to evaluate the performance of biogeochemical models when coupled to atmospheric general circulation models.
