Description: The instantaneous net ecosystem exchange of CO2 is shown projected onto the land surface from a Carbon-Land Model Intercomparison Project (C-LAMP) simulation during July 2004 as the sun rises over North America. Green represents an uptake by the biosphere because of photosynthesis where the sun has risen, while red represents a net flux to the atmosphere, dominated by heterotrophic respiration, where it is nighttime.

Description: The instantaneous net ecosystem exchange (NEE) of CO2 is shown as colors projected onto the land surface from a C-LAMP simulation during July 2004. Green represents an uptake by the biosphere (negative NEE) while red represented a net flux into the atmosphere (positive NEE). Click to view larger image.

Description: As the sun rises over Eastern Europe, the instantaneous net ecosystem exchange (NEE) of CO2 is shown in the Eastern Hemisphere. Strong uptake is shown in green-to-white colors and is strongest in the tropics. A net release of CO2 to the atmosphere is shown in red-to-white colors and is strongest over the Congo, where the sun is not shining. This image was produced from a Carbon-Land Model Intercomparison Project (C-LAMP) simulation performed as part of SciDAC2 project on NCCS supercomputers.

Description: The CO2 tracer originating from the land surface is shown as a red cloud. This tracer is the product of the net ecosystem exchange (NEE) between the biosphere and the atmosphere, and it is advected in the atmosphere. The color shown on the land surface depicts the instantaneous NEE source term from this simulation from the Community Climate System Model Verison 3 (CCSM3). Click to view larger image.

Description: 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.
