Project Summary

The goals of this project are to determine the relative magnitudes, controls, and spatial and temporal variation in trace gas fluxes (H20 and CO2) over spatially heterogeneous agricultural land cover regions of the Central Great Plains and Mid-West regions of the continental USA. We are employing a multi-scale strategy of tower and airborne eddy-flux measurements of surface-atmosphere trace gas fluxes, satellite remote sensing of regional vegetation productivity and ecological modeling of these processes from individual plot to regional scales. The results of this study will provide new protocols linking measurements and understanding of biophysical processes over variable spatial and temporal scales and complex land cover.
