New Carbon Flux Super Site: Innovative Methods of Atmosphere-Terrestrial Carbon Exchange Measurements and Modeling LEAP Lab, UGA/ SRNL / BNL / NOAA / Univ. of Iowa / Duke Univ. / SREL, UGA Introduction We propose a suite of powerful site cross-cutting methods for reducing uncertainties in current CO2 flux measurements. Carbon Flux Super Site: 1) Located in one of the most productive regions of the US. 2) Presents a genuine opportunity to refine our understanding and measurement methods of carbon uptakes. 3) Provides additional insight into surface exchange mechanism especially in non-ideal conditions. The integrated team work combines forward and inverse regional modeling to spatio-temporal interpretation of improved flux measurements obtained from airborne and stationary flux platforms. Goal: To produce new, improved and scientifically more accurate estimate of atmosphere-terrestrial ecosystem exchange processes. Aims: 1. To determine nocturnal atmospheric footprint estimation and validation 2. To characterize flow anomalies in stable boundary layers 3. To examine the importance of atmospheric low-level jets on local and regional fluxes 4. To provide a quantitative, spatially, and temporally resolved description of carbon, water, and energy exchange at the regional scale. 5. To validate a recently developed, alternate method of measuring fluxes for conditions where eddy-covariance flux measurements are unreliable.
