177 Improving Accuracy and Precision of Soil Carbon and Greenhouse Gas Emission Measurements and Quantification: I

Oral Session
ASA Section: Environmental Quality
Acquiring accurate and precise measurements of soil carbon and greenhouse gas emission are fraught with temporal, spatial, technological and computational challenges.  Methodological strategies, analytical improvement, modeling and statistical approaches are needed to improve both the accuracy and precision of these measurements.  Of particular interest are practical aspects to improve field sampling logistics, sampling schemes, chamber design, best strategies for addressing messy data and missing points, and improving flux calculations. This session is intended to provide a forum for a wide range of approaches that will improve the accuracy and precision of soil carbon and greenhouse gas measurement and quantification.  This session will compliment a workshop planned on improving methods for measuring N2O emissions.
