310 Physical Aspects of Quantifying and Predicting Greenhouse Gases Emissions From Soils

Oral Session
S01 Soil Physics
The goals of this session are to emphasize the need in better understanding of the complex gaseous transport processes occurring in soil-atmosphere continuum, and to present and discuss the utility of various measurement tools and modeling techniques for quantifying and assessing gas transport processes.
