Branch Biogenic Emissions Characterization Field measurements and modeling development to accurately estimate biogenic VOC emissions is the objective of this nationally coordinated program.
Research is conducted in-house and in local forests.
This source is larger than all man-made VOC emissions combined. Estimation of biogenic emissions is critical to assessing regional atmospheric chemistry processes causing tropospheric ozone. Research has shown that biogenic emissions produce NOx limited atmospheric chemistry over the entire Eastern U.S. region. The biogenic emissions model provides comprehensive biogenic VOC estimates for the U.S. and has been validated by field trials to demonstrate close agreement between the model's predictions and air quality measurements. This has been accomplished by performing modeling, measurement, and field and laboratory data analysis activities.
