New Soil CO2 Flux Research: Equalizing Pressures Under Windy Conditions

May 9, 2005 - Lincoln, NE

New Research on Equalizing Pressures Between A Soil CO2 Flux Chamber and the Ambient Air Under Windy Conditions Presented at EGU Annual Meeting

Wind can cause negative pressure excursions in vented chambers, which can lead to large over-estimates of soil CO2 flux. Now a new pressure vent design from LI-COR Biosciences virtually eliminates chamber pressure differentials between the chamber and ambient air over a wide range of wind speeds. LI-COR presented research on the new pressure vent design at the April 2005 meeting of the European Geosciences Union in Vienna, Austria.
