New Research on the Impact of Pressure Perturbation on Chamber-Based Soil CO2 Flux Measurements Presented at AGU Annual Meeting
January 4, 2005 - Lincoln, NE
LI-COR Biosciences presented new research at the December 2004 meeting of the American Geophysical Union in San Francisco , California .
The presentation focused on new research and technology designed exclusively for the new LI-8100 Automated Soil CO2 Flux System. More specifically, it is shown that (1) soil CO2 flux measurement is sensitive to small pressure changes, (2) the variation in natural wind leads to substantial chamber pressure excursions from ambient with or without a vent, and (3) a new pressure vent design (patent pending) used exclusively with the LI-8100 eliminates chamber pressure differentials between chamber and ambient air over a wide range of wind speeds.
