The
carbon dioxide transport at the Niwot Ridge AmeriFlux site was investigated in
both gravity and streamline coordinates. For this forested site with a 6%
slope, both nighttime drainage flow and daytime upslope flow played important
roles in the CO2 budget. Both the CO2 respiration at
night and the CO2 uptake during the day are underestimated if the
horizontal transport of CO2 is not monitored; and the two components
may not cancel out.
