Boreal Forest
Observatory
|
 Canopy CO2 data
are collected as part of a long-term monitoring effort to detect
changes in the Anchorage airshed and boreal ecosystem function and in
support of a study designed to monitor belowground respiration on a
continuous basis throughout the winter.
Variation in CO2
concentrations within the forest canopy reflect the combined effects
of diurnal variation in the depth of the planetary boundary layer,
fossil fuel combustion within the Anchorage bowl, build-up of
ecosystem-respired CO2 within the forest
canopy and periodic atmospheric inversions. |
