The micrometeorological flux measurement technique known as relaxed eddy accumulation (REA) holds promise as a powerful new tool for ecologists. The more popular eddy covariance (eddy correlation) technique requires the use of sensors that can respond at fast rates (10 Hz), and these are unavailable for many ecologically relevant …

Baldocchi, D.
Forests in the south-eastern United States experienced a prolonged dry spell and above-normal temperatures during the 1995 growing season. During this episode, nearly continuous, …

Harley, P., Guenther, A., Zimmerman, P.
In summer 1992, isoprene emission was measured on intact leaves and branches of Quercus alba (L.) at two heights in a forest canopy. Isoprene emission capacity (measured at 30 °C and a photosynthetic photon flux density of 1000 μmol m−2 s−1) was significantly higher in sun leaves than in shade …

Greco, S., Baldocchi, D. D.
Long-term and direct measurements of CO2 and water vapour exchange are needed over forested ecosystems to determine their net annual fluxes of carbon dioxide and water. Such measurements are also needed to parameterize and test biogeochemical, ecological and hydrological assessment models. Responding to this need, eddy …

Baldocchi, D. D., Vogel, C. A.
Fluxes of carbon dioxide, water vapor and energy were measured above and below a temperate broad-leaved forest and a boreal jack pine (Pinus banksiania Lamb.) forest by the eddy covariance method. The aim of the work was to examine differences between the biological and physical processes that control the fluxes of mass …

Harley, P. C., Baldocchi, D. D.
In order to parametrize a leaf submodel of a canopy level gas-exchange model, a series of photosynthesis and stomatal conductance measurements were made on leaves of white …

Baldocchi, D. D., Harley, P. C.
The scaling of CO2 and water vapour transfer from leaf to canopy dimensions was achieved by integrating mechanistic models for physiological (photosynthesis, stomatal …

Baldocchi, D. D., Meyers, T. P.
The eddy correlation method has great potential for directly measuring trace gas fluxes at the floor of a forest canopy, but a thorough validation study has not been yet conducted. Another appeal of the eddy …

Chason, J. Huston, M. D. D. Baldocchi
Two indirect gap fraction methods for estimating leaf area index (LAI) are compared with estimates
from litterfall collections in a mixed-age oak-hickory forest. One indirect method uses averaged,
direct beam penetration data obtained with a moving tram. The second uses a portable light
sensor system that measures diffuse light …
