Chu, H., Baldocchi, D. D., Poindexter, C., Abraha, M., Desai, A. R., Bohrer, G., Arain, M. A., Griffis, T., Blanken, P. D., O'Halloran, T. L., Thomas, R. Q., Zhang, Q., Burns, S. P., Frank, J.

Aerodynamic canopy height (ha) is the effective height of vegetation canopy for its influence on atmospheric fluxes and is a key parameter of surface‐atmosphere coupling. However, methods to estimate ha from data are limited. This synthesis evaluates the applicability and robustness of the calculation of ha from eddy covariance …

Does day and night sampling reduce spurious correlation between canopy photosynthesis and ecosystem respiration?
Dennis Baldocchi, Cove Sturtevant

It is necessary to partition eddy covariance measurements of carbon dioxide exchange into its offsetting gross fluxes, canopy photosynthesis, and ecosystem respiration, to understand the biophysical controls on the net fluxes. And independent estimates of canopy photosynthesis (G) and ecosystem respiration (R) are needed to validate …

Controls On Carbon Dynamics By Ecosystem Structure And Climate For Southeastern U.S. Slash Pine Plantations
Bracho, R., Starr, G., Gholz, H. L., Martin, T. A., Cropper, W. P., Loescher, H. W.

Abstract. Planted pine forests (plantations) in the southeastern United States are an
important component of the continent’s carbon balance. Forest carbon dynamics are affected
by a range of factors including climatic variability. Multiyear droughts have affected the
region in the past, and an increase in the frequency of drought …

Carbon Dynamics Along A Chronosequence Of Slash Pine Plantations In North Florida
Clark, K. L., Gholz, H. L., Castro, M. S.

To determine factors controlling the carbon dynamics of an intensively managed landscape, we measured net CO2 exchange with the atmosphere using eddy covariance and soil CO2 fluxes using static chambers along a chronosequence of slash pine (Pinus elliottii var.

Energy Exchange Across A Chronosequence Of Slash Pine Forests In Florida
Gholz, H. L., Clark, K. L.

We measured net atmospheric exchanges of energy and water vapor using eddy covariance along a chronosequence of Pinus elliottii plantations in north Florida: a recent clear-cut, a mid-rotation stand, and a 24-year-old, rotation-aged stand. Reflected energy averaged 0.26 of incoming solar radiation at the clear-cut and 0.18 …

Effects Of Forest Harvesting On Soil Methane Fluxes In Florida Slash Pine Plantations
Castro, M. S., Gholz, H. L., Clark, K. L., Steudler, P. A.

We examined the effects of forest harvesting on the net exchange of methane (CH4) between the atmosphere and sandy soils in two mature slash pine (Pinus elliottii Engelm. var. elliottii) plantations in northern Florida. Before each of the stem-only harvests, soils in these plantations were net sinks for CH4

A Model For Soil CO2 Production And Transport 2: Application To A Florida Pinus Elliotte Plantation
Moncrieff, J. B., Fang, C.

In this paper, the one-dimensional, process-based soil CO2 model (PATCIS) described in Part 1 is parameterized and validated with field data collected in a mature slash pine plantation in Florida. The results of a model sensitivity analysis show that CO2

Simple And Fast Technique To Measure CO2 Profiles In Soil
Fang, C., Moncrieff, J.

We describe a simple method for sampling soil gas at different profile depths and analyzing CO2 concentration in the gas sample. Soil gas samples were taken on the soil surface from each chosen depth through a gas circulation system and analyzed in situ
