A Field Investigation Of Sulfate Fluxes To A Deciduous Forest
Hicks, B. B., Matt, D. R., McMillen, R. T., Womack, J. D., Wesely, M. L., Hart, R. L., Cook, D. R., Lindberg, S. E., Depena, R. G., Thomson, D. W.

An intensive investigation of particulate sulfur fluxes to a deciduous forest was conducted at Oak Ridge, Tennessee, during May 1983, as part of a multilaboratory program to study the dry deposition of airborne trace gases and aerosols to vegetated surfaces. At this time, the leaf area was approximately 50% of the maximum and was …

A Numerical Model For Simulating The Radiation Regime Within A Deciduous Forest Canopy
Wang, H., Baldocchi, D. D.

A numerical model that simulates the radiation regime inside a fully leafed and leafless deciduous forest canopy is discussed and tested. The model incorporates features which account for the vertical variation in leaf inclination angles and penumbral effects; these features have been experimentally shown to significantly influence …

Measuring Biosphere-Atmosphere Exchanges Of Biologically Related Gases With Micrometeorological Methods
Baldocchi, D. D., Hicks, B. B., Meyers, T. P.

Ecologists are expected to play an important role in future studies of the biosphere/atmosphere exchange of materials associated with the major biogeochemical cycles and climate. Most studies of material …

Turbulence Structure In A Deciduous Forest
Baldocchi, D. D., Meyers, T. P.

Three-dimensional wind velocity components were measured at two levels above and at six levels within a fully-leafed deciduous forest. Greatest shear occurs in the upper 20% of the canopy, where over 70% of the foliage is concentrated. The turbulence structure …

A Spectral And Lag-Correlation Analysis Of Turbulence In A Deciduous Forest Canopy
Baldocchi, D. D., Meyers, T. P.

The processes influencing turbulence in a deciduous forest and the relevant length and time scales are investigated with spectral and cross-correlation analysis. Wind velocity power spectra were computed from three-dimensional wind velocity measurements …

A Canopy Stomatal Resistance Model For Gaseous Deposition To Vegetated Surfaces
Baldocchi, D. D., Hicks, B. B., Camara, P.

A gaseous deposition model, based on a realistic canopy stomatal resistance submodel, is described, analyzed and tested. This model is designed as one of a hierarchy of simulations, leading up to a “big-leaf” model of the processes contributing to the exchange of trace …

On Estimating Canopy Photosynthesis And Stomatal Conductance In A Deciduous Forest With Clumped Foliage
Baldocchi, D. D., Hutchison, B. A.
The foliage in a fully-leafed deciduous forest canopy is clumped. Consequently, theory indicates that the probability of beam penetration will be estimated more accurately with a model based on the negative binomial distribution than with a model based on the Poisson distribution, incorporating an assumption …

Directional Thermal Infrared Exitance Distributions From A Leafless Deciduous Forest
Balick, L., Hutchinson, B.

The directional thermal infrared exitance distributions of a 21.5-m-tall leafless deciduous forest were measured using a rotating 7-detector array suspended 33 m above the forest floor. These distributions are presented for several illumination conditions. Strong directional thermal infrared distributions were observed at high solar …

Eddy Fluxes Of CO2, Water Vapor, And Sensible Heat Over A Deciduous Forest
Verma, S. B., Baldocchi, D. D., Anderson, D. E., Matt, D. R., Clement, R. J.

Fluxes of CO2, latent heat and sensible heat were measured above a fully-leafed deciduous forest in eastern Tennessee with the eddy correlation technique. These are among the first reported observations over such a surface. The influences of solar …
