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 …

Baldocchi, D., Hutchison, B., Matt, D., McMillen, R.
The seasonal variability in the frequency distribution (FD) and higher order moments (e.g., standard deviation, skewness and kurtosis) of photosynthetically active radiation (PAR) penetration in an oak—hickory forest were examined. In a leafless, wintertime forest the …

Baldocchi, D., Hutchison, B., Matt, D., McMillen, R.
Seasonal variations in solar elevation, canopy phenology and leaf pigmentation result in a dynamic variation in the radiation regime within a deciduous forest. Measurements of several insolation components taken within an east Tennessee oak-hickory forest during eight combinations of season and phenological conditions of …

Baldocchi, D., Matt, D., Hutchison, B., Mcmillen, R.
Global shortwave, photosynthetically active, net and allwave radiation was measured above, and at several levels within an oak—hickory forest with instruments mounted on a moving tram system. Profiles of radiation flux densities were quantified using extinction coefficients based on the Beer—Bouguer law. Data are reported …

Luxmoore, R. J.
Soil water content and soil matric potential were monitored during 2 years at two neighboring ridge-top sites in an oak-hickory stand on a Typic Paleudult forest soil with cherty silt loam texture. Hydraulic gradients and soil water contents showed distinct seasonal variation. Soil water dynamics and water budgets were simulated …

Richter, D. D., Johnson, D. W., Todd, D. E.
In the 1981 water year, bulk precipitation was primarily a solution of dilute H2SO4, and SO42-was the dominant anion in tbroughfall and soil leachates in two eastern Tennessee deciduous forests. Ecosystem inputs of SO42-, which included dry deposition of forest canopies, …

Lindberg, S. E., Harriss, R. C., Turner, R. R.
Atmospheric deposition during the growing season contributes one-third or more of the estimated total flux of lead, zinc, and cadium from the forest canopy to soils beneath an oak stand in the Tennessee Valley but less than 10 percent of the flux of manganese. The ratio of the wet to dry deposition flux to the vegetation during this …

Luxmoore, R. J., Grizzard, T., Patterson, M. R.
Soil hydraulic properties at eight depths in a Fullerton cherty silt loam (a clayey, kaolinitic, thermic Typic Paleudult) profile were derived from measurements of water content with a calibrated neutron probe and of matric potential with tensiometers during drainage of a flooded 2- by 2- by 3-m deep soil plot. Soil cores taken from …

Lindberg, S. E., Harriss, R. C.
Atmospheric sources contributed significantly to the annual flux of trace metals and sulfate to the forest floor of Walker Branch Watershed, a forested catchment in the southeastern United States. Atmospheric deposition supplied from 14% (Mn) to≈40% (Zn, …
