The Dynamic Role Of Root-Water Uptake In Coupling Potential To Actual Transpiration
Lai, C., Katul, G.

The relationship between actual (Eact) and potential (Ep) transpiration above a grass-covered forest clearing was investigated numerically and experimentally from simultaneous measurements of soil moisture content profiles, mean meteorological …

Quantifying Simultaneous Fluxes Of Ozone, Carbon Dioxide And Water Vapor Above A Subalpine Forest Ecosystem
Zeller, K., Nikolov, N.

Assessing the long-term exchange of trace gases and energy between terrestrial ecosystems and the atmosphere is an important priority of the current climate change research. In this regard, it is particularly significant to provide valid data on simultaneous fluxes of carbon, …

Effects Of Climate Variability On The Carbon Dioxide, Water, And Sensible Heat Fluxes Above A Ponderosa Pine Plantation In The Sierra Nevada (CA)
Goldstein, A., Hultman, N., Fracheboud, J., Bauer, M., Panek, J., Xu, M., Qi, Y., Guenther, A., Baugh, W.

Fluxes of CO2, water vapor, and sensible heat were measured by the eddy covariance method above a young ponderosa pine plantation in the Sierra Nevada Mountains (CA) over two growing seasons (1 June–10 September 1997 and 1 May–30 October 1998). The Mediterranean-type climate of California is characterized by a protracted …

Ozone Deposition To A Ponderosa Pine Plantation In The Sierra Nevada Mountains (CA): A Comparison Of Two Different Climatic Years
Bauer, M. R., Hultman, N. E., Panek, J. A., Goldstein, A. H.

Ponderosa pine is one of the most sensitive species to ozone and a dominant species in the Sierra Nevada Mountains. To assess the factors controlling ozone deposition to the forest and to study the forest …

Correcting Eddy-Covariance Flux Underestimates Over A Grassland
Twine, T., Kustas, W., Norman, J., Cook, D., Houser, P., Meyers, T., Prueger, J., Starks, P., Wesely, M.

Independent measurements of the major energy balance flux components are not often consistent with the principle of conservation of energy. This is referred to as a lack of closure of the surface energy balance. Most results in the literature have shown the sum of sensible …

Seasonal And Interannual Variability Of Energy Fluxes Over A Broadleaved Temperate Deciduous Forest In North America
Wilson, K. B., Baldocchi, D. D.

The components of the surface energy balance were measured for 3 years over a broadleaved deciduous forest using the eddy covariance technique. Within years, the magnitude and distribution of fluxes was controlled by seasonal changes in solar radiation, drought, as well as leaf emergence and senescence. Evapotranspiration increased …

Quantifying Biogenic And Anthropogenic Contributions To Acetone Mixing Ratios In A Rural Environment
Goldstein, A. H., Schade, G. W.

Acetone was one of the most abundant volatile organic compounds (VOCs) observed in the Sierra Nevada Mountains (California, USA). Mixing ratios were measured hourly above a ponderosa pine plantation using an automated in situ dual-channel GC-FID system throughout July 1997, …

Surface Heat Flux Estimation With Wind-Profiler/RASS And Radiosonde Observations
Jacobs, J. M., Coulter, R. L., Brutsaert, W.

A bulk ABL similarity approach was used to make regional estimates of the sensible heat flux by combining surface temperature measurements with mixed layer temperature and wind speed profiles. The mixed layer profiles were measured by a 915 MHz Profiler/Radio Acoustic Sounding …

Long-Term Impacts Of Agriculture On Soil Carbon And Nitrogen In New England Forests
Compton, J. E., Boone, R. D.

Abandonment and reforestation of agricultural lands has been a major influence on the landscape of eastern North America. Cultivation and soil amendments can dramatically alter soil nutrient pools and cycling, yet few studies have examined the long-term (>50 yr) influence of pasturing and cultivation on soil processes in the forests …
