Energy Partitioning Between Latent And Sensible Heat Flux During The Warm Season At FLUXNET Sites
Wilson, K. B., Baldocchi, D. D., Aubinet, M., Berbigier, P., Bernhofer, C., Dolman, H., Falge, E., Field, C., Goldstein, A., Granier, A., Grelle, A., Halldor, T., Hollinger, D., Katul, G., Law, B. E., Lindroth, A., Meyers, T., Moncrieff, J., Monson, R., Oechel, W., Tenhunen, J., Valentini, R., Verma, S., Vesala, T., Wofsy, S.

The warm season (mid-June through late August) partitioning between sensible (H) and latent (LE) heat flux, or the Bowen ratio (β = H/LE), was investigated at 27 sites over 66 site years within the international network of eddy covariance sites (FLUXNET). Variability in β across ecosystems and …

Observational Constraints On The Contribution Of Isoprene Oxidation To Ozone Production On The Western Slope Of The Sierra Nevada, California
Dreyfus, G. B., Schade, G. W., Goldstein, A. H.

Observations of isoprene and its oxidation products methacrolein (MACR) and methyl vinyl ketone (MVK) are used to quantify the impact of isoprene oxidation on ozone production along the western slope of the Sierra Nevada mountains. Regular daytime up-slope wind flow patterns transport anthropogenic volatile organic compounds (VOC) …

An evaluation of ozone exposure metrics for a seasonally drought-stressed ponderosa pine ecosystem
Panek, J. A., Kurpius, M. R., Goldstein, A. H.

Ozone stress has become an increasingly significant factor in cases of forest decline reported throughout the world. Current metrics to estimate ozone exposure for forest trees are derived from atmospheric concentrations and assume that the forest is physiologically active at all times of the growing season. This may be inaccurate …

Seasonality Of Ecosystem Respiration And Gross Primary Production As Derived From FLUXNET Measurements
Falge, E., Baldocchi, D., Tenhunen, J., Aubinet, M., Bakwin, P., Berbigier, P., Bernhofer, C., Burba, G., Clement, R., Davis, K. J., Elbers, J. A., Goldstein, A.

T., Pilegaard, K., Rannik, Ü., Rebmann, C., Suyker, A., Valentini, R., Wilson, K., Wofsy, S.

Differences in the seasonal pattern of assimilatory and respiratory processes are responsible for divergences in seasonal net carbon exchange among ecosystems. Using FLUXNET data (

Atmospheric Methyl Tertiary Butyl Ether (MTBE) At A Rural Mountain Site In California
Schade, G. W., Dreyfus, G. B., Goldstein, A. H.

Methyl tertiary butyl ether (MTBE) was measured in air samples collected at hourly intervals near Blodgett Forest Research Station on the western slope of the Sierra Nevada, California, in July 1997, October 1998, and June through September 1999. Mixing ratios ranged from below the detection limit (< approximately 0.01 ppbv) to …

Fluxes of oxygenated volatile organic compounds from a ponderosa pine plantatio
Schade,G.W., Goldstein,A.H.

We present the first canopy-scale, continuous, long-term flux measurements of a suite of oxygenated volatile organic compounds (OVOCs). Fluxes were measured above a ponderosa pine plantation, adjacent to the Blodgett Forest Research Station (38°53′42.9″N, 120°37′57.9″W, 1315 m elevation), with a fully automated relaxed …

Response Of Stomatal Conductance To Drought In Ponderosa Pine: Implications For Carbon And Ozone Uptake
Panek, J. A., Goldstein, A. H.
To gain insight into the limitations imposed by a typical Mediterranean-climate summer drought on the uptake of carbon and ozone in the ponderosa pine (Pinus ponderosa Dougl. ex Laws.) ecosystem, we compared diurnal trends in leaf physiology of young trees in a watered and a control plot …

Large Carbon Isotope Fractionation Associated With Oxidation Of Methyl Halides By Methylotrophic Bacteria
Miller, L. G., Kalin, R. M., McCauley, S. E., Hamilton, J. T., Harper, D. B., Millet, D. B., Oremland, R. S., Goldstein, A. H.

The largest biological fractionations of stable carbon isotopes observed in nature occur during production of methane by methanogenic archaea. These fractionations result in substantial (as much as ≈70‰) shifts in δ13C relative to the initial substrate. We …

Ecosystem Respiration In A Young Ponderosa Pine Plantation In The Sierra Nevada Mountains, California
Xu, M., DeBiase, T. A., Qi, Y., Goldstein, A., Liu, Z.
We estimated total ecosystem respiration from a ponderosa pine (Pinus ponderosa Dougl. ex Laws.) plantation in the Sierra Nevada Mountains near Georgetown, California, from June to October, 1998. We apportioned ecosystem respiration among heterotrophic, root, stem and foliage based on relationships …
