Forest Thinning And Soil Respiration In A Ponderosa Pine Plantation In The Sierra Nevada
Tang, J., Qi, Y., Xu, M., Misson, L., Goldstein, A. H.

Soil respiration is controlled by soil temperature, soil water, fine roots, microbial activity, and soil physical and chemical properties. Forest thinning changes soil temperature, soil water content, and root density and activity, and thus changes soil respiration. We measured soil respiration monthly and soil temperature and volumetric …

Continuous Measurements Of Soil Respiration With And Without Roots In A Ponderosa Pine Plantation In The Sierra Nevada Mountains
Tang, J., Misson, L., Gershenson, A., Cheng, W., Goldstein, A. H.

Continuous measurements of soil respiration and its components help us understand diurnal and seasonal variations in soil respiration and its mechanism. We continuously measured CO2 concentration at various depths in the soil and calculated surface CO2efflux …

Observations Of Total Alkyl Nitrates Within The Sacramento Urban Plume
Cleary, P. A., Murphy, J. G., Day, P. J. Wooldridge, D. A., Millet, D. B., McKay, M., Goldstein, A. H., Cohen, R. C.

During the summer of 2001, NO2, total peroxy nitrates (ΣPNs), total alkyl nitrates (ΣANs), HNO3, volatile organic compounds (VOC), CO2, O3, and meteorological variables were measured at Granite Bay, CA. The diurnal variation in ΣPNs, ΣANs and HNO3 were all strongly correlated …

The Influence Of Light Environment On Photosynthesis And Basal Methylbutenol Emission From Pinus Ponderosa
Gray, D. W., Goldstein, A. H., Lerdau, M. T.

Methylbutenol is a 5-carbon alcohol that is produced and emitted by several species of pine in western North America, and may have important impacts on the tropospheric chemistry …

Influences Of Recovery From Clear-Cut, Climate Variability, And Thinning On The Carbon Balance Of A Young Ponderosa Pine Plantation
Misson, L., Tang, J., Xu, M., McKay, M., Goldstein, A.

From 1999 to 2002, the variations in carbon flux due to management practices (shrub removal, thinning) and climate variability were observed in a young ponderosa pine forest originated from clear-cutting and plantation in 1990. These measurements were done at the Blodgett Forest Ameriflux site located in the Sierra Nevada Mountains …

Atmospheric Aerosol Light Scattering And Surface Wetness Influence The Diurnal Pattern Of Net Ecosystem Exchange In A Semi-Arid Ponderosa Pine Plantation
Misson, L., Lunden, M., McKay, M., Goldstein, A. H.

The diurnal variation of net ecosystem exchange (NEE) showed an unusual pattern at the Blodgett Forest Ameriflux site, with late afternoon NEE lower than early morning (indicating more uptake), while air temperature and atmospheric vapor pressure deficit were much higher. …

Observations Of Oxidation Products Above A Forest Imply Biogenic Emissions Of Very Reactive Compounds
Holzinger, R., Lee, A., Paw, K. T., Goldstein, A. H.

Vertical gradients of mixing ratios of volatile organic compounds have been measured in a Ponderosa pine forest in Central California (38.90° N, 120.63° W, 1315m). These measurements reveal large quantities of previously unreported oxidation products of short lived biogenic precursors. The emission of biogenic precursors must be …

Evapotranspiration Models Compared On A Sierra Nevada Forest Ecosystem
Fisher, J. B., DeBiase, T. A., Qi, Y., Xu, M., Goldstein, A. H.

Evapotranspiration, a major component in terrestrial water balance and net primary productivity models, is difficult to measure and predict. This study compared five models of potential evapotranspiration (PET) applied to a ponderosa pine forest ecosystem at an AmeriFlux …

Associations Between Carbon Isotope Ratios Of Ecosystem Respiration, Water Availability And Canopy Conductance
McDowell, N. G., Bowling, D. R., Schauer, A., Irvine, J., Bond, B. J., Law, B. E., Ehleringer, J. R.

We tested the hypothesis that the stable carbon isotope signature of ecosystem respiration (δ13CR) was regulated by canopy conductance (Gc) using weekly Keeling plots (n=51) from a semiarid old-growth ponderosa pine (Pinus ponderosa) forest in Oregon, USA. For …

A Comparison Of Three Approaches To Modeling Leaf Gas Exchange In Annually Drought-Stressed Ponderosa Pine Forests
Misson, L., Panek, J. A., Goldstein, A. H.
We tested, compared and modified three models of stomatal conductance at the leaf level in a forest ecosystem where drought stress is a major factor controlling forest productivity. The models were tested against 2 years (1999 and 2000) of leaf-level measurements on ponderosa pine (Pinus ponderosaDougl. …
