Elevated atmospheric carbon dioxide (Ca) usually reduces stomatal conductance, but the effects on plant transpiration in the field are not well understood. Using …

Kurpius, M. R., Goldstein, A. H.
Tropospheric ozone (O3) effectively deposits to forested ecosystems but the fate of O3 within the forest canopy is unresolved. We partitioned total measured ecosystem daytime O3 deposition to a ponderosa pine (Pinus ponderosa) forest into its major loss pathways; stomatal uptake, non-stomatal …

Tang, J., Baldocchi, D. D., Qi, Y., Xu, L.
This paper describes a new method to monitor continuously soil CO2 profiles using small solid-state CO2 sensors buried at different depths of the soil. Based on the measurement of soil CO2 profile and a gaseous diffusivity model, we estimated …

Dore, S., Hymus, G. J., Johnson, D. P., Hinkle, C. R., Valentini, R., Drake, B. G.
Simultaneous measurements of net ecosystem CO2 exchange (NEE) were made in a Florida scrub-oak ecosystem in August 1997 and then every month between April 2000 to …

[1] There is considerable interest in assessing the magnitude of carbon sources and sinks for agricultural lands, grasslands, and forests. In this paper, we propose a novel …

Gray, D. W., Lerdau, M. T., Goldstein, A. H.
Volatile organic compounds emitted by plants have long been recognized as having important influences on tropospheric chemistry, most notably in contributing to the production of tropospheric ozone and aerosols. One such compound, methylbutenol (MBO), was recently identified as a major component of the volatiles emitted by ponderosa …

Ping, J. L., Dobermann, A.
Annual yield maps are spatially fragmented because of random variation caused by crop management as well as measurement errors. Two approaches for creating maps of spatially contiguous yield classes were evaluated at two irrigated sites. In the first approach, prior-classification interpolation (PCI), grid size was increased from …

Amiro, B. D., Ian MacPherson, J., Desjardins, R. L., Chen, J. M., Liu, J.
Recent CO2 flux measurements from towers and aircraft (net ecosystem exchange by eddy covariance) and remote sensing/modeling (net primary productivity—NPP) following fire show that the regenerating boreal forest in western Canada has a low initial flux that …

Johnson, D. W., Hungate, B. A., Dijkstra, P., Hymus, G., Hinkle, C. R., Stiling, P., Drake, B. G.
Elevated carbon dioxide (CO2) caused greater accumulation of carbon (C) and nutrients in both vegetation and O horizons over a 5-yr sampling period in a scrub oak ecosystem in Florida. Elevated CO2 had no effect on any measured soil property except extractable phosphorus (P), which was lower with elevated CO2 …

There is considerable interest in assessing the magnitude of carbon sources and sinks for agricultural lands, grasslands, and forests. In this paper, we propose a novel technique to remotely assess CO2 fluxes in maize using reflectances (ρ) in two spectral channels either in the green around 550 nm or in the red edge …
