Influence Of Clouds And Diffuse Radiation On Ecosystem-Atmosphere Co2and Co18o Exchanges
Still, C. J., Riley, W. J., Biraud, S. C., Noone, D. C., Buenning, N. H., Randerson, J. T., Torn, M. S., Welker, J., White, J. W., Vachon, R., Farquhar, G. D., Berry, J. A.

This study evaluates the potential impact of clouds on ecosystem CO2 and CO2 isotope fluxes (“isofluxes”) in two contrasting ecosystems (a broadleaf deciduous forest and a C4 grassland) in a region for which cloud cover, meteorological, and isotope data are available for driving the isotope‐enabled land surface model (ISOLSM). …

Regional Co2and Latent Heat Surface Fluxes In The Southern Great Plains: Measurements, Modeling, And Scaling
Riley, W. J., Biraud, S. C., Torn, M. S., Fischer, M. L., Billesbach, D. P., Berry, J. A.

Characterizing net ecosystem exchanges (NEE) of CO2 and sensible and latent heat fluxes in heterogeneous landscapes is difficult, yet critical given expected changes in climate and land use. We report here a measurement and modeling study designed to improve our understanding of surface to atmosphere gas exchanges under very heterogeneous …

The Ecohydrologic Significance Of Hydraulic Redistribution In A Semiarid Savanna
Scott, R. L., Cable, W. L., Hultine, K. R.

Recent studies have illuminated the process of hydraulic redistribution, defined as the translocation of soil moisture via plant root systems, but the long-term ecohydrologic significance of this process is poorly understood. We investigated hydraulic redistribution (HR) by Prosopis velutina Woot. (velvet mesquite) in an …

Spring Warming And Carbon Dioxide Exchange Over Low Arctic Tundra In Central Canada
Lafleur, P.M., Humphreys, E.R.

Tundra-atmosphere exchanges of carbon dioxide (CO2) and water vapour were measured near Daring Lake, Northwest Territories in the Canadian Low Arctic for 3 years, 2004–2006. The measurement period spanned late-winter until the end of the growing period. Mean temperatures during the measurement period varied from about …

Effect Of Remote Sensing Spatial Resolution On Interpreting Tower-Based Flux Observations
Li, F., Kustas, W. P., Anderson, M. C., Prueger, J. H., Scott, R. L.

Validation comparisons between satellite-based surface energy balance models and tower-based flux measurements over heterogeneous landscapes can be strongly influenced by the spatial resolution of the remote sensing inputs. In this paper, a two-source energy balance model developed to use thermal and visible /near-infrared remotely …

Thinning Reduces Soil Carbon Dioxide But Not Methane Flux From Southwestern Usa Ponderosa Pine Forests
Sullivan, B., Kolb, T., Hart, S., Kaye, J., Dore, S., Montes-Helu, M.

Forest soils are important components of the global carbon cycle because they both store and release carbon. Carbon dioxide is released from soil to the atmosphere as a result of plant root and microbial respiration. Additionally, soils in dry forests are often sinks of methane from the atmosphere. Both carbon dioxide and methane …
