Sun, J., Oncley, S. P., Burns, S. P., Stephens, B. B., Lenschow, D. H., Campos, T., Watt, A. S., Monson, R. K., Moore, D. J., Hu, J., Tschudi, M., Schimel, D. S., Aulenbach, S., Sacks, W. J., De Wekker, S. F., Lai, C., Lamb, B., Allwine, E., Coons, T., Ojima, D., Ellsworth, P. Z., Sternberg, L. S., Zhong, S., Clements, C., Anderson, D. E.

A significant fraction of Earth consists of mountainous terrain. However, the question of how to monitor the surface–atmosphere carbon exchange over complex terrain has not been fully explored. This article reports on studies by a team of investigators from U.S. universities and research institutes who carried out a multiscale …

Biometric And Eddy-Covariance Based Estimates Of Carbon Fluxes In An Age-Sequence Of Temperate Pine Forests
Peichl, M., Brodeur, J. J., Khomik, M., Arain, M. A.

We present four years (2005–2008) of biometric (B) and eddy-covariance (EC) measurements of carbon (C) fluxes to constrain estimates of gross primary production (GPP), net primary production (NPP), ecosystem respiration (RE) and net ecosystem production (NEP) in an age-sequence (6-, 19-, 34-, and 69-years-old in 2008) of pine forests …

Plant-Soil Interactions And Acclimation To Temperature Of Microbial-Mediated Soil Respiration May Affect Predictions Of Soil CO2 Efflux
Curiel Yuste, J., Ma, S., Baldocchi, D. D.

It is well known that microbial-mediated soil respiration, the major source of CO2 from terrestrial ecosystems, is sensitive to temperature. Here, we hypothesize that some mechanisms, such as acclimation of microbial respiration to temperature and/or regulation by plant fresh C inputs of the temperature sensitivity of …

Uncertainty Estimates For 1-H Averaged Turbulence Fluxes Of Carbon Dioxide, Latent Heat And Sensible Heat
Vickers, D., Göckede, M., Law, B.

A new observational approach is presented to approximate the uncertainty (scatter or error variance) in 1-h averaged turbulence fluxes …

Ecosystem Carbon Dioxide Fluxes After Disturbance In Forests Of North America
Amiro, B.D., Barr, A.G., Barr, J.G., Black, T.A., Bracho, R., Brown, M., Chen, J., Clark, K.L., Davis, K.J., Desai, A.R., Dore, S., Engel, V., Fuentes, J.D., Goldstein, A.H., Goulden, M.L., Kolb, T.E., Lavigne, M.B., Law, B.E., Margolis, H.A., Martin, T., McCaughey, J.H., Misson, L., Montes-Helu, M., Noormets, A., Randerson, J.T., Starr, G., Xiao, J.

Disturbances are important for renewal of North American forests. Here we summarize more than 180 site years of eddy covariance measurements of carbon dioxide flux made at forest chronosequences in North America. The disturbances included stand-replacing fire (Alaska, Arizona, Manitoba, and Saskatchewan) and harvest (British Columbia, …

The Effect Of Permafrost Thaw On Old Carbon Release And Net Carbon Exchange From Tundra
Schuur, E. A., Vogel, J. G., Crummer, K. G., Lee, H., Sickman, J. O., Osterkamp, T. E.

Permafrost soils in boreal and Arctic ecosystems store almost twice as much carbon1, 2 as is currently present in the atmosphere

Controls Over Ozone Deposition To A High Elevation Subalpine Forest
Turnipseed, A. A., Burns, S. P., Moore, D. J., Hu, J., Guenther, A. B., Monson, R. K.

Ecosystem level ozone (O3) fluxes during four different years were examined at a subalpine forest site in the Colorado Rocky Mountains. The local mountain–valley wind system and the proximity of the Denver Metropolitan area leads to high summertime ozone episodes on many afternoons. The timing between these episodes and the ecosystem …

Methane Fluxes During The Initiation Of A Large-Scale Water Table Manipulation Experiment In The Alaskan Arctic Tundra
Zona, D., Oechel, W. C., Kochendorfer, J., Paw U, K. T., Salyuk, A. N., Olivas, P. C., Oberbauer, S. F., Lipson, D. A.

Much of the 191.8 Pg C in the upper 1 m of Arctic soil of Arctic soil organic mater is, or is at risk of, being released to the atmosphere as CO2 and/or CH4. Global warming will further alter the rate of emission of these gases to the atmosphere. Here we quantify the effect of major environmental variables affected …

Effects Of Seasonal Drought On Net Carbon Dioxide Exchange From A Woody-Plant-Encroached Semiarid Grassland
Scott, R.L., Jenerette, G.D., Potts, D.L., Huxman, T.E.

Annual precipitation in the central and southern warm-desert region of North America is distributed climatologically between summer and winter periods with two prominent dry periods between them. We used energy and carbon dioxide (CO2) fluxes from eddy covariance along with standard meteorological and soil moisture measurements …
