Warm spring reduced carbon cycle impact of the 2012 US summer drought
Wolf, S., Keenan, T.F., Fisher, J.B., Baldocchi, D.D., Desai, A.R., Richardson, A.D., Scott, R.L., Law, B.E., Litvak, M.E., Brunsell, N.A., Peters, W., van der Laan-Luijkx, I.T.

The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced exceptionally warm temperatures and the most severe drought since the Dust Bowl era of the 1930s, resulting …

Bayesian Optimization Of The Community Land Model Simulated Biosphere–Atmosphere Exchange Using Co2observations From A Dense Tower Network And Aircraft Campaigns Over Oregon
Schmidt, A., Law, B. E., Göckede, M., Hanson, C., Yang, Z., Conley, S.

The vast forests and natural areas of the Pacific Northwest compose one of the most productive ecosystems in the Northern Hemisphere. The heterogeneous landscape of Oregon poses a particular challenge to ecosystem models. This study presents a framework using a scaling factor Bayesian inversion to improve the modeled atmosphere–biosphere …

Five Years Of Carbon Fluxes And Inherent Water-Use Efficiency At Two Semi-Arid Pine Forests With Different Disturbance Histories
Vickers, D., Thomas, C., Pettijohn, C., Martin, J.G., Law, B.E.

Five years of eddy-covariance and other measurements at a mature ponderosa pine forest and a nearby young plantation are used to contrast the carbon fluxes for long-term averages, seasonal patterns, diel patterns and interannual variability, and to examine …

Nocturnal Subcanopy Flow Regimes And Missing Carbon Dioxide
Vickers, D., Irvine, J., Martin, J. G., Law, B. E.

Two distinct nocturnal subcanopy flow regimes are observed beneath a tall (16 m) open pine forest canopy. The first is characterized by weaker mixing, stronger stability, westerly downslope flow decoupled from the flow above the canopy and much smaller than expected …

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 …

Seasonal Hydrology Explains Interannual And Seasonal Variation In Carbon And Water Exchange In A Semiarid Mature Ponderosa Pine Forest In Central Oregon
Thomas, C. K., Law, B. E., Irvine, J., Martin, J. G., Pettijohn, J. C., Davis, K. J.

We analyzed 7 years (2002–2008) of micrometeorological and concurrent biological observations of carbon and water fluxes at a mature ponderosa pine forest in central Oregon in a semiarid climate. We sought to evaluate the extent that gross primary productivity, net ecosystem exchange, ecosystem respiration, net primary productivity, …

Random And Systematic CO2 Flux Sampling Errors For Tower Measurements Over Forests In The Convective Boundary Layer
Vickers, D., Thomas, C., Law, B. E.

The perturbation timescale-dependences of the CO2 flux and the random flux sampling error are evaluated from eddy-covariance tower observations in the mid-day convective boundary layer over mid-latitude conifer forests. The perturbation timescale is the timescale used in the standard Reynolds decomposition to …

Self-Correlation Between Assimilation And Respiration Resulting From Flux Partitioning Of Eddy-Covariance CO2 Fluxes
Vickers, D., Thomas, C. K., Martin, J. G., Law, B.

Self-correlation between estimates of assimilation and respiration of carbon is a consequence of the flux partitioning of eddy-covariance measurements, where the assimilation is computed as the difference between the measured net carbon dioxide flux (NEE) and an …
