Turnipseed, A., Blanken, P., Anderson, D., Monson, R.
Components of the energy budget were measured above a subalpine coniferous forest over two complete annual cycles. Sensible and latent heat fluxes were measured by eddy covariance. Bowen ratios ranged from 0.7 to 2.5 in the summer (June–September) depending upon the availability of soil water, but were considerably higher (∼3–6) …

Drewitt, G., Black, T., Nesic, Z., Humphreys, E., Jork, E., Swanson, R., Ethier, G., Griffis, T., Morgenstern, K.
CO2 exchange was measured on the forest floor of a coastal temperate Douglas-fir forest located near Campbell River, British Columbia, Canada. Continuous measurements were obtained at six locations using an automated chamber system between April and December, 2000. Fluxes were measured every half hour by circulating chamber …

Langley, J. A., Drake, B. G., Hungate, B. A.
Portions of a regenerating scrub oak ecosystem were enclosed in open-top chambers and exposed to elevated CO2. The distinct 13C signal of the supplemental CO2 was used to trace the rate of C integration into various ecosystem …

Frolking, S., Roulet, N. T., Moore, T. R., Lafleur, P. M., Bubier, J. L., Crill, P. M.
Northern peatlands contain enormous quantities of organic carbon within a few meters of the atmosphere and play a significant role in the planetary carbon balance. We have developed a new, process-oriented model of the contemporary carbon balance of northern peatlands, the Peatland Carbon Simulator (PCARS). Components of PCARS are …

Lai, C., Katul, G., Butnor, J., Ellsworth, D., Oren, R.
One of the main challenges to quantifying ecosystem carbon budgets is properly quantifying the magnitude of night-time ecosystem respiration. Inverse Lagrangian dispersion …

Scurlock, J. M., Johnson, K., Olson, R. J.
To address the need for a high quality data set based upon field observations suitable for parameterization, calibration, and validation of terrestrial biosphere models, we have developed a comprehensive global database on net primary productivity (NPP). We have compiled field measurements of biomass and associated environmental …

Flanagan, L. B., Wever, L. A., Carlson, P. J.
Net ecosystem carbon dioxide (CO2) exchange (NEE) was measured in a northern temperate grassland near Lethbridge, Alberta, Canada for three growing seasons using the eddy covariance technique. The study objectives were to document how NEE and its major component processes—gross photosynthesis (GPP) and total ecosystem …
