Hui, D., Wan, S., Su, B., Katul, G., Monson, R., Luo, Y.
Missing data is a ubiquitous problem in evaluating long-term experimental measurements, such as those associated with the FluxNet project, due to the equipment failures, system maintenance, power-failure, and lightning strikes among other things. To estimate annual values …

Xu, L., Baldocchi, D. D.
Understanding how environmental variables affect the processes that regulate the carbon flux over grassland is critical for large-scale modeling research, since grasslands comprise almost one-third of the earth’s natural vegetation. To address this issue, fluxes of CO2 (Fc, flux toward the …

Suwa, M., Katul, G. G., Oren, R., Andrews, J., Pippen, J., Mace, A., Schlesinger, W. H.
The effects of elevated atmospheric CO2 (CO2e) on soil respiration were evaluated using inverse models and static chamber measurements collected over 4.5 years in a maturing loblolly pine forest. The chamber measurements of forest floor CO2 efflux showed that the flux enhancement increased …

Howard, E. A., Gower, S. T., Foley, J. A., Kucharik, C. J.
We calculated carbon budgets for a chronosequence of harvested jack pine (Pinus banksiana Lamb.) stands (0-, 5-, 10-, and∼29-year-old) and a∼79-year-old stand …

Griffis, T., Black, T., Gaumont-Guay, D., Drewitt, G., Nesic, Z., Barr, A., Morgenstern, K., Kljun, N.
Continuous automatic chamber and eddy covariance (EC) measurements were made at an old aspen forest (SOA) located at southern boreal treeline in Saskatchewan, Canada to examine the temporal variability in soil (Rs), tree bole (Rb), and ecosystem respiration (RE) during 2001. …

The magnitude of changes in carboxylation capacity in dominant plant species under long-term elevated CO2 exposure (elevated pCa) directly impacts …

Kruijt, B., Elbers, J. A., von Randow, C., Araújo, A. C., Oliveira, P. J., Culf, A., Manzi, A. O., Nobre, A. D., Kabat, P., Moors, E. J.
We analyzed errors and uncertainties in time-integrated eddy correlation data for sites in the Amazon. A well-known source of potential error in eddy correlation is through possible advective losses of CO2emissions during calm nights. There are also questions related to the treatment of low frequencies, non-horizontal …

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 …
