Using data from 28 flux measurement sites, we performed an analysis of the relationship between annual net ecosystem exchange (NEE) and the length of the carbon uptake period …

Eddy covariance measurements of carbon dioxide (CO2) and water vapour fluxes were made from June 2002 to May 2003 over a 65-year-old temperate conifer plantation forest in southern Ontario, Canada. This site is part of a newly initiated long-term tower flux measurement …

The nocturnal drainage flow of air causes significant uncertainty in ecosystem CO2, H2O, and energy budgets determined with the eddy covariance measurement approach. In this study, we examined the magnitude, nature, and dynamics of the nocturnal drainage flow in a subalpine forest ecosystem with complex terrain. …

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 …

Turnipseed, A. A., Anderson, D. E., Burns, S., Blanken, P. D., Monson, R. K.
The location of the Niwot Ridge Ameriflux site within the rocky mountains subjects it to airflows which are common in mountainous terrain. In this study, we examine the effects of some of these mesoscale features on local turbulent flux measurements; most notably, the formation of valley/mountain flows and mountain lee-side …

Future climate change is expected to affect ecosystem-atmosphere CO2 exchange, particularly through the influence of temperature. To date, however, few studies have shown that differences in the response of net ecosystem CO2 exchange (NEE) to temperature among ecosystems can be explained by differences in the …

Turnipseed, A. A., Anderson, D. E., Blanken, P. D., Baugh, W. M., Monson, R. K.
We have studied the effects of local topography and canopy structure on turbulent flux measurements at a site located in mountainous terrain within a subalpine, coniferous forest. Our primary aim was to determine whether the complex terrain of the site affects the accuracy of eddy flux measurements from a practical perspective. We …

We report measurements of the uptake of peroxyacetyl nitrate (PAN) by plant leaves at mixing ratios typical of the continental lower troposphere. PAN uptake rates between 20 and 55 pmol m−2 s−1 were measured in eight plant species at an atmospheric mixing ratio of 250 pptv. Uptake rates in all species were …

Huxman, T. E., Turnipseed, A. A., Sparks, J. P., Harley, P. C., Monson, R. K.
We evaluated the hypothesis that CO2 uptake by a subalpine, coniferous forest is limited by cool temperature during the growing season. Using the eddy covariance approach we conducted observations of net ecosystem CO2 exchange (NEE) across two growing seasons. When pooled for the entire growing season during …

We studied net ecosystem CO2 exchange (NEE) dynamics in a high-elevation, subalpine forest in Colorado, USA, over a two-year period. Annual carbon sequestration for the forest was 6.71 mol C m−2(80.5 g C m−2) for the year between November 1, 1998 and October 31, 1999, and 4.80 mol C m−2(57.6 g C m−2) …
