We present the annual patterns of net ecosystem-atmosphere exchange (NEE) of CO2 and H2O observed from a 447 m tall tower sited within a mixed forest in northern …

Field-chamber measurements of soil respiration from 17 different forest and shrubland sites in Europe and North America were summarized and analyzed with the goal to develop a model describing seasonal, interannual and spatial variability of soil respiration as affected by water availability, temperature, and site properties. The …

Sparks, J. P., Roberts, J. M., Monson, R. K.
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 …

Lafleur, P. M., Roulet, N. T., Bubier, J. L., Frolking, S., Moore, T. R.
Eddy covariance measurements of net ecosystem carbon dioxide (CO2) exchange (NEE) were taken at an ombrotrophic bog near Ottawa, Canada from 1 June 1998 to 31 May 2002. Temperatures during this period were above normal except for 2000 and precipitation was near normal in 1998 and 1999, above normal in 2000, and well below …

Hymus, G. J., Johnson, D. P., Dore, S., Anderson, H. P., Ross Hinkle, C., Drake, B. G.
We report the results of a 2-year study of effects of the elevated (current ambient plus 350 μmol CO2 mol−1) atmospheric CO2 concentration (Ca) on net ecosystem CO2 exchange (NEE) of a scrub–oak ecosystem. The measurements were made in open-top chambers …

Song, J., Wesely, M.
Evaluation of models of air–surface exchange is facilitated by an accurate match of areas simulated with those seen by micrometeorological flux measurements. Here, spatial variations in fluxes estimated with the parameterized subgrid-scale surface (PASS) flux model were compared to flux variations seen aboard aircraft above the …
