Mapping and monitoring of leaf area index (LAI) is important for spatially distributed modeling of vegetation productivity, evapotranspiration, and surface energy balance. Global LAI surfaces will be an early product of the MODIS Land Science Team, and the requirements for …

Vourlitis, G. L., Oechel, W. C.
Eddy covariance was used to measure the net CO2 exchange and energy balance of a moist-tussock tundra ecosystem at Happy Valley, Alaska (69°08.54′ N, 148°50.47′ W), during the 1994–1995 growing seasons (June–August). The system operated for 75–95% of the time, and energy balance closure was within 5%, indicating …

Gu, L., Shugart, H. H., Fuentes, J. D., Black, T., Shewchuk, S. R.
An integrated model of canopy micrometeorology and exchanges of mass and energy was developed and tested for a two-story boreal forest. Roles of different elements of this forest ecosystem in determining net ecosystem exchanges (NEEs) of sensible heat, water vapor and CO2 were analyzed by using the model. In this model, …

Moncrieff, J. B., Fang, C.
In this paper, the one-dimensional, process-based soil CO2 model (PATCIS) described in Part 1 is parameterized and validated with field data collected in a mature slash pine plantation in Florida. The results of a model sensitivity analysis show that CO2 …

Rayment, M. B., Jarvis, P. G.
Four large cuvettes were used to measure whole-branch CO2 and H2O vapour exchange at the Boreal Ecosystem-Atmosphere Study, Southern Study Area, Old Black Spruce site. Measurements started before the spring thaw and continued until after the winter freeze-up. Daytime photosynthesis, nighttime respiration, transpiration …

Fuentes, J. D., Wang, D.
Measurements of isoprene concentration and flux were made at a mixed deciduous forest in southern Canada during 1995 to characterize diel and seasonal emissions and thus deduce annual inventories. Isoprene …

Lamanna, M. S., Goldstein, A. H.
A fully automated gas chromatograph-flame ionization detector system was designed and built to measure ambient concentrations of C2-C10 volatile organic compounds, including many oxygenated compounds, without using liquid cryogen. It was deployed at Blodgett Forest Research Station in Georgetown, California, …

Reich, P. B., Turner, D. P., Bolstad, P.
Substantial research seeks to improve estimates of ecosystem processes and fluxes at a range of scales, notably from the stand scale (<1 km2) using ecosystem physiology and eddy covariance techniques, to the landscape (∼102 km2) and …

Amiro, B., MacPherson, J. I., Desjardins, R. L.
Fire is the dominant stand-replacing agent in the Canadian boreal forest, but few quantitative measurements are available on the micrometeorological effects of fire. Airborne flux measurements during the BOREAS experiment were referenced to age of burn along a 500-km transect …

Gu, L., Fuentes, J. D., Shugart, H. H., Staebler, R. M., Black, T. A.
We analyzed half-hourly tower-based flux measurements of carbon dioxide (CO2) from a boreal aspen forest and a temperate mixed deciduous forest in Canada to examine the influences of clouds on forest carbon uptake. We showed that the presence of clouds consistently and significantly increased the net ecosystem exchanges …
