Diurnal And Annual Exchanges Of Mass And Energy Between An Aspen-Hazelnut Forest And The Atmosphere: Testing The Mathematical Model Ecosys With Data From The BOREAS Experiment
Grant, R. F., Black, T. A., den Hartog, G., Berry, J. A., Neumann, H. H., Blanken, P. D., Yang, P. C., Russell, C., Nalder, I. A.

There is much uncertainty about the net carbon (C) exchange of boreal forest ecosystems, although this exchange may be an important part of global C dynamics. To resolve this uncertainty, net C exchange has …

The Carbon Balance Of Tropical, Temperate And Boreal Forests
Malhi, Y., Baldocchi, D. D., Jarvis, P. G.

Forest biomes are major reserves for terrestrial carbon, and major components of global primary productivity. The carbon balance of forests is determined by a number of component …

Dynamics Of Isotopic Exchange Of Carbon Dioxide In A Tennessee Deciduous Forest
Bowling, D. R., Baldocchi, D. D., Monson, R. K.

The combination of isotopic measurements and micrometeorological flux measurements is a powerful new approach that will likely lead to new insight into the dynamics of CO2 exchange between terrestrial …

On The Seasonality Of Isoprene Emissions From A Mixed Temperate Forest
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 …

The Use Of Relaxed Eddy Accumulation To Measure Biosphere-Atmosphere Exchange Of Isoprene And Other Biological Trace Gases
Bowling, D. R., Turnipseed, A. A., Delany, A. C., Baldocchi, D. D., Greenberg, J. P., Monson, R. K.

The micrometeorological flux measurement technique known as relaxed eddy accumulation (REA) holds promise as a powerful new tool for ecologists. The more popular eddy covariance (eddy correlation) technique requires the use of sensors that can respond at fast rates (10 Hz), and these are unavailable for many ecologically relevant …

On Using Eco-Physiological, Micrometeorological And Biogeochemical Theory To Evaluate Carbon Dioxide, Water Vapor And Trace Gas Fluxes Over Vegetation: A Perspective
Baldocchi, D., Meyers, T.

How eco-physiological, biogeochemical and micrometeorological theory can be used to compute biosphere–atmosphere, trace gas exchange rates is discussed within the framework of a process model. The accuracy of the theory is tested by comparing computations of mass and energy flux densities (water vapor, sensible heat, CO2

Seasonal Course Of Isoprene Emissions From A Midlatitude Deciduous Forest
Goldstein, A. H., Goulden, M. L., Munger, J. W., Wofsy, S. C., Geron, C. D.

Continuous measurements of whole canopy isoprene emissions over an entire growing season are reported from Harvard Forest (42°32′N, 72°11′W). Emissions were calculated from the ratio of observed CO2

Relationship Between Ecosystem Productivity And Photosynthetically Active Radiation For Northern Peatlands
Frolking, S. E., Bubier, J. L., Moore, T. R., Ball, T., Bellisario, L. M., Bhardwaj, A., Carroll, P., Crill, P. M., Lafleur, P. M., McCaughey, J. H., Roulet, N. T., Suyker, A. E., Verma, S. B., Waddington, J. M., Whiting, G. J.

We analyzed the relationship between net ecosystem exchange of carbon dioxide (NEE) and irradiance (as photosynthetic photon flux density or PPFD), using published and unpublished data that have been collected during midgrowing season for carbon balance studies at seven peatlands in North America and Europe. NEE measurements included …
