How Environmental Conditions Affect Canopy Leaf-Level Photosynthesis In Four Deciduous Tree Species
Bassow, S. L., Bazzaz, F. A.

Simple And Fast Technique To Measure CO2 Profiles In Soil
Fang, C., Moncrieff, J.

We describe a simple method for sampling soil gas at different profile depths and analyzing CO2 concentration in the gas sample. Soil gas samples were taken on the soil surface from each chosen depth through a gas circulation system and analyzed in situ

Intercomparison Among Chamber, Tower, And Aircraft Net CO2 And Energy Fluxes Measured During The Arctic System Science Land-Atmosphere-Ice Interactions (ARCSS-LAII) Flux Study
Oechel, W. C., Vourlitis, G. L., Brooks, S., Crawford, T. L., Dumas, E.

Measurements of net ecosystem CO2 exchange (NEE) and energy balance were made using chamber-, tower-, and aircraft-based measurement techniques in Alaskan arctic tundra ecosystems during the 1994–1995 …

Regional Budgets For Nitrogen Oxides From Continental Sources: Variations Of Rates For Oxidation And Deposition With Season And Distance From Source Regions
Munger, J. W., Fan, S., Bakwin, P. S., Goulden, M. L., Goldstein, A. H., Colman, A. S., Wofsy, S. C.

Measurements of nitrogen deposition and concentrations of NO, NO2, NOy (total oxidized N), and O3have been made at Harvard Forest in central Massachusetts since 1990 …

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 …

Characteristics Of Energy And Water Budgets Over Wet Sedge And Tussock Tundra Ecosystems At North Slope In Alaska
Harazono, Y., Yoshimoto, M., Mano, M., Vourlitis, G. L., Oechel, W. C.

Energy budgets were measured at Arctic tundra ecosystems in Alaska, USA. Measurements were carried out over coastal tundra at Prudhoe Bay in 1994, and at wet sedge, moist and dry tussock tundra around Happy Valley in 1995. Sensible heat flux, H, and latent heat flux, lE, were determined by an eddy correlation technique.

Estimating Clear-Sky Regional Surface Fluxes In The Southern Great Plains Atmospheric Radiation Measurement Site With Ground Measurements And Satellite Observations
Gao, W., Coulter, R. L., Lesht, B. M., Qiu, J., Wesely, M. L.

The authors compared methods for estimating surface fluxes under clear-sky conditions over a large heterogeneous area from a limited number of ground measurements and from satellite observations using data obtained from the southern Great Plains Cloud and …

Intra- And Inter-Specific Variation In Canopy Photosynthesis In A Mixed Deciduous Forest
Bassow, S. L., Bazzaz, F. A.

Within the same forest, photosynthesis can vary greatly among species and within an individual tree. Quantifying the magnitude of variation in leaf-level photosynthesis in a forest canopy will improve our understanding of and ability to model forest carbon cycling. This information requires extensive sampling of photosynthesis in …
