Interannual Variation Of Soil Respiration In Two New England Forests
Savage, K. E., Davidson, E. A.

Soil respiration is an important component of the annual carbon balance of forests, but few studies have addressed interannual variation in soil respiration. The objectives of this study were to investigate the seasonal and interannual variation in soil respiration, temperature, precipitation, and soil water content in two New England …

Influence Of Biotic Exchange And Combustion Sources On Atmospheric CO2 Concentrations In New England From Observations At A Forest Flux Tower
Potosnak, M. J., Wofsy, S. C., Denning, A. S., Conway, T. J., Munger, J. W., Barnes, D. H.

Hourly data for concentrations and fluxes of CO2 at 30 m in Harvard Forest (Petersham, Massachusetts) are analyzed using linear modeling to obtain regionally representative CO2 concentrations …

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

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 …

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 …

Measurements Of Carbon Sequestration By Long-Term Eddy Covariance: Methods And A Critical Evaluation Of Accuracy
Goulden, M. L., Munger, J. W., Fan, S., Daube, B. C., Wofsy, S. C.

The turbulent exchanges of CO2 and water vapour between an aggrading deciduous forest in the north-eastern United States (Harvard Forest) and the atmosphere were measured from 1990 to 1994 using the eddy covariance technique. We present a detailed description of the methods used and a rigorous evaluation of the precision …

Seasonal Variation In Radiative And Turbulent Exchange At A Deciduous Forest In Central Massachusetts
Moore, K. E., Fitzjarrald, D. R., Sakai, R. K., Goulden, M. L., Munger, J. W., Wofsy, S. C.

Temperate deciduous forests exhibit dramatic seasonal changes in surface exchange properties following on the seasonal changes in leaf area index. Nearly continuous measurements of turbulent and radiative fluxes above and below the canopy of a red oak forest in central Massachusetts have been ongoing since the summer of 1991. Several …
