Evidence Of Increased Net Ecosystem Productivity Associated With A Longer Vegetated Season In A Deciduous Forest In South-Central Indiana, Usa
DRAGONI, D., SCHMID, H. P., WAYSON, C. A., POTTER, H., GRIMMOND, C. S., RANDOLPH, J. C.

Observations of net ecosystem exchange (NEE) of carbon and its biophysical drivers have been collected at the AmeriFlux site in the Morgan-Monroe State Forest (MMSF) in Indiana, USA since 1998. Thus, this is one of the few deciduous forest sites in the world, where a decadal analysis on net ecosystem productivity (NEP) trends is …

Predicting The Onset Of Net Carbon Uptake By Deciduous Forests With Soil Temperature And Climate Data: A Synthesis Of FLUXNET Data
Baldocchi, D. D., Black, T. A., Curtis, P. S., Falge, E., Fuentes, J. D., Granier, A., Gu, L., Knohl, A., Lee, X., Pilegaard, K., Schmid, H. P., Valentini, R., Wilson, K., Wofsy, S., Xu, L., Yamamoto, S.

We tested the hypothesis that the date of the onset of net carbon uptake by temperate deciduous forest canopies corresponds with the time when the mean daily soil temperature equals the mean annual air temperature. The hypothesis was tested using over 30 …

Midday Values Of Gross CO2 Flux And Light Use Efficiency During Satellite Overpasses Can Be Used To Directly Estimate Eight-Day Mean Flux
Sims, D. A., Rahman, A. F., Cordova, V. D., Baldocchi, D. D., Flanagan, L. B., Goldstein, A. H., Hollinger, D. Y., Misson, L., Monson, R. K., Schmid, H. P., Wofsy, S. C., Xu, L.

Most satellites provide, at best, a single daily snapshot of vegetation and, at worst, these snapshots may be separated by periods of many days when the ground was obscured by cloud cover. Since vegetation carbon exchange can be very dynamic on diurnal and day-to-day timescales, the limited temporal resolution of satellite data is …

Heat Storage And Energy Balance Fluxes For A Temperate Deciduous Forest
Oliphant, A., Grimmond, C., Zutter, H., Schmid, H., Su, H., Scott, S., Offerle, B., Randolph, J., Ehman, J.

Hourly observations of forest-atmosphere energy balance components are presented for the Morgan-Monroe State Forest, south-central Indiana, USA for the period March 1998 to December 2001, with particular emphasis on the storage heat flux (ΔQS). The sub-components of ΔQS showed strong diurnal …

Potential Of MODIS Ocean Bands For Estimating CO2flux From Terrestrial Vegetation: A Novel Approach
Rahman, A. F., Cordova, V. D., Gamon, J. A., Schmid, H. P., Sims, D. A.

A physiologically-driven spectral index using two ocean-color bands of MODIS satellite sensor showed great potential to track seasonally changing photosynthetic light use efficiency (LUE) and stress-induced reduction in net primary productivity (NPP) of terrestrial vegetation. Based on these findings, we developed a simple “continuous …

An Initial Intercomparison Of Micrometeorological And Ecological Inventory Estimates Of Carbon Exchange In A Mid-Latitude Deciduous Forest
Ehman, J. L., Schmid, H. P., Grimmond, C. S., Randolph, J. C., Hanson, P. J., Wayson, C. A., Cropley, F. D.

The role of mid-latitude forests in the sequestration of carbon (C) is of interest to an increasing number of scientists and policy-makers alike. Net CO2 exchange …

Biometric And Eddy-Covariance Based Estimates Of Annual Carbon Storage In Five Eastern North American Deciduous Forests
Curtis, P. S., Hanson, P. J., Bolstad, P., Barford, C., Randolph, J., Schmid, H., Wilson, K. B.

Quantifying net carbon (C) storage by forests is a necessary step in the validation of carbon sequestration estimates and in assessing the possible role of these ecosystems in offsetting fossil fuel emissions. In eastern North America, five sites were established in deciduous …

Belowground Carbon Allocation In Forests Estimated From Litterfall And IRGA-Based Soil Respiration Measurements
Davidson, E., Savage, K., Bolstad, P., Clark, D., Curtis, P., Ellsworth, D., Hanson, P., Law, B., Luo, Y., Pregitzer, K., Randolph, J., Zak, D.

Allocation of C to belowground plant structures is one of the most important, yet least well quantified fluxes of C in terrestrial ecosystems. In a literature review of mature forests worldwide, Raich …

FLUXNET: A New Tool To Study The Temporal And Spatial Variability Of Ecosystem–Scale Carbon Dioxide, Water Vapor, And Energy Flux Densities
Baldocchi, D., Falge, E., Gu, L., Olson, R., Hollinger, D., Running, S., Anthoni, P., Bernhofer, C., Davis, K., Evans, R., Fuentes, J., Goldstein, A., Katul, G., Law, B., Lee, X., Malhi, Y., Meyers, T., Munger, W., Oechel, W., Paw, K. T., Pilegaard, K., Schmid, H. P., Valentini, R., Verma, S., Vesala, T., Wilson, K., Wofsy, S.

FLUXNET is a global network of micrometeorological flux measurement sites that measure the exchanges of carbon dioxide, water vapor, and energy between the biosphere and atmosphere. At present over 140 sites are operating on a long–term and continuous basis. Vegetation under study includes temperate conifer and broadleaved (deciduous …
