    • Analytic Webs Support the Synthesis of Ecological Data Sets 

      Ellison, Aaron M.; Osterweil, Leon; Hadley, Julian L.; Wise, Alexander; Boose, Emery Robert; Clarke, Lori; Foster, David Russell; Hanson, Allen; Jensen, David Michael; Kuzeja, Paul; Riseman, Edward; Schultz, Howard (Ecological Society of America, 2006)
      A wide variety of data sets produced by individual investigators are now synthesized to address ecological questions that span a range of spatial and temporal scales. It is important to facilitate such syntheses so that ...

    • Deriving a Light Use Efficiency Model from Eddy Covariance Flux Data for Predicting Daily Gross Primary Production Across Biomes 

      Wofsy, Steven; Goulden, Michael L.; Vesala, Timo; Baldocchi, Dennis; Bernhofer, Christian; Ameriflux Collaborators; Gholz, Henry; Yuan, Wenping; Tieszen, Larry L.; Liu, Shuguang; Zhou, Guangsheng; Zhou, Guoyi; Hu, Yueming; Stoy, Paul C.; Law, Beverly E.; Hollinger, David Y.; Goldstein, Allen H. (Elsevier, 2007)
      The quantitative simulation of gross primary production (GPP) at various spatial and temporal scales has been a major challenge in quantifying the global carbon cycle. We developed a light use efficiency (LUE) daily GPP ...

    • Estimation of Net Ecosystem Carbon Exchange for the Conterminous United States by Combining MODIS and AmeriFlux Data 

      Drake, Bert G.; Richardson, Andrew D.; Cook, David R.; Bolstad, Paul V.; Curtis, Peter S.; Zhuang, Qianlai; McNulty, Steve; Martin, Timothy A.; Matamala, Roser; Hadley, Julian L.; Suyker, Andrew E.; Ma, Siyan; Wofsy, Steven; Wharton, Sonia; Sun, Ge; Torn, Margaret S.; Xiao, Jingfeng; Starr, Gregory; Burns, Sean P.; Foster, David R.; Fischer, Marc L.; Scott, Russell L.; Gu, Lianhong; Verma, Shashi B.; Katul, Gabriel G.; Hollinger, David Y.; Noormets, Asko; Law, Beverly E.; Schmid, Hans Peter; Falk, Matthias; Monson, Russell K.; Meyers, Tilden P.; Litvak, Marcy; Munger, J. William; Oechel, Walter C.; Paw U, Kyaw Tha; Baldocchi, Dennis D.; Chen, Jiquan; Oren, Ram (Elsevier, 2008)
      Eddy covariance flux towers provide continuous measurements of net ecosystem carbon exchange (NEE) for a wide range of climate and biome types. However, these measurements only represent the carbon fluxes at the scale of ...

    • Linking Flux Network Measurements to Continental Scale Simulations: Ecosystem Carbon Dioxide Exchange Capacity under Non-Water-Stressed Conditions 

      Geyer, Ralf; Wang, Quan; Tenhunen, John; Falge, Eva; Vogel, Chris; Heinesch, Bernard; Gruenwald, Thomas; Hadley, Julian; Aurela, Mika; Saigusa, Nobuko; Owen, Katherine E.; Pilegaard, Kim; Verma, Shashi; Vesala, Timo; Reichstein, Markus; Arain, Altaf; Ammann, Christof; Moureaux, Christine; Aubinet, Marc; Xiao, Xiangming; Chojnicki, Bogdan; Bernhofer, Christian; Moors, Eddy; Stoy, Paul; Knohl, Alexander; Hollinger, David; Granier, Andre; Kutsch, Werner; Lohila, Annalea; Meyers, Tilden (Blackwell Science, 2007)
      This paper examines long-term eddy covariance data from 18 European and 17 North American and Asian forest, wetland, tundra, grassland, and cropland sites under non-water-stressed conditions with an empirical rectangular ...

    • A Multi-Site Analysis of Random Error in Tower-Based Measurements of Carbon and Energy Fluxes 

      Davis, Kenneth J.; Suyker, Andrew E.; Munger, J. William; Wofsy, Steven; Katul, Gabriel G.; Ricciuto, Daniel M.; Stoy, Paul C.; Flanagan, Lawrence B.; Richardson, Andrew D.; Hollinger, David Y.; Burba, George C.; Verma, Shashi B. (Elsevier, 2006)
      Measured surface-atmosphere fluxes of energy (sensible heat, <i>H</i>, and latent heat, LE) and CO2 (<i>F</i>CO2) represent the "true" flux plus or minus potential random and systematic measurement errors. Here, we use data ...

    • Soil Respiration in a Northeastern US Temperate Forest: A 22-Year Synthesis 

      Giasson, M.-A.; Ellison, Aaron M.; Bowden, R. D.; Crill, P. M.; Davidson, E. A.; Drake, J. E.; Frey, S. D.; Hadley, J; Lavine, M.; Melillo, J. M.; Munger, J. W.; Nadelhoffer, K. J.; Nicoll, L.; Ollinger, S. V.; Savage, K. E.; Steudler, P. A.; Tang, J.; Varner, R. K.; Wofsy, Steven C.; Foster, David Russell; Finzi, A. C. (Ecological Society of America, 2013)
      To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter-annual variations in soil respiration (R\(_{s}\)), we analyzed more than 100,000 ...
