  • Processing arctic eddy-flux data using a simple carbon-exchange model embedded in the ensemble Kalman filter 

    Rastetter, Edward B.; Williams, Mathew; Griffin, Kevin L.; Kwiatkowski, Bonnie L.; Tomasky, Gabrielle; Potosnak, Mark J.; Stoy, Paul C.; Shaver, Gaius R.; Stieglitz, Marc; Hobbie, John E.; Kling, George W. (Ecological Society of America, 2010-07)
    Continuous time-series estimates of net ecosystem carbon exchange (NEE) are routinely made using eddy covariance techniques. Identifying and compensating for errors in the NEE time series can be automated using a signal ...
  • Recovery from disturbance requires resynchronization of ecosystem nutrient cycles 

    Rastetter, Edward B.; Yanai, Ruth D.; Thomas, R. Q.; Vadeboncoeur, M. A.; Fahey, Timothy J.; Fisk, M. C.; Kwiatkowski, Bonnie L.; Hamburg, S. P. (Ecological Society of America, 2013-04)
    Nitrogen (N) and phosphorus (P) are tightly cycled in most terrestrial ecosystems, with plant uptake more than 10 times higher than the rate of supply from deposition and weathering. This near-total dependence on recycled ...
  • A stable isotope simulator that can be coupled to existing mass balance models 

    Rastetter, Edward B.; Kwiatkowski, Bonnie L.; McKane, Robert B. (2005-01-07)
    To facilitate the simulation of isotope dynamics in ecosystems, we developed software to model changes in the isotopic signatures of the stocks of an element using the output from any parent model that specifies the stocks ...
