Analysis of soil carbon transit times and age distributions using network theories
(Journal of Geophysical Research: Biogeosciences, 2009-01-01)The long-term soil carbon dynamics may be approximated by networks of linear compartments, permitting theoretical analysis of transit time (i.e., the total time spent by a molecule in the system) and age (the time elapsed ... -
Boom and bust carbon-nitrogen dynamics during reforestation
(Ecological Modelling, 2017-09-24)© 2017 Elsevier B.V. Legacies of historical land use strongly shape contemporary ecosystem dynamics. In old-field secondary forests, tree growth embodies a legacy of soil changes affected by previous cultivation. Three patterns ... -
Causality across rainfall time scales revealed by continuous wavelet transforms
(JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES, 2010-07-31) -
Estimation of in-canopy ammonia sources and sinks in a fertilized Zea mays field.
(Environ Sci Technol, 2010-03-01)An analytical model was developed to describe in-canopy vertical distribution of ammonia (NH(3)) sources and sinks and vertical fluxes in a fertilized agricultural setting using measured in-canopy mean NH(3) concentration ... -
Estimation of long-term basin scale evapotranspiration from streamflow time series
(Water Resources Research, 2010-10-29)We estimated long-term annual evapotranspiration (ETQ) at the watershed scale by combining continuous daily streamflow (Q) records, a simplified watershed water balance, and a nonlinear reservoir model. Our analysis used ... -
Predicting the dry deposition of aerosol-sized particles using layer-resolved canopy and pipe flow analogy models: Role of turbophoresis
(Journal of Geophysical Research Atmospheres, 2010-01-01)A number of synthesis activities, mathematical modeling, and experiments on dry deposition of aerosol-sized particles over forested surfaces point to three disjointed findings: (1) deposition velocities measured over tall ... -
Role of microtopography in rainfall-runoff partitioning: An analysis using idealized geometry
(Water Resources Research, 2010) -
Scale-wise evolution of rainfall probability density functions fingerprints the rainfall generation mechanism
(Geophysical Research Letters, 2010-01-01)© 2010 by the American Geophysical Union.The cross-scale probabilistic structure of rainfall intensity records collected over time scales ranging from hours to decades at sites dominated by both convective and frontal systems ... -
The rainfall-no rainfall transition in a coupled land-convective atmosphere system
(Geophysical Research Letters, 2010-07-01)A one-dimensional representation of the atmospheric boundary layer (ABL) depth is coupled to a soil moisture bucket model to dynamically explore the relative roles of surface and free atmospheric conditions on convective ... -
Transport in a coordinated soil-root-xylem-phloem leaf system
(Advances in Water Resources, 2018-09)© 2018 Elsevier Ltd Links between the carbon and water economies of plants are coupled by combining the biochemical demand for atmospheric CO2with gas transfer through stomates, liquid water transport in the soil-xylem hydraulic ... -
Vegetation-infiltration relationships across climatic and soil type gradients
