Control of atmospheric fluxes from a pecan orchard by physiology, meteorology, and canopy structure: Modeling and measurement

Gutschick, Vincent P.; Sheng, Zhuping - In: Agricultural Water Management 129 (2013) C, pp. 200-211

We constructed and validated against eddy-covariance data a model of the fluxes of water vapor, sensible heat, CO2, and radiation in a substantially mature pecan orchard (Carya illinoinensis (Wangenh.)K. Koch) in an arid environment near El Paso, TX, USA. The detailed process-based model is...
