The Energy Budget at the E ARTH3S Surface: Estimation of Turbulent Exchange Within a CORN Crop Canopy at Ellis Hollow, N. Y., 1961.
Abstract
Two days of heated thermocouple and cup anemometer data, and one day of carbon dioxide data taken at several levels within and above a corn crop are assembled. Vertical transfer coefficients are determined by the analysis of wind speed fluctuations using selected 30-second periods of semi-steady wind trace assuming isotropy. These are compared with those obtained using the logarithmic profile method, the fluctuation method giving values several times larger. A possible explanation is that the assumption of isotropy is not justified. The transfer rates of carbon dioxide as calculated from the exchange coefficients and carbon profiles are presented.
