It is suggested that in all conditions of stability either of two slightly different profile equations can be used, both carrying in-built stability weighting factors for use in transport equations. Setting Λ = In(z—d)/z0 the more convenient equat

The coefficient of turbulent diffusion was measured in a 1·25m tall wheat canopy using a uniform release of nitrous oxide, the energy and momentum balance methods, and the humidity profile. The nitrous oxide profile gave the most accurate values, KN

Wind and temperature profiles were measured above irrigated and non-irrigated field beans in 1972, and potatoes in 1973, and the zero-plane displacement d and roughness length z 0 were derived. For both crops the ratios of d and z 0 to crop height h

Several instruments suitable for long-term recording of temperature, humidity and wind gradients among growing crops have been constructed. Practical details are given of the use of thermistors and miniature nickel resistance thermometers as wet- and

Data for three summers (1955-1957) are presented, obtained from continuous recorders responding to temperature, humidity and wind in and above the wheat crop at levels up to about 2 m. Section 1 gives a brief account of the instruments (see Long, Q.J

Three analytic and two emperic methods are described to calculate the surface resistance rs of crops transpiring at a measured rate. The profile method is applicable when detailed temperature, humidity, and wind profiles are measured; for the residua

Evaporation from field crops can be estimated using formulae that treat the crop as a single surface. Some formulae allow for different crop types and for changes in crop structure with growth, by including an aerodynamic resistance that is a functio
