Psychrometric apparatus for Bowen-ratio determination over forests

Boundary-Layer Meteorology, 1971
The psychrometric apparatus design for Bowen ratio determination reported previously by Sargeant and Tanner was modified and a new apparatus built. Modification of the intake design improved the symmetry and rigidity of the sensor mounting. Wet- and dry-bulb differences were measured with an error less than 0.01 °C over a vertical distance of 1 m ...

Bowen Ratio Estimates over Lake Erie

Journal of Great Lakes Research, 2004
Estimates of the ratio of sensible heat flux to latent heat flux (the Bowen ratio) are derived for Lake Erie based on the method introduced by Roll (1965), using hourly automated observations of lake and air temperatures for Buoy 45005 for the period 1992–1997 (May through November).

Evapotranspiration - How Good is the Bowen Ratio Method?

Agricultural Water Management, 1984
Abstract Under moist conditions, the energy balance approach to determining evapotranspiration from plant communities can give good results, but the method may not be nearly so accurate under very dry conditions, or with considerable advection of energy in moist conditions.

Comparison of bowen ratio and aerodynamic estimates of evapotranspiration

Agricultural and Forest Meteorology, 1990
Abstract The energy balance of an irrigated cotton field was determined using the Bowen ratio to partition between sensible and latent heat flux density. These data verified estimates of the sensible heat flux density derived from either profiles of wind and temperature at six levels, or from a simplified aerodynamic method using wind and temperature

A Simple Psychrometric Apparatus for Bowen Ratio Determinations

Journal of Applied Meteorology, 1967
Abstract A simple apparatus has been devised which automatically reverses the vertical positions of two pairs of shielded and aspirated wet- and dry-bulb diodes. Analog voltage signals proportional to the dry and wet bulb temperatures T and Tw and to the differences ΔT and ΔTw are provided.

Precision of evaporation measurements using the Bowen ratio

Boundary-Layer Meteorology, 1976
Energy balance/Bowen ratio estimation of evapotranspiration is examined to determine the effects of different sources of error. General usage of the approximate psychrometric equation which neglects terms of order 1/p (p atmospheric pressure) can lead to large bias errors if the wet-bulb temperature depression is large.
