Interannual variation of the Bowen ratio in a subtropical coniferous plantation in southeast China, 2003-2012. [PDF]
The interannual variation of the Bowen ratio, through its effect on the warming extent of available energy to the ecosystem land surface air, heavily influences the ecosystem microclimate and affects the hydrological cycle at both regional and global ...

Modified formula for estimating the Bowen ratio – description of the determination procedure [PDF]
Aim of the study: One way of estimating evapotranspiration is to use the heat balance structure of active surface. Material and methods: The paper shows how to derive a formula estimating the Bowen ratio by using measurement data of heat balance ...

Intercomparison of sensible and latent heat flux measurements from combined eddy covariance, energy balance, and Bowen ratio methods above a grassland prairie [PDF]
We present a comparison of four different methods of measuring sensible (H) and latent (LE) heat fluxes for a year over a mixed grass prairie ecosystem in the Nebraska SandHills [eddy covariance (EC), energy balance/Bowen ratio (EBBR), residual energy ...

A new method to measure Bowen ratios using high-resolution vertical dry and wet bulb temperature profiles [PDF]
The Bowen ratio surface energy balance method is a relatively simple method to determine the latent heat flux and the actual land surface evaporation. The Bowen ratio method is based on the measurement of air temperature and vapour pressure gradients. If

Bowen‐Ratio Comparisons with Lysimeter Evapotranspiration [PDF]
AbstractWater use in agriculture by different cropping systems is of interest in determining crop water use efficiency of different tillage practices that will lead to reduced crop production risk. Lysimeters are considered the standard for evapotranspiration (ET) measurements; however, these units are often not replicated and are few in number at any ...

GUIDELINES FOR VALIDATING BOWEN RATIO DATA [PDF]
For a variety of reasons, the measurement of latent heat flux using the Bowen ratio method can sometimes result in erroneous data. This study provides guidelines for detecting erroneous Bowen ratio data and illustrates the application of these guidelines by comparing Bowen ratio and lysimeter data collected over grass and alfalfa in southern Idaho ...
