The role of surface roughness, albedo, and Bowen ratio on ecosystem energy balance in the Eastern United States [PDF]

open access: yes, 2018
Land cover and land use influence surface climate through differences in biophysical surface properties, including partitioning of sensible and latent heat (e.g., Bowen ratio), surface roughness, and albedo.

Bowen ratio estimates of evapotranspiration for stands on the Virgin River in Southern Nevada [PDF]

open access: yes, 1998
A Bowen ratio energy balance was conducted over a Tamarix ramosissima (saltcedar) stand growing in a riparian corridor along the Virgin River in southern Nevada.

Case Study of Pollutants Concentration Sensitivity to Meteorological Fields and Land Use Parameters over Douala (Cameroon) Using AERMOD Dispersion Model

open access: yesAtmosphere, 2011
This paper deals with the simulation of the NOx concentration over Douala for the period 2002–2006 by means of the American Meteorological Society (AMS)/Environmental Protection Agency (EPA) Regulatory Model (AERMOD) model, version 07026. Its sensitivity

Relative Humidity as an Indicator for Cloud Formation over Heterogeneous land surfaces [PDF]

open access: yes, 2008
The influence of land surface heterogeneity on potential cloud formation is investigated using relative humidity as an indicator. This is done by performing numerical experiments using a large-eddy simulation model (LES).

Bowen ratio and evapotranspiration dynamics of oil palm

open access: yesInternational Journal of Tropical Drylands, 2023
Abstract. Asyura MF, June T, Salmayenti R. 2023. Bowen ratio and evapotranspiration dynamics of oil palm. Intl J Trop Drylands 7: 37-45. To optimize its biophysical processes, plant needs water and this requirement can be quantified as Evapotranspiration (ET).

Actual evapotranspiration from partially tile-drained fields as influenced by soil properties, terrain and crop

open access: yesSoil and Water Research, 2011
Physical properties of soils have a significant influence on their water regime and should be considered when selecting suitable agricultural crops for particular sites, taking into account the crop productivity and its water requirements.

Modelling the partitioning of turbulent fluxes at urban sites with varying vegetation cover [PDF]

open access: yes, 2016
Inclusion of vegetation is critical for urban land surface models (ULSM) to represent reasonably the turbulent sensible and latent heat flux densities in an urban environment.

Measurements of the actual evapotranspiration and crop coefficients of summer and winter seasons crops in Japan

open access: yesPlant, Soil and Environment, 2009
The main goal was to understand the trends of actual evapotranspiration (AET) and crop coefficient (Kc) in summer and winter seasons crops in Japan, maize, soybean, wheat and Italian rye-grass.

Evapotranspiration of riparian ecosystems and irrigated cotton agriculture at the middle reaches of the Tarim River, Xinjiang, China

open access: yesCentral Asian Journal of Water Research, 2017
In the steppes, semi-deserts, and deserts of Central Asia the most productive ecosystems are riparian ecosystems like forests and shrublands. Rivers also serve as the water source for irrigation so that the major settlements and oases of the region are ...

The effect of Surface Heterogeneity on the Temperature-Humidity Correlation and the Relative Transport Efficiency [PDF]

open access: yes, 2008
We derive a conceptual model of the flow over heterogeneous terrain consisting of patches with contrasting Bowen ratios. Upward moving eddies are assumed to carry heterogeneous properties, whereas downward moving eddies carry homogeneous properties. This
