An attenuated eddy covariance method for latent heat flux measurements [PDF]

open access: bronzeWater Resources Research, 2007
An attenuated eddy covariance (AEC) method is proposed, combining the use of a relatively robust three‐dimensional sonic anemometer and a ventilated capacitive hygrometer‐thermometer (CHT). The CHT is able to resolve a large enough frequency region of the water vapor density turbulent fluctuations to allow corrections for its limited time response in ...

A Study of the Influence of Environmental Factors on Water–Heat Exchange Process in Alpine Wetlands

open access: yesAtmosphere, 2023
Wetlands, which are composed of soil, vegetation and water, have sufficient water supply and are sensitive to climate change. This study analyzes the coupling degree between wetlands and atmosphere and discusses the influence of environmental factors ...

Estimation of Corn Latent Heat Flux from High Resolution Thermal Imagery

open access: yesRemote Sensing, 2022
Crop evapotranspiration (ET), which is directly related to latent heat flux, is also a key indicator in determining the water status of crops. In order to estimate the latent heat flux, two-source energy balance (TSEB) models have been developed for ...

The Characteristics of Land‐Atmospheric Water and Heat Exchange during Soil Freezing‐Thawing Process over the Underlying Surface of the Alpine Grassland in the Source Region of the Yellow River

open access: yesGaoyuan qixiang, 2022
The seasonal characteristics of water and heat exchange in the alpine grasslands are significant, and the freezing‐thawing process has an important impact on the land‐atmospheric water and heat exchange.Based on the observation data of the land surface ...

Air-sea flux and SST variability associated with atmospheric rivers in the southeast Indian Ocean

open access: yesFrontiers in Climate, 2023
A previous study demonstrated that atmospheric rivers (ARs) generate substantial air-sea fluxes in the northeast Pacific. Since the southeast Indian Ocean is one of the active regions of ARs, similar air-sea fluxes could be produced. However, the spatial
