Variation Characteristics of Surface Fluxes on Different Underlying Surfaces and Their Relationship with Precipitation in the Canyon Area of Southeast Tibet

open access: yesGaoyuan qixiang, 2022
In this study, variation characteristics of surface fluxes were analyzed by using the eddy covariance observations from four stations of Pailong, Danka, Kabu, and Motuo in the southeastern gorge area of Tibet from November 2018 to October 2019.Pailong ...

Sensible Heat Flux From Arid Regions: A Simple Flux‐Variance Method [PDF]

open access: yesWater Resources Research, 1995
Similarity models in the inner region of the unstable atmospheric boundary layer (ABL) are generally based on four dimensional parameters: buoyancy, friction velocity, surface heat flux, and the height above the land surface. In the free convection limit the friction velocity can be neglected, thus reducing the measurement needs in practical ...

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 ...

Sensible Heat Fluxes over an Urban Area—Vancouver, B.C. [PDF]

open access: yesJournal of Applied Meteorology, 1974
The use of the eddy correlation technique is demonstrated for the measurement of sensible heat transfer in an urban area. The problems of time and space sampling (in the horizontal and vertical) are investigated. Based on 27 summer days of observations from a roof-top site in the central built-up part of Vancouver, the diurnal variation of sensible ...

Review of approaches for the estimation of sensible heat flux in remote sensing-based evapotranspiration models

open access: yesJournal of Applied Remote Sensing, 2020
. We recapitulate the approaches of sensible heat flux (H) estimation, which is a critical parameter in the remote sensing (RS)-based evapotranspiration (ET) models.

Measuring sensible heat flux with high spatial density [PDF]

open access: yes2012 IEEE Sensors Applications Symposium Proceedings, 2012
Sensible heat flux is an essential quantity in the surface energy budget. Information about it is crucial for the derivation of models of air-surface interaction which in turn are needed for larger scale climate models. Sensible heat flux varies greatly across short distances and thus many sensors are required in order to obtain measurements of ...

Effects of Rooftop Photovoltaics on Building Cooling Demand and Sensible Heat Flux Into the Environment for an Installation on a White Roof

open access: yes, 2020
Photovoltaic (PV) panels are commonly used for on-site generation of electricity in urban environments, specifically on rooftops. However, their implementation on rooftops poses potential (positive and negative) impacts on the heating and cooling ...
