Application of harmonic analysis to ground heat flux determination by creating an artificial fundamental period

open access: yesMeteorologische Zeitschrift, 2019
In the context of eddy-covariance measurements of land-surface atmosphere energy exchange and energy balance studies, soil temperature, soil water content and soil flux data were measured in the years 2009–2015 at three closely neighbored agricultural ...

Observations of soil heat flux at Pune using a heat flux plate

open access: yesMAUSAM, 1980
Measurements of soil heat flux were made over bare black cotton soil at Pune in the period June 1976 to February 1977, using a soil heat flux plate. Hourly values of soil heat flux from 00 to 24 LAT are presented for selected days typical of the monsoon, post-monsoon and winter seasons.

Determination of land surface heat fluxes over heterogeneous landscape of the Tibetan Plateau by using the MODIS and in situ data [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
In this study, a parameterization methodology based on MODIS (Moderate Resolution Imaging Spectroradiometer) and in situ data is proposed and tested for deriving the regional surface reflectance, surface temperature, net radiation flux, soil heat flux ...

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 ...

Evaluation of the Soil, Vegetation, and Snow (SVS) Land Surface Model for the Simulation of Surface Energy Fluxes and Soil Moisture under Snow-Free Conditions

open access: yesAtmosphere, 2020
The recently developed Soil, Vegetation, and Snow (SVS) land surface model is being progressively implemented at Environment and Climate Change Canada (ECCC) for operational numerical weather and hydrological predictions.

Latent Heat Flux (Evapotranspiration) in Summer Season on Rooftop Greening Soil with Bamboo Charcoal Sublayer at a Building in West Japan

open access: yesGeofluids, 2021
The effect of a thin and light greening system with bamboo charcoal layer for water retention on heat fluxes, in particular latent heat flux (evapotranspiration rate), under no irrigation condition, on the rooftop of a building in Higashi-Hiroshima, West

Heat flow characteristics and thermal resistance model for soil-rock mixtures during freezing-thawing processes: Damping properties

open access: yesGeoderma, 2023
As a special heterogeneous geological material, soil-rock mixtures are widely distributed in nature and used in civil engineering. Heat flow is one of the most significant factors affecting the development of water balance and redistribution, ground ...

Modeling Soil Heat Flux in R

open access: yesJournal of Agricultural Informatics, 2014
Knowing of soil heat flow properties of a crop field inform the farmer about temperature conditions of seeds germination. Soil heat flow today is either measured or modeled. In our study we rely on the procedure developed by Sang-Ok Chung and Robert Horton (1987).

The surface heat flux density of a bare soil [PDF]

open access: yesAtmosphere-Ocean, 1983
Abstract Half‐hourly measurements of soil surface heat flux density (G0 ), solar irradiance (S), and the surface energy balance components were made at Agassiz, b.c., in the spring and early summer of 1978 at two adjacent bare‐soil sites, one of which was culti‐packed while the other was disc‐harrowed.

Spatiotemporal Rule of Heat Transfer on a Soil/Finned Tube Interface

open access: yesSensors, 2019
To efficiently harvest environmental micro-energy from shallow soil, simulated analysis, theoretical arithmetic and experimental verification are performed to explore the spatiotemporal rules of heat transfer on a soil/finned tube interface.
