Spatial Distribution of Sensible and Latent Heat Flux in the City of Basel (Switzerland) [PDF]

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
Urban surfaces are a complex mixture of different land covers and surface materials; the relative magnitudes of the surface energy balance components therefore vary widely across a city. Eddy covariance (EC) measurements provide the best estimates of turbulent heat fluxes but are restricted to the source area.

Surface forcing of the North Atlantic: accuracy and variability [PDF]

open access: yes, 2009
A new methodology to estimate the turbulent air – sea heat and moisture fluxes andtheir uncertainty is developed and assessed using Voluntary Observing Ship (VOS)observations.

An inter-comparison of six latent and sensible heat flux products over the Southern Ocean [PDF]

open access: yesPolar Research, 2011
The latent heat fluxes (LHF) and sensible heat fluxes (SHF) over the Southern Ocean from six different data sets are inter-compared for the period 1988–2000.

Estimation of sensible heat, water vapor, and CO2 fluxes using the flux-variance method [PDF]

open access: yesInternational Journal of Biometeorology, 2008
This study investigated the flux-variance relationships of temperature, humidity, and CO(2), and examined the performance of using this method for predicting sensible heat (H), water vapor (LE), and CO(2) fluxes (F(CO2)) with eddy-covariance measured flux data at three different ecosystems: grassland, paddy rice field, and forest.

Evaluation of the Planetary Boundary Layer Height in China Predicted by the CMA-GFS Global Model

open access: yesAtmosphere, 2022
The key role of the planetary boundary layer height (PBLH) in pollution, climate, and model forecasting has long been recognized. However, the observed PBLH has rarely been used to evaluate numerical weather prediction models in China.

On Moisture Flux of the Indian Summer Monsoon: A New Perspective

open access: yesGeophysical Research Letters, 2019
Moisture flux is the driver of the Indian summer monsoon on all space‐time scales and its accurate representation in monsoon simulation models is crucial.

Assessing electron heat flux dropouts as signatures of magnetic field line disconnection from the Sun [PDF]

open access: yes, 2005
Suprathermal electrons focused along magnetic field lines, called the strahl, carry heat flux away from the Sun. Various factors can cause heat flux dropouts (HFDs), including times when the strahl almost vanishes.

Micrometeorology and heat balance over the fast ice

open access: yesAntarctic Record, 1997
Micrometeorological conditions were observed over fast ice with overlying thick snow cover and underlying deep sea approximately in the center of Ongul Strait in Lutzow-Holm Bay, Antarctica, from the end of March to the beginning of December in 1990.

Heat storage in forest biomass improves energy balance closure [PDF]

open access: yesBiogeosciences, 2010
Temperature measurements in trunks and branches in a mature ca. 100 years-old mixed pine and spruce forest in central Sweden were used to estimate the heat storage in the tree biomass.

Sensible Heat Flux Measurements Near A Cold Surface [PDF]

open access: yes, 1995
Abstract : A unidirectional sonic anemometer with a fine wire thermocouple in conjunction with a hot film anemometer were employed to measure the turbulent fluctuating velocities of w', u' and the fluctuating temperature T'. Covariances were evaluated to compute the turbulent heat flux and the friction velocity.
