Direct computation of the sensible heat flux

Geophysical Research Letters, 1980
An algorithm to determine the sensible heat flux from simple field measurements (wind speed, air and ground temperatures) has been developed. It provides a direct solution, in parametric form, which can be displayed graphically or tabularly. This method has an advantage over the previous iterative solution in that the computation is fast.

Estimation of Sensible and Latent Heat Fluxes from Different Ecosystems Using the Daily-Scale Flux Variance Method

Atmosphere
A daily-scale flux variance (FV) method, which employs low-frequency air temperature measurements, was assessed against eddy covariance (EC) measurements of sensible and latent heat fluxes at four sites representing grassland and cropland ecosystems. The

The Impact of Biomass Heat Storage on the Canopy Energy Balance and Atmospheric Stability in the Community Land Model

Journal of Advances in Modeling Earth Systems, 2019
Atmospheric models used for weather prediction and future climate projections rely on land models to calculate surface boundary conditions. Observations of near‐surface states and fluxes made at flux measurement sites provide valuable data with which to ...

In Situ Measurements of Sensible Heat Fluxes in a Tropical Cyclone

Geophysical Research Letters
AbstractSensible heat fluxes play a major role in the formation and dynamics of Tropical Cyclones (TC), however in situ measurements of these fluxes have been impeded by the challenging and extreme conditions associated with these events. We used two sonic anemometers elevated at fixed height above the mean ocean surface to measure sensible heat fluxes

Field Observations and Modeling of Surfzone Sensible Heat Flux [PDF]

Journal of Applied Meteorology and Climatology, 2018
AbstractSurfzone sensible heat flux (HS,SZ) obtained through direct eddy-covariance estimates was measured at four different sandy beach sites along Monterey Bay, California. The HS,SZ source region is estimated from a footprint probability distribution function (pdf) model and is only considered when at least 70% of the footprint pdf occupies the ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Spatialization of sensible heat flux over a heterogeneous landscape [PDF]

Agronomie, 2002
Deux methodes d'estimation du flux de chaleur sensible sur une surface composite sol nu/ble sont comparees. La premiere repose sur des mesures de terrain au moyen de scintillometres a grande ouverture. La comparaison avec des mesures de reference effectuees par la technique des correlations revele une surestimation de 10 % sur les flux obtenus par ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Sensible Heat Flux Measurements Near A Cold Surface [PDF]

, 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.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
