Estimating the soil temperature profile from a single depth observation: A simple empirical heatflow solution [PDF]

Water Resources Research, 2008
Two field data sets are used to model near‐surface soil temperature profiles in a bare soil. It is shown that the commonly used solutions to the heat flow equations by Van Wijk perform well when applied at deeper soil layers, but result in large errors when applied to near surface layers, where more extreme variations in temperature occur.

Reply to comment by J. Wang and R. L. Bras on “Estimating the soil temperature profile from a single depth observation: A simple empirical heatflow solution” [PDF]

Water Resources Research, 2009
[1] We welcome the comments by Wang and Bras [2009] on our recent paper [Holmes et al., 2008]. The comments by the authors indicate that the way we presented our novel approach, which considers the effect of extending part of the surface energy balance components to below the ground surface, raises questions and warrants a more comprehensive discussion.

Solvation Entropy as a Lever for Steering the Macroscopic Properties of a Functional Supramolecular Helical Polymer. [PDF]

Angew Chem Int Ed Engl
The structural transition between the two fully‐characterized states of a supramolecular helical hydrogen‐bonded polymer (represented as blue and light pink stacks) can be predictably varied over 85 K by changing the nature and amount of cosolvent; entropy of solvation (schematized as solvents of different sizes) is the main lever to tune the ...

Combining CFD simulations with blockoriented heatflow-network model for prediction of photovoltaic energy-production [PDF]

Journal of Physics: Conference Series, 2011
The exterior factors which influencing the working circumstances of photovoltaic modules are the irradiation, the optical air layer (Air Mass – AM), the irradiation angle, the environmental temperature and the cooling effect of the wind. The efficiency of photovoltaic (PV) devices is inversely proportional to the cell temperature and therefore the ...

Strong Physical Contrasts Across Two Mid‐Lithosphere Discontinuities Beneath the Northwestern United States: Evidence for Cratonic Mantle Metasomatism

AGU Advances, Volume 4, Issue 6, December 2023., 2023
Abstract Mid‐lithosphere discontinuities are seismic interfaces likely located within the lithospheric mantle of stable cratons, which typically represent velocities decreasing with depth. The origins of these interfaces are poorly understood due to the difficulties in both characterizing them seismically and reconciling the observations with thermal ...
