Evolution of superficial lake water temperature profile under diurnal radiative forcing

Ulrich Lemmin, Wolf Hendrik Huwald, Marc Parlange, Ivan Lunati, Nikki Vercauteren

In lentic water bodies, such as lakes, the water temperature near the surface typically increases during the day, and decreases during the night as a consequence of the diurnal radiative forcing (solar and infrared radiation). These temperature variations ...

Field study of the dynamics and modelling of subgrid-scale turbulence in a stable atmospheric surface layer over a glacier

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Charles Vivant Ignacio Meneveau

A field experiment – the Snow Horizontal Array Turbulence Study (SnoHATS) – has been performed over an extensive glacier in Switzerland in order to study small-scale turbulence in the stable atmospheric surface layer, and to investigate the role, dynamics ...

Stream Temperature Response to Three Riparian Vegetation Scenarios by Use of a Distributed Temperature Validated Model

Martin Vetterli, Aurèle Parriaux, Wolf Hendrik Huwald, Marc Parlange, Guillermo Barrenetxea Kobas

Elevated in-stream temperature has led to a surge in the occurrence of parasitic intrusion proliferative kidney disease and has resulted in fish kills throughout Switzerland's waterways. Data from distributed temperature sensing (DTS) in-stream measurement ...

Albedo effect on radiative errors in air temperature measurements

Michael Lehning, Wolf Hendrik Huwald, Marc Parlange, Marc-Olivier Boldi, Chad Higgins

Most standard air temperature measurements are subject to significant errors mainly due to sensor heating by solar radiation, even when the measurement principle is accurate and precise. We present various air temperature measurements together with other m ...

Estimation of wet surface evaporation from sensible heat flux measurements

Wolf Hendrik Huwald, Marc Parlange, Nikki Vercauteren

A new method is proposed to estimate wet surface evaporation by means of measurements of sensible heat flux and of air temperature, relative humidity, and wind speed at one level only. This formulation is made possible by the linearization of the Bowen rat ...

Subgrid-Scale Dynamics of Water Vapour, Heat, and Momentum over a Lake

Ulrich Lemmin, Wolf Hendrik Huwald, Marc Parlange, Nikki Vercauteren, Charles Vivant Ignacio Meneveau

We examine the dynamics of turbulence subgrid (or sub-filter) scales over a lake surface and the implications for large-eddy simulations (LES) of the atmospheric boundary layer. The analysis is based on measurements obtained during the Lake-Atmosphere Turb ...

Distributed fiber-optic temperature sensing for hydrologic systems

Luc Thévenaz, Wolf Hendrik Huwald, Marc Parlange, Nicolaas Cornelis van de Giesen

Instruments for distributed fiber-optic measurement of temperature are now available with temperature resolution of 0.01°C and spatial resolution of 1 m with temporal resolution of fractions of a minute along standard fiber-optic cables used for communicat ...
