Small-scale and mesoscale lake surface water temperature structure: Thermography and in situ measurements from Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

Lake surface water temperature (LSWT), which varies spatially and temporarily, reflects meteorological and climatological forcing more than any other physical lake parameter. There are different data sources for LSWT mapping, including remote sensing and i ...

Thermal Circulation Patterns and Turbulent Fluxes along Steep Mountain Slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau, Fabian Bärenbold

In hydrology, it is crucial to understand the atmospheric flow dynamics in mountainous terrain to predict turbulent exchanges of heat and moisture accurately at the regional scale. Under clear skies and weak synoptic conditions, these land–atmosphere inter ...
