Measurement of the impact of buildings on meteorological variables

Jean-Louis Scartezzini, Dasaraden Mauree, Laurent Deschamps, Pierre Loesch, Paul Becquelin

A meteorological tower was installed on the EPFL campus in a semi-urban environment for the high frequency monitoring of the micro-climate. This project was done in the larger framework of the measurement of the meteorological profiles and also a quantific ...

Tomography-based radiative characterisation of decomposing carbonaceous heat shield materials

Sophia Haussener, Pénélope Leyland, Nikhil Banerji

This work evaluates the changes in radiative properties of two decomposing carbonaceous porous materials, each composed of two semitransparent, homogeneous and isotropic phases. The understanding of the complex dependence of macroscopic optical behaviour o ...

High-flux optical systems for solar thermochemistry

Sophia Haussener, Gaël Jean Clément Levêque

High-flux optical systems (HFOSs) are optical concentrators used to increase the radiative flux of the natural terrestrial solar irradiation. High radiative flux concentration leads to high energy density in solar receivers which allow to obtain high tempe ...

Mountain shading influence on spatial interpolation of direct shortwave radiation for snowmelt modeling

The hydrology of alpine areas is highly snow-dependent. Snowmelt, as a major component of the hydrologic cycle, influences the streams hydrology and biogeochemistry and is important to take into account in water resources management. Modeling snow distribu ...

Negative elevation-dependent warming trend in the Eastern Alps

Mountain regions and the important ecosystem services they provide are considered to be very vulnerable to the current warming, and recent studies suggest that high-mountain environments experience more rapid changes in temperature than environments at low ...

Spatial estimates of snow water equivalent from reconstruction

Annelen Kahl

Operational ground-based measurements of snow water equivalent (SWE) do not adequately explain spatial variability in mountainous terrain. To address this problem, we combine satellite-based retrievals of fractional snow cover for the period 2000 to 2011 w ...

Operational snowcover simulations with avalanche dynamics calculations coupling to assess avalanche danger in high altitude mining operations

Nander Wever

The Codelco Andina copper mine is operating in high alpine terrain where avalanches pose a threat to the operations and the infrastructure. A dedicated avalanche warning service is responsible for opening and closing the heavily used access road. To suppor ...

Carbon storage versus albedo change: radiative forcing of forest expansion in temperate mountainous regions of Switzerland

Michael Lehning, Marc Schneebeli Zeugin, Mathias Thierry Pierre Bavay

In this study, we assess the climate mitigation potential from afforestation in a mountainous snow-rich region (Switzerland) with strongly varying environmental conditions. Using radiative forcing calculations, we quantify both the carbon sequestration pot ...

Simulations of 21st century snow response to climate change in Switzerland from a set of RCMs

Michael Lehning, Charles Fierz

Twenty-first century snow depth and snow water equivalent (SWE) changes are assessed for three time periods (2020-2049, 2045-2079 and 2070-2099) at 11 stations in Switzerland with the physics-based snow model SNOWPACK and meteorological input data perturbe ...

Heat flux modifications related to climate-induced warming of large European lakes

Alfred Johny Wüest, Martin Schmid

Within the last decades, the water temperature of several European lakes has risen. It is assumed that these temperature increases are due to a reconfiguration of the heat-balance components. This study explores the dominant modifications of heat exchange ...
