Rainfall retrieval with commercial microwave links in Sao Paulo, Brazil

In the last decade there has been a growing interest from the hydrometeorological community regarding rainfall estimation from commercial microwave link (CML) networks. Path-averaged rainfall intensities can be retrieved from the signal attenuation between ...

Energy integration of CO2 networks and Power to Gas for emerging energy autonomous cities in Europe

François Maréchal, Luc Girardin, Raluca-Ancuta Suciu

The concept of urban CO2 networks has been developed to deploy heat pump based district heating and cooling systems in dense urban areas. The use of the CO2 phase change reduces the cost of the heat distribution while allowing to recover waste heat that is ...

Reliability of photovoltaic modules

Eleonora Annigoni

A fundamental challenge with solar energy is improving the reliability, and increasing the lifetime, of photovoltaic modules. Typically, photovoltaic module manufacturers guarantee 80% of the nominal power of their modules for 25 years, but this type of gu ...

Silicon heterojunction solar cells: Recent technological development and practical aspects - from lab to industry

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Olivier Denis Dupré

We review the recent progress of silicon heterojunction (SHJ) solar cells. Recently, a new efficiency world record for silicon solar cells of 26.7% has been set by Kaneka Corp. using this technology. This was mainly achieved by remarkably increasing the fi ...

The role of glacier retreat for Swiss hydropower production

Pedro Filipe De Almeida Manso, Bettina Schaefli

High elevation or high latitude hydropower production (HP) strongly relies on water resources that are influenced by glacier melt and are thus highly sensitive to climate warming. Despite of the wide-spread glacier retreat since the development of HP infra ...

Mountain Snow Distribution and how it may Change in the Future

Michael Lehning, Wolf Hendrik Huwald

The spatial distribution of snow in the mountains is highly heterogeneous, and processes behind this heterogeneity are not yet understood quantitatively. Based on (i) increasing accuracy and spatial coverage of remotely sensed snow depth maps, which have b ...

Measurement of ammonia emissions from temperate and sub-polar seabird colonies

Julia Schmale

The chemical breakdown of marine derived reactive nitrogen transported to the land as seabird guano represents a significant source of ammonia (NH3) in areas far from other NH3 sources. Measurements made at tropical and temperate seabird colonies indicate ...

Une nouvelle infrastructure publique sur les rives du Bouveret

Sophie Langel

Le site choisi est celui du village du Bouveret, situé dans la plaine du delta du Rhône chablaisien suisse. Ce lieu est caractérisé principalement par son isolement: d'une part par sa situation au sein d'un territoire lui-même isolé, le Chablais suisse, d' ...

Lake surface temperatures in a changing climate: a global sensitivity analysis

Alfred Johny Wüest, Martin Schmid, Stefan Hunziker

We estimate the effects of climatic changes, as predicted by six climate models, on lake surface temperatures on a global scale, using the lake surface equilibrium temperature as a proxy. We evaluate interactions between different forcing variables, the se ...
