Variability of the Rain Drop Size Distribution

Precipitation is an important component of the Earth' water cycle and needs to be carefully monitored. Its large variability over a wide range of spatial and temporal scales must be taken into account. For example, hydrological models require accurate rain ...

High-resolution vertical profiles of polarimetric X-band weather radar observables during snowfall in the Swiss Alps

Michael Lehning, Alexis Berne, Marc Schneebeli Zeugin

An X-band polarimetric radar was deployed in the eastern Swiss Alps at an altitude of 2133 m. Radar measurements were complemented with several weather stations deployed in an altitude range from 1500 to 3100 m as well as with a fixed GPS ground station th ...

Variability of Rainfall in a Semi-Arid Catchment in Burkina Faso

Christine Wiedmann

The climate in the Sahel is marked by the spatial and temporal variability of rainfall. As the agriculture is mainly rainfed in Burkina Faso, the information about rainfall is crucial to help the farmers in their decisions. A network of wireless sensorscop ...

All additive inkjet printed humidity sensors on plastic substrate

Nico de Rooij, Danick Briand, Francisco Molina Lopez

Functional humidity sensors have been fabricated on polymeric foil PET using all additive processes. The fabrication included inkjet printing and electrodeposition of interdigitated structures followed by the inkjet printing of a test humidity sensing laye ...

Sparsity Averaging Reweighted Analysis (SARA): a novel algorithm for radio-interferometric imaging

Yves Wiaux, Rafael Eduardo Carrillo Rangel, Jason Douglas McEwen

We propose a novel algorithm for image reconstruction in radio interferometry. The ill-posed inverse problem associated with the incomplete Fourier sampling identified by the visibility measurements is regularized by the assumption of average signal sparsi ...

Hydrologic response of an alpine watershed: Application of a meteorological wireless sensor network to understand streamflow generation

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Marc Diebold, François Ingelrest, Simone Padoan, Silvia Simoni

A field measurement campaign was conducted from June to October 2009 in a 20 km2 catchment of the Swiss Alps with a wireless network of 12 weather stations and river discharge monitoring. The objective was to investigate the spatial variability of meteorol ...

Extreme temperature analysis under forest cover compared to an open field

Anthony Christopher Davison, Martine Rebetez, Jacques Ferrez

We analyse air temperature data from 14 sites in Switzerland, each with two weather stations in close proximity, one under a forest canopy and the other in the open. We use the statistics of extremes to investigate how extremely high maximum and extremely ...

Hydrological monitoring and modeling of an alpine catchment

Andrea Rinaldo, Marc Parlange, Steven Vincent Weijs, Raphaël Mutzner

Since 2008 we have been monitoring a watershed in the alps to assess the impact of the spatial heterogeneity of meteorological variables over a complex terrain and identify the mechanisms generating streamflow. The study area is located in the Swiss Alps a ...

Relating the X-band Opacity of a Tropical Tree Canopy to Sapflow, Rain Interception and Dew Formation

Marc Schneebeli Zeugin

During summer and autumn 2007, a 11 GHz microwave radiometer was deployed in an experimental tree plantation in Sardinilla, Panama. The opacity of the tree canopy was derived from incoming brightness temperatures received on the ground. A collocated eddy-c ...
