Under-ice convection dynamics in a boreal lake

Alfred Johny Wüest, Damien Bouffard, Sébastien Lavanchy, Hugo Nicolás Ulloa Sánchez

We investigated radiatively driven under-ice convection in Lake Onego (Russia) during 3 consecutive late winters. In ice-covered lakes, where the temperature of water is below the temperature of maximum density, radiatively driven heating in the upper wate ...

Correction of CCI cloud data over the Swiss Alps using ground-based radiation measurements

Alexis Berne, Fanny Alexia Jeanneret

The validation of long-term cloud data sets retrieved from satellites is challenging due to their worldwide coverage going back as far as the 1980s. A trustworthy reference cannot be found easily at every location and every time. Mountainous regions presen ...

Rainfall retrieval with commercial microwave links in Sao Paulo, Brazil

Timothy Hugh Raupach

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 ...

Modeling the effects of future urban planning scenarios on the Urban Heat Island in a complex region

Jean-Louis Scartezzini, Dasaraden Mauree, Sylvain Labedens

Because of the global warming, urban planning strategies must be investigated to reduce the building energy consumption and increase the thermal comfort in cities. In the framework of Energy Strategy 2050 of Switzerland, this research aim to highlight the ...

Local surface mass balance processes in East Antarctica

Varun Sharma, Michael Lehning, Wolf Hendrik Huwald, Nander Wever, Francesco Comola, Eric Sauvageat

In Antarctica, direct observations of key processes shaping the surface mass balance such as precipitation and snow deposition, wind transport of snow, and sublimation, are sparse due to the extreme environment and related difficulties in measuring the var ...

Improvement of Wind Power Assessment in Complex Terrain: The Case of COSMO-1 in the Swiss Alps

Michael Lehning, Jérôme François Sylvain Dujardin

This work contains a series of calculations that explore the wind power potential in Switzerland using the Numerical Weather Prediction model COSMO-1. The model's performance was validated in complex terrain by comparing the modeled hourly wind speed to we ...

Obstacle detection for lake-deployed autonomous surface vehicles using RGB imagery

David Andrew Barry, Philippe Olivier Paccaud

We describe and test an obstacle-detection system for small, lake-deployed autonomous surface vehicles (ASVs) that relies on a low-cost, consumer-grade camera and runs on a single-board computer. A key feature of lakes that must be accounted for is the fre ...

From model to radar variables: a new forward polarimetric radar operator for COSMO

Alexis Berne, Daniel Wolfensberger

In this work, a new forward polarimetric radar operator for the COSMO numerical weather prediction (NWP) model is proposed. This operator is able to simulate measurements of radar reflectivity at horizontal polarization, differential reflectivity as well a ...
