Statistical analysis of the spatial and temporal variability of polarimetric weather radar signals in the Alps
Floortje Elisabeth Maria Van den Heuvel
The accurate estimation of precipitation quantities arriving at the ground in complex terrain such as the Alps is complicated by many factors. The orography interacts with atmospheric flow and thus influences the spatial and temporal distribution as well a ...
EPFL2019Spatial interpolation of precipitation from multiple rain gauge networks and weather radar data for operational applications in Alpine catchments
Giovanni De Cesare, Javier García Hernández, Bettina Schaefli, Alain Tommy Foehn
Increasing meteorological data availability and quality implies an adaptation of the interpolation methods for data combination. In this paper, we propose a new method to efficiently combine weather radar data with data from two heated rain gauge networks ...
2018From the Clouds to the Ground - Snow Precipitation Patterns in Complex Terrain
Varun Sharma, Michael Lehning, Alexis Berne, Franziska Gerber, Marco Gabella, Nikola Besic, Urs Martin Germann
Snow accumulation patterns are determined by many different processes from ice crystal nucleation in clouds to snow redistribution by wind and avalanches. In between, snow precipitation undergoes different dynamical and microphysical processes, such as ice ...
2018High-Resolution Simulation Study Exploring the Potential of Radars, Crowdsourced Personal Weather Stations, and Commercial Microwave Links to Monitor Small-Scale Urban Rainfall
Alexis Berne, Timothy Hugh Raupach
Many applications in urban areas require high-resolution rainfall measurements. Typical operational weather radars can provide rainfall intensities at 1-km(2) grid cells every 5min. Opportunistic sensing with commercial microwave links yields path-averaged ...
AMER GEOPHYSICAL UNION2018Spatial variability in snow precipitation and accumulation in COSMO–WRF simulations and radar estimations over complex terrain
Varun Sharma, Michael Lehning, Alexis Berne, Franziska Gerber, Marco Gabella, Nikola Besic, Urs Martin Germann
Snow distribution in complex alpine terrain and its evolution in the future climate is important in a variety of applications including hydropower, avalanche forecasting and freshwater resources. However, it is still challenging to quantitatively forecast ...
2018Precipitation at Dumont d'Urville, Adelie Land, East Antarctica: the APRES3 field campaigns dataset
Alexis Berne, Jacopo Grazioli, Christophe Praz
Compared to the other continents and lands, Antarctica suffers from a severe shortage of in situ observations of precipitation. APRES3 (Antarctic Precipitation, Remote Sensing from Surface and Space) is a program dedicated to improving the observation of A ...
COPERNICUS GESELLSCHAFT MBH2018A high space-time resolution dataset linking meteorological forcing and hydro-sedimentary response in a mesoscale Mediterranean catchment (Auzon) of the Ardeche region, France
Alexis Berne, Jacopo Grazioli, Timothy Hugh Raupach
A comprehensive hydrometeorological dataset is presented spanning the period 1 January 201131 December 2014 to improve the understanding of the hydrological processes leading to flash floods and the relation between rainfall, runoff, erosion and sediment t ...
Copernicus GmbH2017Improving local wind estimation for the automated control of blinds
Jean-Louis Scartezzini, Dasaraden Mauree, Laurent Deschamps, Ali Motamed
Blinds are usually installed on building façade to improve the visual and thermal comfort of the oc-cupants. They are now often linked to an automat-ed system that helps control the glare and decrease overheating. These automated systems are linked to a we ...
2017Multiregional Satellite Precipitation Products Evaluation over Complex Terrain
An extensive evaluation of nine global-scale high-resolution satellite-based rainfall (SBR) products is performed using aminimumof 6 years (within the period of 2000-13) of reference rainfall data derived from rain gauge networks in nine mountainous region ...
American Meteorological Society2016Variability of the raindrop size distribution across scales in Mediterranean rainfall
Measurement of rain is made difficult by the high variability of the precipitation process, down to raindrop scale. Point measurements are generally accurate, but their lack of spatial representativeness is a significant limitation. Weather radars indirect ...
