A Variational Approach to Retrieve Rain Rate by Combining Information from Rain Gauges, Radars, and Microwave Links

Alexis Berne, Blandine Bianchi

Accurate and reliable rain rate estimates are important for various hydrometeorological applications. Consequently, rain sensors of different types have been deployed in many regions. In this work, measurements from different instruments, namely, rain gaug ...

Assessing the potential of using telecommunication microwave links in urban drainage modelling

Marc Schleiss

The ability to predict the runoff response of an urban catchment to rainfall is crucial for managing drainage systems effectively and controlling discharges from urban areas. In this paper we assess the potential of commercial microwave links (MWL) to capt ...

Experimental Quantification of the Variability of the Raindrop Size Distribution at Small Scales

Joël Jaffrain

Reliable quantitative precipitation estimation is crucial to better understand and eventually prevent water-related natural hazards (floods, landslides, avalanches, ...). Because rainfall is highly variable in time and space, precipitation monitoring and f ...

Influence of the DSD variability at the radar subgrid scale on radar power laws

Alexis Berne, Joël Jaffrain

Power laws relating the different radar observables (from conventional or polarimetric radar systems) are commonly used in the processing of radar measurements (e.g., attenuation correction) and in their conversion into rain rate values (e.g., Z-R relation ...

Influence of the Subgrid Variability of the Raindrop Size Distribution on Radar Rainfall Estimators

Alexis Berne, Joël Jaffrain

This work aims at quantifying the variability of the parameters of the power laws used for rain-rate estimation from radar data, on the basis of raindrop size distribution measurements over a typical weather radar pixel. Power laws between the rain rate an ...

Stochastic space-time disaggregation of rainfall into DSD fields

Alexis Berne, Marc Schleiss

A stochastic method to disaggregate rainfall fields into DSD fields is proposed. It is based on a previously presented DSD simulator that has been modified in order to take into account imposed mean values provided at the coarser scale. The integral quanti ...

Variability of the Rain Drop Size Distribution

Marc Schleiss

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 ...

A network of disdrometers to quantify the small-scale variability of the raindrop size distribution

Alexis Berne, André Studzinski, Joël Jaffrain

Insight into the spatial variability of the (rain) drop size distribution (DSD), and hence rainfall, is of primary importance for various environmental applications like cloud/precipitation microphysical processes, numerical weather modeling, and estimatio ...

Statistical analysis of rainfall intermittency at small spatial and temporal scales

Alexis Berne, Marc Schleiss, Joël Jaffrain

Rainfall intermittency is analyzed and quantified at small spatial and temporal scales using 2 years of radar and disdrometer data collected in Switzerland. Analytical models are fitted and used to describe the intermittency for spatial scales between 0 an ...
