Quantification of the Small-Scale Spatial Structure of the Raindrop Size Distribution from a Network of Disdrometers

The spatial structure of the raindrop size distribution (DSD) conveys crucial information for reliable quantitative estimation of rainfall using remote sensing techniques. To investigate this question, a network of 16 optical disdrometers has been deployed ...

Relatedness and scale dependency in very high resolution digital elevation models derivatives

Stéphane Joost, Kevin Leempoel

In the field of landscape genetics, environmental variables are needed to assess the influence of the environment on the spatial distribution of the genetic information of animals or plants. However, measuring variables (e.g. temperature, precipitation) at ...

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 ...

Building Virtual Earth Observatories Using Ontologies, Linked Geospatial Data and Knowledge Discovery Algorithms

Manolis Karpathiotakis

Advances in remote sensing technologies have allowed us to send an ever-increasing number of satellites in orbit around Earth. As a result, satellite image archives have been constantly increasing in size in the last few years (now reaching petabyte sizes) ...

Implementation of dust emission and chemistry into the Community Multiscale Air Quality modeling system and initial application to an Asian dust storm episode

Yi Zhang, Athanasios Nenes

The US Environmental Protection Agency's (EPA) Community Multiscale Air Quality (CMAQ) modeling system version 4.7 is further developed to enhance its capability in simulating the photochemical cycles in the presence of dust particles. The new model treatm ...

Vidy Bay hydrodynamics under typical meteorological conditions

David Andrew Barry, Ulrich Lemmin, Amir Mehdi Razmi

Vidy Bay (Lake Geneva, Switzerland) is the site of a sewage outfall, located 700 meters offshore at a depth of 30 meters. Estimates of water circulation in this area are required to assess the transport and fate of water quality components. Numerical simul ...

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 ...

Pollution transport efficiency toward the Arctic: Sensitivity to aerosol scavenging and source regions

Isabelle Bey, Quentin Bourgeois

The processes driving current changes in Arctic atmospheric composition and climate are still uncertain. In particular the relative contributions of major source regions from the midlatitudes remain a matter of debate in the literature. The objectives of t ...

Integrating the impact of rain into traffic management: online traffic state estimation using sequential Monte Carlo techniques

This paper consists in a new step toward the integration of the effects of inclement weather into traffic management strategies. It is well recognized that adverse weather conditions are a critical factor impacting traffic operations and safety. In a previ ...

Estimation of urban sensible heat flux using a dense wireless network of observations

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Olivier Couach, Marc-Olivier Boldi

The determination of the sensible heat flux over urban terrain is challenging due to irregular surface geometry and surface types. To address this, in 2006–07, a major field campaign (LUCE) took place at the École Polytechnique Fédérale de Lausanne campus, ...
