Deployment and Performance Analyses of High-Resolution Iowa XPOL Radar System during the NASA IFloodS Campaign

Jacopo Grazioli

This article presents the data collected and analyzed using the University of Iowa's X-band polarimetric (XPOL) radars that were part of the spring 2013 hydrology-oriented Iowa Flood Studies (IFloodS) field campaign, sponsored by NASA's Global Precipitatio ...

Hydrometeor classification using clustering of polarimetric radar measurements

Alexis Berne, Devis Tuia, Jacopo Grazioli

LMA observations of upward lightning flashes at the Santis Tower initiated by nearby lightning activity

Farhad Rachidi-Haeri, Marcos Rubinstein, Mohammad Azadifar, Antonio Sunjerga, Amirhossein Mostajabi, Jacopo Grazioli, Nikola Besic

We present in this paper lightning current measurements, LMA (Lightning Mapping Array) data and fast antenna electric fields associated with upward flashes observed at the Santis Tower during summer of 2017. The LMA network consists of six stations that we ...

Observation of the Orientation of Snow Hydrometeors at Sheltered and Unsheltered Sites

Alexis Berne, Jacopo Grazioli

Knowledge about orientation of falling snow is still poorly documented with field measurements despite its importance, for example, in the interpretation of remote sensing data. This study investigates the orientation of snow hydrometeors using data from a ...

Reconstruction of the mass and geometry of snowfall particles from multi-angle snowflake camera (MASC) images

Alexis Berne, Jacopo Grazioli, Jussi Sakari Leinonen

This paper presents a method named 3D-GAN, based on a generative adversarial network (GAN), to retrieve the total mass, 3D structure and the internal mass distribution of snowflakes. The method uses as input a triplet of binary silhouettes of particles, co ...

Evaluation of the CloudSat surface snowfall product over Antarctica using ground-based precipitation radars

Alexis Berne, Jacopo Grazioli

In situ observations of snowfall over the Antarctic Ice Sheet are scarce. Currently, continent-wide assessments of snowfall are limited to information from the Cloud Profiling Radar on board the CloudSat satellite, which has not been evaluated up to now. I ...

Unraveling hydrometeor mixtures in polarimetric radar measurements

Alexis Berne, Jacopo Grazioli, Nikola Besic, Marco Gabella, Josué Etienne Gehring, Christophe Praz

Radar-based hydrometeor classification typically comes down to determining the dominant type of hydrometeor populating a given radar sampling volume. In this paper we address the subsequent problem of inferring the secondary hydrometeor types present in a ...

INTEGRATING SUSTAINABILITY IN HIGHER EDUCATION INSTITUTIONS: A CASE STUDY FROM EPFL

Siroune Marie-Noëlle Der Sarkissian, Pierre Dillenbourg, Françoise Gisou van der Goot Grunberg, Jacopo Grazioli, Vittorio Rossi, Adélie Eliane Garin

As concerns regarding sustainability and ethical responsibility in engineering practices continue to rise, it becomes imperative for Higher Education Institutions (HEIs) to equip future engineers with the necessary knowledge and skills to address these cha ...

Katabatic winds diminish precipitation contribution to the Antarctic ice mass balance

Alexis Berne, Jacopo Grazioli

Snowfall in Antarctica is a key term of the ice sheet mass budget that influences the sea level at global scale. Over the continental margins, persistent katabatic winds blow all year long and supply the lower troposphere with unsaturated air. We show that ...
