Snowfall microphysics: a dual-frequency and Doppler spectral radar perspective
Anne-Claire Marie Billault--Roux
Snowfall is an essential component of the hydrological cycle, as it is involved in most precipitation on Earth, either directly as snow falling to the ground or indirectly as rain melted from snow. At the same time, the ice phase of clouds and precipitatio ...
EPFL2023Complex-Valued-Autoencoder for Structural Health Monitoring with Frequency Modulated Continuous Wave Radar
Olga Fink, Gaëtan Michel Frusque
The occurrence of manufacturing defects in wind turbine blade (WTB) production can result in significant increases in operation and maintenance costs of WTBs, reduce capacity factors of wind farms, and occasionally lead to severe and disastrous consequence ...
Research Publishing2023Dual-frequency spectral radar retrieval of snowfall microphysics: a physics-driven deep-learning approach
The use of meteorological radars to study snowfall microphysical properties and processes is well established, in particular via a few distinct techniques: the use of radar polarimetry, of multi-frequency radar measurements, and of the radar Doppler spectr ...
COPERNICUS GESELLSCHAFT MBH2023A Characterisation of Alpine Mesocyclone Occurrence
Alexis Berne, Marco Gabella, Monika Feldmann, Urs Martin Germann
This work presents a characterisation of mesocyclone occurrence and frequency in the Alpine region, as observed from the Swiss operational radar network; 5 years of radar data are processed with a thunderstorm detection and tracking algorithm and subsequen ...
2021A 60 GHz QDCO with 11 GHz Seamless Tuning for Low-Power FMCW Radars in 22-nm FDSOI
Christian Enz, Francesco Chicco, Sammy Cerida Rengifo
This paper presents the design of a 60GHz Quadrature Digitally-Controlled Oscillator for a low-power Frequency-Modulated Continuous Wave radar System-on-Chip. The accurate detection of vital signs requires 1 and Q demodulation of the received signal. The q ...
IEEE2021Microphysics and dynamics of snowfall associated with a warm conveyor belt over Korea
Alexis Berne, Josué Etienne Gehring, Nikola Besic, Etienne Gabriel Henri Vignon, Nicolas Jean François Jullien
On 28 February 2018, 57mm of precipitation associated with a warm conveyor belt (WCB) fell within 21 h over South Korea. To investigate how the large-scale circulation influenced the microphysics of this intense precipitation event, we used radar measureme ...
