The representation of orographic clouds in numerical weather prediction models remains a great challenge, as a consequence of our incomplete understanding of the microphysical processes acting on them and the complex interactions between the large-sc

Dual-frequency spectral radar retrieval of snowfall microphysics: a deep-learning based approach

Autor: Anne-Claire Billault–Roux, Gionata Ghiggi, Alexis Berne

Publikováno v: XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)

Better understanding snowfall microphysics is a key challenge in atmospheric science, crucial for snowfall quantification, remote sensing, and weather forecasting in general.Using meteorological radars, we propose a novel approach to retrieve the mic

The use of meteorological radars to study snowfall microphysical properties and processes is well established, in particular through two techniques: the use of multi-frequency radar measurements and the analysis of radar Doppler spectra. We propose a
