The French weather radar network ARAMIS operated by Meteo-France consists of 24 magnetron-based, C- and S-band radars. After several years of research and development, all radars were converted to Doppler radars and some are now polarimetric. These technological evolutions have resulted in improved weather radar measurements and have stimulated research in radar techniques for meteorological and hydrological applications.
In this seminar, I will present some of the latest techniques developed for the French weather radar network. First, I will give an overview of the current state of the network. Then, I will show results on the 3D velocity vector retrieval, polarimetric measurements, and refractivity estimation with magnetron radars. I will introduce Meteo-France’s 3D reflectivity data merging technique to integrate measurements from multiple radars and improve rainfall accumulation estimates that was developed in collaboration with the Joseph Fourier University in Grenoble. Finally, I will discuss a novel technique to mitigate range and velocity ambiguities for the ARAMIS radar network.
