Multifrequency radar observations collected in southern France during HyMeX-SOP1.==$Bulletin of the American Meteorological Society, 96$==(2), 267-282. https://doi.org/10.1175/BAMS-D-13-00076.1index-oti2018http://hdl.handle.net/20.500.12816/2896The radar network deployed in southern France during the first special observing period (SOP 1) of the Hydrological Cycle in the Mediterranean Experiment (HyMeX) was designed to precisely document the 3D structure of moist upstream flow impinging on complex terrain as a function of time, height, and along-barrier distance, and surface rainfall patterns associated with orographic precipitation events. This deployment represents one of the most ambitious field experiments yet, endeavoring to collect high-quality observations of thunderstorms and precipitation systems developing over and in the vicinity of a major mountain chain. Radar observations collected during HyMeX represent a valuable, and potentially unique, dataset that will be used to improve our knowledge of physical processes at play within coastal orographic heavy precipitating systems and to develop, and evaluate, novel radar-based products for research and operational activities. This article provides a concise description of this radar network and discusses innovative research ideas based upon preliminary analyses of radar observations collected during this field project with emphasis on the synergetic use of dual-polarimetric radar measurements collected at multiple frequencies.application/pdfenginfo:eu-repo/semantics/openAccessRaindropMeteorological RadarDrop Sizeinfo:eu-repo/semantics/articlehttp://purl.org/pe-repo/ocde/ford#1.05.01Bulletin of the American Meteorological Societyhttps://doi.org/10.1175/BAMS-D-13-00076.1
