    "abstract": "Recommendations are made for NASA/JAXA Global Precipitation Measurement (GPM)\nsatellite Ground Validation (GV) program. This report details recommended GV\nsite local radar products based on data from surface-based scanning radars\nincluding S-band, C-band, and X-band polarimetric and non-polarimetric radars.\nThree general categories of products are described: text products summarizing\ninformation on the statistical characteristics of the radar data and derived\nparameters, 2D products providing maps of the horizontal variability of near\nsurface radar observed and derived parameters, and 3D products describing\nvolumetric echo structure. Regional composites could include products based on\nseveral of the 2D and 3D single radar products. Several types of\ntime-integrated 2D and 3D products are also recommended. A brief discussion of\nuseful ancillary data from other sources and remaining challenges concludes the\nreport.",
