{"name":"Colorado Hail Aggregates","description":"Aggregate Colorado hail statistics compiled from NOAA NEXRAD radar, live MRMS, the NOAA Storm Events Database, SPC Local Storm Reports, and CoCoRaHS. All-time figures (total events, largest hail, biggest storms) span 1955 to the present; the by-year, by-month, and by-county breakdowns cover 2015 to the present. Aggregate counts only — no property-level or personal data.","license":"CC-BY-4.0","attribution":"HailScore (myhailscore.com).
