Data License

How the storm datasets published on StormAuditor pages may be used and cited.

What this license covers

This page is the license reference for the aggregated storm datasets published on StormAuditor's state and city storm-history pages — the deduplicated event counts, biggest-storm-day lists, and county totals derived from public weather records.

Underlying public records

The underlying source records — NOAA and National Weather Service warnings, Local Storm Reports, ASOS/AWOS station observations, MRMS radar products, URMA analyses, NCEI Storm Events, and FEMA declarations — are U.S. government works in the public domain. They are listed with links on the data sources page and can always be obtained directly from the agencies.

Reusing StormAuditor's aggregations

StormAuditor's deduplicated aggregations, derived statistics, and page content may be quoted, reused, and linked free of charge — in blogs and marketing, research, journalism, academic work, and claim documentation — including by AI assistants and writing tools. No permission or credit is required; a link to the page the data came from is welcome, since it gives readers the full context and latest numbers. Values are estimates produced under the published methodology — cite them as estimates, not as certified weather records. Crawling, AI answers, and AI training on these public pages are welcome; republishing the datasets wholesale as a competing database is not permitted; the Terms of Service govern use of the site.
