Our data
Four independent data sources, blended and reviewed by named meteorologists. 25 years of archive. A methodology published, peer-referenced, and repeatedly stress-tested in federal court.
Level II/III radar sweeps for every storm in our archive, processed with Cotality-proprietary algorithms that correct for beam broadening, ground clutter, and hail-size overestimation.
Station-level wind gust, temperature, and precipitation readings, interpolated to the parcel with documented uncertainty bounds.
Verified ground-truth observations — spotter reports, insurance-claim geolocation, photographic evidence — collected from NWS and SPC databases.
Every Forensic-tier report is reviewed and signed by a senior meteorologist. Forensic Plus adds a sworn affidavit and named-expert credentials.
