Storm Ancestry Intelligence

See the atmospheric column without losing the weather.

SAI is AERI's live atmospheric column. It follows solar and upper-atmospheric signals through seven layers and shows what is active, what is unavailable, and what still sits outside the daily stack.

Clear claims, clear limits

SAI is an atmospheric research interface, not a replacement for weather forecasting. It observes correlations across multiple layers of the atmosphere and shows where the live data is active, unavailable, or still outside the daily stack.

The current daily issue uses live NOAA, NWS, CPC, and Oulu inputs plus a last-good issue fallback. It does not claim that solar forcing causes a specific storm. For life-safety decisions, follow NWS products exclusively.
