# Weather of Record

> Published government and volunteer weather records for a U.S. street address and date, with provenance for every value.  Records, not opinions: no response is a determination about any property.  The absence of a record is not evidence that an event did not occur.  Records reach back to about 1960.  A lookup runs in roughly two minutes: submit, then poll.
