# D-ATIS Fast Lane

> Pro-only METAR-equivalent weather extracted from FAA D-ATIS broadcasts, usually available minutes before the official METAR.

`metar.atis.<icao>` carries METAR-equivalent weather extracted from FAA D-ATIS broadcasts for 12 major US hubs. It is available on the Pro plan only; subscribing with a Starter key returns `permission_denied`.

## Why it's faster

D-ATIS data usually lands about one minute after the observation time, several minutes ahead of the official METAR mirrors that populate `metar.obs.*`.

## Things to know before you subscribe

<AccordionGroup>
  <Accordion title="raw is reconstructed, not original">
    The `raw` field is rebuilt from the ATIS text rather than being the official METAR string. The decoded values match the official report, but the exact formatting may differ.
  </Accordion>

  <Accordion title="The same observation appears twice">
    The same observation later appears on the station's `metar.obs.<icao>` channel with the official text. If you subscribe to both channels, deduplicate by the pair (`station`, `report_time`).
  </Accordion>

  <Accordion title="Only genuinely new observations are published">
    ATIS re-broadcasts, information-letter changes, and runway or NOTAM-only updates never produce a new event; only observations proven to be new are published.
