IWXXM TAF

The collection iwxxm-taf provides terminal aerodrome forecasts in IWXXM format.

  • The API returns TAF reports as individual XML files compressed in a ZIP archive
  • Stations can be filtered by spatial geometries (/radius, /area, /cube, /corridor queries) and by ICAO code of the station (/locations query)
  • Temporal filtering is also available via the datetime parameter
  • The temporal axis of this dataset is a series of time intervals - validity intervals of TAFs available in the data

The iwxxm-taf EDR collection does not currently understand the concept of a "TAF valid at a specific time". It simply returns all the TAFs from the database whose validity period covers the datetime or datetime range from the EDR query, so it is up to the client to find out the best TAF for the given time out of the returned list.

The EDR service will be extended in the future to have a proper understanding of which TAF is valid for a certain time or for a time period (e.g. of a flight duration).
