FMI Open data WFS services

FMI Open Data WFS service implements the Simple WFS conformance class of the WFS 2.0 specification. The service uses stored queries extensively to select features, areas and times. Stored queries are named and parametrized queries to be used with GetFeature operation.

Aviation weather observation reports will be removed from open data distribution by the end of 2024

The Finnish Meteorological Institute provides observation services at Finnish airports and is responsible for the development and maintenance of systems in accordance with the evolving needs of users. Aviation weather observations are transmitted to airspace users as so-called METAR reports every thirty minutes for international distribution.

Since 2013, aviation weather observations and reports have been part of the Finnish Meteorological Institute's open data distribution, and they have been produced using the institute's operational funding. The Finnish Meteorological Institute openly shares near real-time observation data from airports as well as aviation weather reports.

The government’s cuts to the Ministry of Transport and Communications' operating budget, starting in 2025, will affect the operations of the Finnish Meteorological Institute and also the open data distribution. The costs incurred from the production of aviation weather observations will, in the future, be borne by airspace users. In accordance with aviation principles, observations that are entirely funded by airspace users cannot be openly shared among all users.

From 2025 onwards, aviation weather reports will be available to users in the same way as before through aviation information systems, but no longer through the open data interfaces of the Finnish Meteorological Institute.
