Data sets made available

The data sets are made available in machine-readable, digital format. Most of the data sets are already published. Rest of the data sets will be shared in phases as soon as it is technically ready for publishing. The Finnish Meteorological Institute also distributes the road weather observations of the Finnish Transport Infrastructure Agency, the radiation measurements of the Radiation and Nuclear Safety Authority and air quality observations from Finnish municipalities.

The Finnish Meteorological Institute share the following data

The data sets to be made available can be divided into three types: real-time observations, time series and forecasts. List of all Open data (in Finnish).

Real-time observations

This category contains continuously made observations that are used for monitoring the state or properties of the atmosphere and the Baltic Sea. Measurements are made mostly at observation stations more often than ones a day.

Wave and other observations from buoys
Sea level observations
Weather observations
Sun radiation observations
Lightning strikes
Radar images
Air quality observations
Upper-air sounding observations: ascending and descending.

Time series of observations

The category contains calculated values from the measurements and observations made at observation stations. The values calculated can be mean or extreme values of day, month or longer period.

Station specific daily and monthly values
Values of 30-year normal periods

Forecast and forecast models

The category contains forecast data from weather, sea, and air quality models that gives information about the future state of the atmosphere and the Baltic Sea. The output of a forecast model is usually grid like data. New forecast is commonly produced for a model more often than ones a day.

Weather forecast models HARMONIE and ECMWF
Meteorologist's weather forecast
Air quality forecast models SILAM and FMI-ENFUSER
Sea models: waves, currents (NEMO), sea surface temperature and sea ice (HELMI)
Sea level model for predefined points (NEMO)
Climate change forecasts for the 30-year periods 2010 - 2039, 2040 - 2069 and 2070 - 2099.

Operative observation stations

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.
