Avoin data muutosloki

Updates to open data in reverse chronological order (newest first)

April update (15.4.2021)

Time series of observations and forecasts

  • A new HTTP-interface available for meteorological time series. The interface is available for both observations and forecasts. History data is available for the last seven (7) days of the past. The interface has been originally planned for internal use within FMI and does not follow any external standard. The interface is useful for web applications and provides data in a variety of formats. For more information, see SmartMet plugin TimeSeries. Please note that the open data help desk may not be able to support you in your questions about the time series interface.

Drop sonde measurements

  • Added drop sonde measurements for air temperature (TAP_PT1S_AVG, one second average measure), relative humidity (RHP_PT1S_AVG, one second average measure) and air pressure (PAP_PT1S_AVG, one second average measure) for sonde flights in Finland. The query that can be used to get the results is fmi::observations::weather::dropsonde::multipointcoverage.

CTD (Conductivity, Temperature, Depth) measurements

  • Added CTD measurements from Finnish CTD devices. Available parameters are water temperature (TWP_PT1S_AVG, one second average measure), speed of sound (SVELP_PT1S_AVG, one second average measure), salinity (WSALP_PT1S_AVG, one second average measure), conductivity (WCONP_PT1S_AVG, one second average measure) , density (WSIGP_PT1S, one secong average measure), and the oxygen concentration (WO2P_PT1S_AVG, in units of ml/l, one second average measure and WO2PCTP_PT1S_AVG, in percentage, one second average measure) as a function of water pressure (WPREP_PT1S_AVG, one second average measure, corresponding approximately to depth). The following stored queries are available:

    • fmi::observations::ctd::simple

    • fmi::observations::ctd::timevaluepair

    • fmi::observations::ctd::multipointcoverage

March update (9.3.2021)

API key no longer required

Our open data is now more easily available without an API key. Registered users should switch over to the new address by the end of 2019 in order to use the service. Addresses that include the API key of the Finnish Meteorological Institute will no longer be operational after end of 2019.

June update (4.6.2019)
