June update (1.6.2023)
Fixed two faulty WFS stored queries:
ecmwf::forecast::surface::grid
ecmwf::forecast::surface::finland::grid
Change deprecated Hirlam-datasource to correct ECMWF-datasource.
Update default parameter list in both queries to contain all parameters that are available in the data: Temperature, Pressure, Humidity, GeopHeight, WindUMS, WindVMS, Precipitation1h, GroundTemperature.

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.
