By default, the data is returned from last 12 hour. At least one location parameter (geoid/place/fmisid/wmo/bbox) has to be given. The data is returned as a multi point coverage format. Parameter begin specifies the begin of time interval in ISO-format (for example 2012-02-27T00:00:00Z). End of time interval in ISO-format (for example 2012-02-27T00:00:00Z). The time step of data in minutes. Notice that timestep is calculated from start of the ongoing hour or day. Comma separated list of meteorological parameters to return. Coordinate projection to use in results. For example EPSG::3067 Bounding box of area for which to return data (lon,lat,lon,lat). For example 21,61,22,62 The location for which to provide data. Region can be given after location name separated by comma (for example Kumpula,Kolari). Identifier of the observation station. How many observation stations are fetched around queried locations. Note that stations are only searched with 50 kilometers radius around the location. Geoid of the location for which to return data. (ID from geonames.org) WMO code of the location for which to return data.
