Mast observations
This API provides mast-based weather observations from three measurement masts operated by the Finnish Meteorological Institute. Data includes temperature, relative humidity, and wind measurements recorded at multiple heights along each mast, ranging from 2 metres to 327 metres depending on the site. The dataset offers a vertical profile of atmospheric conditions, useful for studying how weather variables change with altitude near the surface. Coverage is national, focused on Finland, and access is free without authentication.The data includes temperature, relative humidity and wind observations from the three mast measurement sites of the Finnish Meteorological Institute. These observations range from 2 metres to 327 metres, depending on the mast site.
