säähavaintokedon

Säähavaintokedon is a Finnish term used in meteorology to refer to the coded representation of weather observations. It denotes the conventions and schemes by which raw observational data—such as air temperature, humidity, wind direction and speed, precipitation, cloud cover, visibility, and atmospheric pressure—are converted into compact codes for transmission, storage, and computational processing. In practice, säähavaintokedon is aligned with international meteorological coding standards managed by the World Meteorological Organization, including formats like SYNOP and METAR, which Finnish agencies adapt for local use and language. The Finnish Meteorological Institute (FMI) and other data providers typically implement these codes within observation networks, forecasting models, and archives, enabling interoperable data exchange with international partners.

The word appears to be a compound of säähavainto (weather observation) and koodi (code), with the genitive ending -n, and is used in Finnish technical literature and training materials to denote an encoded weather dataset or the coding process itself. It is not a single official standard, but a term describing a general concept of weather observation coding.
