Säähavainnointijärjestelmä

Säähavainnoint, or weather observation, is the systematic collection of meteorological data. These observations are crucial for understanding atmospheric conditions, predicting future weather patterns, and providing vital information for a wide range of activities.

Observations are typically made at regular intervals and can include measurements of temperature, humidity, atmospheric pressure, wind speed and direction, precipitation, and cloud cover. Specialized instruments such as thermometers, hygrometers, barometers, anemometers, and rain gauges are used for this purpose. More advanced technologies, including weather balloons, radar, and satellites, provide data over larger areas and at different altitudes.

Weather observations are fundamental to the science of meteorology. They form the basis for weather forecasting models, which are used by national weather services and private companies to issue forecasts for public safety, aviation, agriculture, and maritime operations. Beyond forecasting, historical weather data is also important for climate research, allowing scientists to track long-term trends and understand climate change.

Säähavainnoint is conducted by a variety of entities, including official meteorological agencies, research institutions, and increasingly, citizen scientists who contribute data from personal weather stations. The standardization of observation methods and data reporting ensures that observations from different locations and times can be compared and integrated effectively. This collaborative effort underpins our global understanding of the Earth's atmosphere.
