Overfladeobservation

Overfladeobservation, also known as surface observation, refers to the systematic collection of meteorological data from the Earth's surface. These observations are critical for weather forecasting, climate monitoring, and research. Surface observations typically include measurements of temperature, humidity, atmospheric pressure, wind speed and direction, precipitation, and visibility. Instruments such as thermometers, hygrometers, barometers, anemometers, rain gauges, and ceilometers are commonly used to gather this data.

Surface observation stations can be automated or manually operated. Automated stations, often referred to as Automated Weather Stations (AWS), continuously record data and transmit it electronically to central databases. Manual stations, on the other hand, rely on human operators to record observations at scheduled intervals, usually every hour. Both types of stations adhere to standardized protocols to ensure consistency and comparability of data.

Overfladeobservation plays a vital role in various applications, including aviation safety, agriculture, and public warning systems for severe weather events. Meteorological services worldwide, such as the World Meteorological Organization (WMO), coordinate global observation networks to maintain comprehensive and reliable surface data. This data is essential for numerical weather prediction models, which simulate atmospheric conditions to forecast weather patterns. Additionally, long-term surface observation records are used to study climate trends and changes over time. The accuracy and timeliness of surface observations directly impact the reliability of weather forecasts and climate assessments.
