METARderived

METARderived is a term that refers to information or data that has been extracted or calculated from METAR (Meteorological Aerodrome Report) reports. METARs are standardized coded messages used by aviation to report weather conditions at airports. These reports contain a wealth of information including wind direction and speed, visibility, weather phenomena, cloud cover, temperature, and dew point.

When data is METARderived, it means that analysis has been performed on these METAR observations. This could involve extracting specific parameters for use in weather models, creating historical weather summaries, or identifying trends in atmospheric conditions. For example, a meteorological service might METARderive the average wind speed at a particular airport over a year to assess its suitability for wind energy projects. Similarly, researchers might METARderive the frequency of fog events from METAR data to study its impact on aviation safety.

The process of METARderived data generation often involves parsing the complex METAR code, interpreting each component, and then aggregating or transforming this information into a more usable format. Software applications are commonly used for this purpose to handle the large volumes of METAR data generated globally. The reliability of METARderived information is directly dependent on the accuracy and completeness of the original METAR reports.
