I parametri meteorologici (temperatura dell’aria, pressione atmosferica, umidità relativa, precipitazione, velocità e direzione del vento) sono misurati con una stazione meteorologica automatica Vaisala WXT520. Meteorological parameters (air-temperature, atmospheric pressure, relative humidity, rain precipitation, wind speed and direction) are measured by an automatic weather station (Vaisala WXT520). Technical details: Wind Speed (range: 0 - 60 m/s, response time: 250 ms, accuracy (0 - 35 m/s): ±0.3 m/s or ±3%, accuracy (35 - 60 m/s): ±5%; output resolutions: 0.1 m/s) units 0.1 mph, 0.1 knots Wind Direction (response time: 250 ms; accuracy ±3°; output resolution and unit 1°) Rainfall (output resolutions and units 0.01 mm, accuracy: 5%, Due to the nature of the phenomenon, deviations caused by spatial variations may exist in precipitation readings, specially in a short time scale. The accuracy specification does not include possible wind induced errors) Relative Humidity (Range: 0 - 100 %RH; Accuracy (0-90%): ±3 %. accuracu (90-100%):±5, output resolution and unit 0.1 %R) Barometric Pressure (Range: 600 - 1100 hPa; Accuracy (0 - +30 °C): ±0.5 hPa, accuracy (-52 - +60 °C ): ±1 hPa, Output resolutions and units: 0.1 hPa) Air Temperature (Range: -52 - +60 °C; Accuracy for sensor at +20 °C: ±0.3 °C)
