Description
Summary:During the MOSAiC-ACA campaign conducted in August/September 2020 in Svalbard meteorological data (temperature, 3 wind components, air pressure) have been measured in high temporal resolution (100 Hz) using instrumentation that was installed at the nosebooms of Polar 5. For each flight the data are given as functions of time and position (including height above ground) along the flight tracks. All flights started and ended in Longyearbyen, Svalbard. Each file represents an entire flight starting well before the first movement of the plane and ending after the final parking position has been reached after landing. The wind measurement is only valid during flight and the full accuracy is only achieved during straight level flight sections. The absolute accuracy of the wind components is 0.2m/s for straight and level flights sections and the relative accuracy of the vertical wind speed is about 0.05m/s for straight and level flight sections. For these sections, which can be obtained on the basis of the given ... : t - UTC-time in seconds (since midnight)lon - longitude in degress based on WGS84lat - latitude in degress based on WGS84h - height in metres based on WGS84p - static pressure in hpa, corrected for the influence of the aircraftT - temperature from PT100, corrected for adiabatic heatingu - west-east component of wind speed in m/s, positive towards eastv - south-north component of wind speed in m/s, positive towards northw - vertical wind speed in m/spitch - pitch angle in degreesroll - roll angle in degreesthdg - true heading of the aircraft in degrees ...
