1Hz resolution aircraft measurements of wind and temperature during the ACLOUD campaign in 2017


During the ACLOUD (Arctic Cloud Observations Using airborne measurements during polar Day) campaign conducted in May/June 2017 meteorological data (temperature, horizontal wind components, air pressure) have been measured using instrumentation that was installed at the nosebooms of both aircraft Polar 5 and Polar 6. This dataset presents the 1Hz resolution data. The high temporal resolution data (at 100 Hz) with all wind components are available here: doi:10.1594/PANGAEA.900880).For each flight the data are given as functions of time and position (including height above ground) along the flight tracks. Listed in this repository are all flights beginning with the test flight in Bremen and the Ferryflights to Longyearbyen. All other measurement flights started and ended in Longyearbyen. 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. For further informations on the data processing and accuracy of the turbulence measurement refer to Hartmann et al. (2018, doi:10.5194/amt-11-4567-2018). For further information on the ACLOUD campaign we refer to Wendisch et al. (2018, doi:10.1175/BAMS-D-18-0072.1). --All data are given as decimal values at 1Hz in columns in this order and meaning: UTC - UTC-time in seconds (since midnight)h - height in metres based on WGS84lon - longitude in degress based on WS84lat - latitude in degress based on WS84p - static pressure in hpags - ground speed in m/s pitch - pitch angle in degreesroll - roll angle in degreesrh - relative humidity from Vaisala at noseboomT - temperature from PT100, corrected for adiabatic heating u - west-east component of wind speed in m/s, positive towards eastv - south-north component of wind speed in m/s, positive towards northtas - true air speed in m/s
