Abstract:
During the ACLOUD (Arctic Cloud Observations Using airborne measurements during polar Day) campaign conducted in May/June 2017 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 both aircraft Polar 5 and Polar 6. 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 roll and pitch angles of the aircraft, the 100 Hz data can be used to derive turbulent fluxes of momentum and sensible heat. 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 100Hz in columns in this order and meaning:
t - UTC-time in seconds (since midnight)
lon - longitude in degress based on WGS84
lat - latitude in degress based on WGS84
h - height in metres based on WGS84
p - static pressure in hpa, corrected for the influence of the aircraft
T - temperature from PT100, corrected for adiabatic heating
u - west-east component of wind speed in m/s, positive towards east
v - south-north component of wind speed in m/s, positive towards north
w - vertical wind speed in m/s
pitch - pitch angle in degrees
roll - roll angle in degrees
thdg - true heading of the aircraft in degrees
