In-situ boundary-layer meteorological observations were made from the ice floe using sensors hanging under a tethered balloon which was quasi-continuously winched up and down in the ~0 – 1200 m layer.
There are three sensor packages: (1) Broadband radiation package: upward and downward irradiance in the solar and terrestrial wavelength range and standard meteorological measurements. (2) Standard Meteorological package: standard meteorological measurements including wind speed and direction. (3) Hot-wire package: standard meteorological measurements, wind speed, wind speed fluctuations and wind direction
Single profiles were performed in the period between August 18 2018 and September 13 2018 during the drift period of the campaign close to the North Pole. These vertical profiles provide a better insight into the vertical structure of the boundary layer (turbulence/stability) and the interaction of clouds and the surface.

Data description
10 Hz standard meteorological data and broadband irradiance (T, RH, p, q, SWD, SWU, LWD, LWU) and attitude data. An icing flag is included, which is derived from camera pictures available on request. Date processing carried out by Matthias Gottschalk. A single txt-file for each flight.
1 Hz standard meteorology data (T, RH, p, u, q). Data processing carried out by Ulrike Egerer. A single txt-file for each flight accompanied.
500 Hz hot-wire data and the standard meteorology (T, RH, p) are interpolated on the same range. The wind velocity is included with 10 Hz. Data processing carried out by Ulrike Egerer. A single txt-file for each flight.
