The tethered balloon system BELUGA (Balloon-bornE moduLar Utility for profilinG the lower Atmosphere) was operated at Villum research station in northern Greenland (81°34'54''N, 16°37'14''W, elevation 30m). The measurements were taken during the PAMARCMiP (Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project) campaign on 14 days in the period 21 March to 4 April 2018. For this campaign, a 9 m³ helium filled balloon with modular instrumentation was used. The dataset includes measurements of: - standard meteorological data based on a GRAW DFM-09 radiosonde with additional wind speed measurements by a Pitot-static probe - wind turbulence with a hot-wire anemometer (for instrument characteristics and methods see Egerer et al., 2019) - solar and terrestrial broadband radiation with upward and downward looking pyrgeometers and pyranometers (for instrument characteristics and methods see Egerer et al., 2019). The flights are summarized in the flight overview table (see "Further details"). Each flight includes measurements of standard meteorological data and in most cases of a second instrument.

In a new version of the meteorological data (see doi:10.1594/PANGAEA.933223), the wind speed calibration for the standard meteorology sonde has been revised. Therefore, for meteorology, please use the new version.
