Aerosol and meteorological data from a tethered balloon during the Villum campaign Mar-May 2024 at Villum Research Station, Greenland

The dataset introduced here originated from a field deployment with a tethered balloon, the EERL Helikite, at Villum Research Station in Northern Greenland. The measurements focused on aerosol and meteorological measurements along the vertical axis. 57 Helikite flights spread during the transition between Winter and Spring (23 March - 2 May 2024) provided aerosol number size distributions from 8 nm to 3370 nm, thermodynamic and dynamic parameters, and aerosol light absorption. All the variables were time synchronized, quality controlled, and corrected by Standard Temperature and Pressure (STP) when necessary. Measurements included: particle number size distributions between 186 and 3370 nm measured with a Portable Optical Particle Spectrometer (POPS, Handix Scientific LLC, USA); particle number size distributions and total particle concentration between 8 and 300 nm measured by a miniaturised Scanning Electrical Mobility Sizer (mSEMS, model 9404, Brechtel Manufacturing Inc., USA) with a soft x-ray neutraliser (soft x-ray charger, XRC-05, HCTM Co., Ltd., South Korea), a differential mobility analyser (DMA) column and an advanced mixing condensation particle counter (amCPC, model 9403, Brechtel Manufacturing, In., USA);  wind direction and wind speed measurements from the SmartTether Weather Sonde (Anasphere, Inc); temperature and RH measurements by RH/T sensors (SHT85, Sensiron); and a single-channel tricolor absorption photometer (STAP, Brechtel Manufacturing Inc., USA) measured the aerosol light absorption at 450, 525, and 624 nm.
