Aerosol and meteorological data from a tethered balloon during the CHOPIN (Mt Helmos) campaign Oct-Nov 2024 at Mt Helmos, Greece

This dataset contains vertical profile measurements from a tethered balloon platform including the following: equivalent Black Carbon concentrations and calculated aerosol light absorption coefficients at 375m 450, 528, 625 and 880 nm measured with a micro Aethalometer (mAeth, MA200, Aethlabs); 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); CO2 mixing ratio (Vaisala CARBOCAP Carbon Dioxide Probe GMP343, Vaisala, Finland); wind direction and wind speed measurements from the SmartTether Weather Sonde (Anasphere, Inc) and temperature and RH measurements by RH/T sensors (SHT85, Sensiron). Measurements were carried out at the Kalavryta Ski Resort at the base of Mt Helmos in Greece (38.004932°N, 22.198271°E, 1700 m above sea level) during the CHOPIN campaign within the CleanCloud project in Oct-Nov 2024.
