Online in-situ atmospheric data for: A Decadal-Scale Perspective on PM10 Composition and its Variability Drivers at the Alpine High-Altitude Research Station Jungfraujoch

This dataset contains atmospheric parameters measured online in-situ at the High Altitude Research Station Jungfraujoch (JFJ, 3580 m above sea level, 46°32′ N 7°59′ E), between 2011 and 2021, as used in the manuscript Weng et al. (in preparation). Unless otherwise stated, data was aggregated from high time resolution data to time periods corresponding to the chemically analyzed composite filter samples in Weng et al. (in preparation) (per each sample, four 24 h filters at an interval of four days for the full period of 2011 to 2021). Periods identified as Saharan dust dominated (cf. Weng et al. (in preparation), SI) were omitted from the data. All mass concentrations are in $μg/m^3$. All mixing ratios are in $ppb$. Detailed descriptions of the data, methods, instruments (including data coverage periods) and results can be found in the manuscript.

The continuous online in-situ aerosol measurements at the JFJ receive financial support from MeteoSwiss in the frameworkof the Swiss contribution (GAW-CH) to the Global Atmosphere Watch program of the World Meteorological Organization(WMO), and from the Swiss State Secretariat for Education, Research and Innovation (SERI) in the framework of the Swisscontribution ACTRIS-CH to the ACTRIS ERIC. Measurements conducted by Empa are part of the Swiss National Air PollutionMonitoring Network (NABEL) which is jointly run by Empa and the Swiss Federal Office for the Environment (FOEN). VOC and NOx measurements are additionally supported through ACTRIS-CH and of CLIMGAS-CH. The 222Rn observations are supported by the Swiss National Science Foundation (SNSF) as a contribution to the pan-European Integrated Carbon Observation System (ICOS) (grant 20FI-0_229655).
