SponsorshipThis work was essentially supported by the Department of Energy (USA) under the project DE-SC0016541. The humidified nephelometer measurements at BRW and SGP were funded by the U.S. Department of Energy Atmospheric Radiation Measurement (DOE/ARM) program via Argonne National Laboratory. The DOE/ARM Program Climate Research Facility and the DOE Atmospheric Sciences Program funded the AMF deployments (FKB, GRW, HFE, MAO, NIM, PGH, PVC, PYE). Measurements at KCO were supported by the National Science Foundation (Grant ATM-961288). The CBG humidified nephelometer measurements were supported by the NOAA Climate Goal program. The HLM measurements were supported by DOE’s ASP program under grant DE-A102-05ER63996. The GSN measurements were supported by NSF grant 0138250. The humidified nephelometer measurements operated by the Paul Scherrer Institute (CES, JFJ, MEL, MHD, ZEP, and HYY) and the instrument development itself were financially supported by the projects ESA Climate Change Initiative Aerosol cci (ESRIN/Contract No. 4000101545/10/I-AM), the Swiss National Science Foundation (Advanced Postdoc.Mobility fellowship; Grant No. P300P2_147776), and by the EC-projects Global Earth Observation and Monitoring (GEOmon, contract 036677) and European Supersites for Atmospheric Atmospheric Aerosol Research (EUSAAR, contract 026140). The measurements of the University of Granada (UGR) were supported by the Spanish Agencia Estatal de Investigación, AEI, through projects CGL2016-81092-R and CGL2017-90884- REDT and the European Union’s Horizon 2020 research and innovation program through project ACTRIS-2 (Grant Agreement No. 654109). The Lin’an site observation was supported by the National Natural Science Foundation of China (41475118). We thank Markus Fiebig, Richard Olav Rud, and Paul Eckhardt (NILU, Norway) for their great help to prepare and submit the data files to the EBAS and ACTRIS data centre. Open access funding provided by Stockholm University.
A reference dataset of multi-wavelength particle light scattering and hemispheric backscattering coefficients for different relative humidities (RH) between RH = 30 and 95% and wavelengths between λ = 450 nm and 700 nm is described in this work. Tandem-humidified nephelometer measurements from 26 ground-based sites around the globe, covering multiple aerosol types, have been re-analysed and harmonized into a single dataset. The dataset includes multi-annual measurements from longterm monitoring sites as well as short-term field campaign data. The result is a unique collection of RH-dependent aerosol light scattering properties, presented as a function of size cut. This dataset is important for climate and atmospheric model-measurement inter-comparisons, as a means to improve model performance, and may be useful for satellite and remote sensing evaluation using surface-based, in-situ measurements.
