Harmonized aerosol size distribution, cloud condensation nuclei, chemistry and optical properties at 12 sites

There are 6 file types: SMPS which has aerosol size distribution, CCN_colA which contains CCN at different supersaturations, CCN_colB which contains CCN at constant supersaturation, ACSM which contains aerosol chemistry from an ACSM, NEPH which contains spectral aerosol scattering and backscattering and PSAP which contains spectral aerosol absorption. ACSM and CCN_colA are for hourly data, the rest are provided in both hourly and 5 minute resolution. There are also README files for each filetype and site. Additionally, there is a location file for the one mobile measurement site. Data files are in csv format; Readme files are in txt format.
