Table 1 List of measurements performed with the various instruments discussed in this paper. All of the measurements were continuously operated in the Swiss container, obtaining real-time data.
Measurement | Instrument | Size range | Native time resolution |
|---|---|---|---|
Bulk size-resolved chemical composition and mass concentration of non-refractory submicron aerosols | High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS, Aerodyne Research, Inc.) | <1 µm (vacuum aerodynamic diameter, dva) | ~90 s |
Bulk equivalent black carbon mass concentration | Aethalometer (model AE33, Magee Scientific) | Behind switching valve, hence depending on inlet | 1 s |
Coarse mode aerosol size distributions | Aerodynamic Particle Sizer (APS model 3321, TSI) | 500 nm - 20 µm (aerodynamic diameter, da) | 20 s |
Size-resolved number concentrations and fluorescence of aerosols | Wideband Integrated Bioaerosol Sensor (WIBS NEO, DMT) | 500 nm - 20 µm (optical diameter, dopt) | 125 Hz single-particle counter |
CCN number concentrations at various supersaturation levels | Cloud Condensation Nuclei Counter (CCNC model CCN-100, DMT) | Behind switching valve, hence depending on inlet | 1 s |
Aerosol number concentrations | Condensation Particle Counter (CPC, model 3025 and 3776, TSI) | CPC 3025 (interstitial inlet): 3 nm -<1 µm CPC 3776 (total inlet): 2.5 nm - 10 µm (dopt) | 10 s |
