Description
Aerosol properties were measured between February 8 and March 31, 2019 at the Weissfluhjoch site. The dataset includes particle concentrations and size distributions in fine and coarse modes, cloud condensation nuclei concentrations, and ice nuclei particle concentrations. Data collection was performed by ENVIDAT using optical and aerodynamic particle counters, a scanning mobility particle size spectrometer, and an ice nuclei counter.
Use Cases
Analyze temporal trends in fine-mode particle concentrations (10-1000 nm) and coarse-mode particles (>1000 nm) from optical particle counter data.
Correlate cloud condensation nuclei concentrations (CCNCs) with ice nuclei particle concentrations (ICNCs) to study aerosol impacts on cloud formation.
Model particle size distributions using data from the Scanning Mobility Particle Size Spectrometer (SMPS) for the 12-460 nm electrical mobility diameter range.
Investigate immersion freezing mode ice nucleation using particle samples collected by the Coriolis μ microbial air sampler and analyzed by the LINDA apparatus.
Strengths
Data collection covers a specific 52-day period from February 8 to March 31, 2019, providing a focused temporal snapshot.
Measurements integrate multiple specialized instruments (OPC, APS, SMPS, ice nuclei counter) for a multi-faceted view of aerosol properties.
Geographic location is precisely specified with coordinates (LON: 9.806475, LAT: 46.832964) at the high-altitude Weissfluhjoch site.
Limitations
Temporal coverage is limited to approximately 7 weeks in early 2019, restricting analysis of seasonal or long-term trends.
Dataset size, row count, and specific file formats are unknown, complicating assessment of data volume and structure.
Spatial coverage is limited to a single measurement station, which may not be representative of broader regional conditions.
