FRIDGE-STD: Goethe University of Frankfurt ice nucleation deposition freezing experiment standard process (particles on Si wafer processed in low pressure diffusion chamber

Sample: FIN-02 filter or shared impinger for the given date, or a specific filter number for a given technique (when multiple filters collected on a given day for that technique)

Temp: temperature (deg C)

INP Conc.: ice nucleating particle number concentration (m^-3) based on total sample volume

ci INP+: positive increment confidence interval for INP concentration

ci INP-: negative increment confidence interval for INP concentration
Total particles: total particle number concentration as measured by a condensation particle counter

Sfc area: surface area concentration (um^2 cm^-3) calculated as an integrated value over the sampling period on the basis of a lognormal fit to the aerosol size distribution data (see manuscript)

Frac: ice nucleation active fraction (INP conc./total particles when in the same units)

frac_ci+: positive increment confidence interval for ice active fraction

frac_ci-: negative increment confidence interval for ice active fraction

ns,geo: surface active site density (m^-2) calculated on the basis of spherical equivalent geometric surface area

ns,geo ci+: positive increment confidence interval for geometric surface active site density

ns,geo ci-: negative increment confidence interval for geometric surface active site density
Ice threshold: threshold size for measuring particles as ice crystals in micrometers where calibrated, by optical particle counter channel (Chnl), or if determined by optical depolarization with machine learning methods

Drop/aliquot volume: where applicable, in microliters

Notes: special notes regarding processing, whether picking selected temperature points or binning multiple temperature scans of data for offline measurement of immersion freezing.
