N_CN_SMPS_STP

Total particle number concentration from SMPS at STP (see P_SMPS, T_SMPS) (cm⁻³). Referred to as N_tot,SMPS in manuscript text.

P_SMPS

Sample pressure from SMPS (hPa).

T_SMPS

Sample temperature from SMPS (°C).

RH_SMPS

Sample relative humidity from SMPS (%).

N_CN_CPC_STP

Total particle concentration from CPC at STP (cm⁻³). Referred to as N_tot,CPC in manuscript text.

Qc_CPC_SMPS

Quality check of number closure. Flag indicates comparison of N_CN_SMPS_STP and N_CN_SMPS_STP. Qc = 0 differences smaller than 50%; Qc = 1 differences bigger than 50%.

Qc_ACSM_SMPS

Quality check of PM₁ mass closure. Flag indicates comparison of Mass_ACSM_PSAP_STP and Mass_SMPS_STP. Qc = 0 for differences smaller than 50%; Qc = 1 for differences bigger than 50%.

Qc_Neph_SMPS

Quality check of scattering closure. Flag indicates comparison of calculated aerosol scattering coefficient and BsG1_STP measured by the integrating nephelometer. Qc = 0 differences smaller than 50%; Qc = 1 differences bigger than 50%.

dN_i/dlogD_i (bin1, bin2,…,bin113)

Particle number size concentration at STP for each size bin¹ (cm⁻³). Referred to as dN_i/dlogD_i in manuscript text.
