ACROSS_LISA_PRG_CRI_PM1_1-H_L3

The complex refractive index (n-ik) was retrieved based on optical calculations using as input the spectral absorption and scattering coefficients and the number particle size distribution measured at the surface for the PM1 fraction at the ground–based PRG urban site during the ACROSS field campaign. Used datasets for the retrieval are:
- ACROSS_LISA_PRG_AETH-Abs_PM1_1-Min_L2
- ACROSS_LISA_PRG_NEPH_Scatt-Backscatt_PM1_1-Min_L2
- ACROSS_LCE_PRG_SMPS_5 min_L2
- ACROSS_LISA_PRG_OPC_Sizedistr_PM1_1-Min_L2

Data are provided at 1 hour temporal resolution and at seven wavelengths between 370 and 950 nm. The standard deviation indicates the uncertainty of the complex refractive index retrieval.
The methodology and results are presented in Di Antonio et al. (2024).
