Aerosol physical properties

Description

Key information

Original physical properties of aerosols are documented in Liu et al. (2012).¹ Detailed information is included in the supplement.
Physical properties of aerosols used in E3SMv1 are documented in Wang et al. (2020).²
Marine organic aerosol properties are defined in Burrows et al. (2022).³
Dust refractive index and longwave absorption coefficients are updated by Feng et al. (2022).⁴
BC and POM hygroscopicity values are updated by Shan et al. (2024).
Physical properties of the fifth mode aerosols are documented by Ke et al. (2024).

Included fields

Mode properties

Geometric standard deviation of each lognormal mode
Nominal geometric mean diameter and its lower/upper bound of values for each mode
Coefficients of polynomial expression (lookup-table) for extinction, absorption, and asymmetry parameter calculations
Aerosol refractive index table needed for interpolation (lookup-table) calculation (for different wavelengths)
Crystalization and deliquesence relative humidity thresholds for aerosol wateruptake calculations

Species properties

Aerosol refractive index for each species
Density for each species
Aerosol hygroscopicity for each species
Note that some of variables in the species property file are for bulk aerosols, so we ignore the description for them.
