ri_brine
Constants
Sea-salt aerosol (deliquesced brine) complex refractive index m = n + i k, wavelength in nm. Assumptions: maritime haze surrogate; aqueous brine droplet at ~300 K; morphology not modeled. Guidance/sources (composite, smoothed):
- Refractive index of seawater/brine in visible n≈1.37–1.40 (dependent on salinity and wavelength).
- Hale & Querry (1973) water bands for k behavior in IR; salt slightly perturbs n, k remains water-like.
- Querry NaCl for dry-salt context; here we target deliquesced brine typical for haze. Notes:
- Visible k is extremely small; we use tiny nonzero values for numerical stability.
- MIR/LWIR follow water band structure but with slightly different n baseline.
- Coverage: 200–20,000 nm; denser near 3 µm and 6–10 µm regions.
