Laboratory measurements of the optical properties of sea salt aerosol
Résumé
The extinction spectra of laboratory generated sea salt aerosols have been measured from 1 ?m to 20 ?m using a Bruker 66v/S FTIR spectrometer. Concomitant measurements include temperature, pressure, relative humidity and the aerosol size distribution. The refractive indices of the sea salt have been determined using a simple harmonic oscillator band model (Thomas et al., 2004) for aerosol with relative humidities between 0.1% to 100% sea salt. The resulting refractive index spectra show significant discrepancies when compared to existing sea salt refractive indices.
