Ae. Heathfield et al., Infrared and visible Fourier-transform spectra of sulfuric-acid-water aerosols at 230 and 294 K, APPL OPTICS, 38(30), 1999, pp. 6408-6420
The extinction spectra of aqueous sulfuric acid aerosols fully covering the
mid-IR to visible regions from 750 to 23,000 cm(-1) (13.9-0.4 mu m) have b
een measured in the laboratory with a Fourier-transform spectrometer. Both
large and small aerosol particles with compositions of approximately 60-70-
wt.% H2SO4 were generated and their spectra recorded at 230 and 294 K. The
spectra were fitted to a model incorporating roam-temperature refractive-in
dex data [Appl. Opt. 14, 208 (1975)] and Mie theory calculations to charact
erize the composition and size distributions of the aerosol samples. (C) 19
