Preferred Label : scattering cross-section;
Detailed label : scattering cross-section, σscat;
IUPAC definition : The scattering coefficient per particle (cm2/particle); \[b_{{scat}} n\ σ _{{scat}}\]
where n is the number concentration of particles (particles cm-3) and σ scat is the
scattering cross-section. bscat, the scattering component of extinction due to gas
and particles, is measured in the atmosphere using a nephelometer. For a homogeneous
atmosphere it is related in theory to the meteorological range (LV): LV 3.9/bscat;
bscat and babs represent the scattering and absorption coefficients per unit length
for a light beam (of path length L) which has a spectral radiance (intensity) i0 incident
on a sample of air and I is the transmitted spectral radiance (intensity), ln ( I
0 I ) L ( b scat b ab.;
