BackForward Variable: Aerosol Extinction Coefficient

Definition
Full name Aerosol Extinction Coefficient
Definition 3D field of spectral volumetric extinction cross-section of aerosol particles.
Measuring Units m-1 Uncertainty Units m-1
Horizontal Res Units km Vertical Res Units km
Stability Units m-1 (Stability /decade)

 

Comment: The scattering and absorption components of aerosol extinction coefficient are called "aerosol scattering coefficient" and "aerosol absorption coefficient" May be specified as a size-dependent quantity.
