BackForward Variable: Aerosol type

Full name Aerosol type
Definition Selection, out of a pre-defined set of aerosol classes, that best fits an input data set (observed or modeled). The pre-defined set of aerosol classes includes specification of the particle composition, mixing state, complex refractive index, and shape as a function of particle size. The definition of aerosol type includes specification of all the classes as well as the algorithm used to choose the best fit to the input data.
Measuring Units Classes Uncertainty Units Probab.
Horizontal Res Units Vertical Res Units
Stability Units Probab. (Stability /decade)


Comment: Uncertainty is expressed as the probability that the selected class is incorrect, i.e., that the true class is different from the selected class. Examples of input data sets include (a) multi-angle, multi-spectral, and/or polarization measurements of upwelling or downwelling radiances observed from space, from the surface, or from airborne platforms; and, (b) modeled or observed aerosol chemical composition as a function of particle size, possibly including the state of mixture of various species in individual particles (e.g., mineral ash coated with sulfuric acid).
