MAERO

Aerosol model

Attributes

integer | discrete | dynamic | unit-less | basic

Description

The variable MAERO selects one of the predefined aerosol model or coupled with OPAC aerosol database, thus defining the aerosol optical properties (i.e., extinction, absorption and scattering). The available options are shown in the Table below:

User's components
This option allows users to select a stored and predefined aerosol model from the Aerosol Toolkit based on a composition of basic aerosol particles.

Opac Not yet implemented!
This option allows users to input OPAC aerosol optical properties.

* Parameters and refractive indices based on (d'Almeida et al., 1991).
Parameters and refractive indices based on (Russel et al., 1996).

This variable, therefore, has an impact on the simulation of the absorption-scattering processes caused by suspended particles in the sun-target-sensor optical path.

The amount of suspended particles is specified separately from the Aerosol Optical Thickness (AOT) key input variable.
