PARTYPE

Particle types for user-defined OPAC aerosols

Attributes

float | continuous | dynamic | cm-3 | basic

Description

The variable PARTYPE defines the particle types used as components of the user-defined OPAC aerosol model (AERTYPE), thus allowing users to introduce additional user-defined aerosols based on the versatility offered by OPAC. The available aerosol components are shown in the Table below together with their minimum/maximum and default number-density values in cm-3:

Note that a maximum of 5 different aerosol components can be selected to define a new aerosol type.

Further information about these aerosol parameters and refractive indices can be found in (Hess et al., 1998) and (Koepke et al., 2015).
