13 : !> aerosol_state defines the interface to the time-varying aerosol state
14 : !! variables (e.g., mixing ratios, number concentrations). This includes the
15 : !! aerosol portion of the overall model state.
16 : !!
17 : !! Each aerosol package (e.g., MAM, CARMA, etc) must extend the aerosol_state
18 : !! class to allow access to the state information (transported and not transported)
19 : !! of the aerosol package. Any package must implement each of the deferred
20 : !! procedures of the abstract aerosol_state class, may include additional private
21 : !! data members and type-bound procedures, and may override functions of the
22 : !! abstract class.
23 : !!
24 : !! Please see the modal_aerosol_state module for an example of how the aerosol_state
25 : !! class can be extended for a specific aerosol package.
