== [=#salsa_input '''Aerosol input file'''] ==

The aerosol input file contains information needed to setup aerosol emissions. Aerosol emission value can be given applying two alternative level of detail (lod): 1 or 2. See [../../../tec/aerosol aerosol module documentation] for further details.

{{{#!td
Emission values of aerosol particles per size bin. The coordinates vary based on the chosen level of detail.\\

{{{lod=1}}}: Emissions are provided per emission category and yearly as total PM in dimensions {{{aerosol_emission_values(y,x,ncat)}}}. They are then scaled by pre-defined rescaling factors '''emission_time_factors'''. Default categories are ''traffic exhaust'', ''road dust'', ''wood combustion'', ''other''.//

{{{lod=2}}}: Emissions are provided per aerosol size bin for each surface point in space and at given points in time in dimensions {{{aerosol_emission_values(time,y,x,Dmid)}}} and in units # m^-2^ s^-1^. The bin mean diameter ''Dmid'' given in nm.
