Input File Format: Aerosol Distribution Profile

An aerosol distribution profile input file must consist of three lines:

The units of the rate line depend on the type of aerosol distribution profile:

Between the specified times the aerosol profile is interpolated step-wise and kept constant at its last value. That is, if the times are $t_i$, the rates are $r_i$, and the aerosol distributions are $a_i$ (all with $i = 1,\ldots,n$), then between times $t_i$ and $t_{i+1}$ the aerosol state is constant at $r_i a_i$. Before time $t_1$ the aerosol state is $r_1 a_1$, while after time $t_n$ it is $r_n a_n$.

Example: an emissions aerosol profile could be:

 time  0          600        1800       # time (in s) after simulation start
 rate  1          0.5        1          # scaling factor in m/s
 dist  dist1.dat  dist2.dat  dist3.dat  # aerosol distribution files
 

Here the emissions between 0 min and 10 min are given by dist1.dat (with the number concentration interpreted as having units 1/(m^2 s)), the emissions between 10 min and 30 min are given by dist2.dat (scaled by 0.5), while the emissions after 30 min are given by dist3.dat.
