These datasets are used to calculate vertical ship emission profiles based on model
simulation results from the microscale chemistry, transport and stream model (MITRAS).

Two different parameterization schemes are applied:
a) Gaussian profile
b) Exponentially modified Gaussian profile with upper plume boundary (Hup). 

The Expgauss profile delivers best performance when values above the upper plume 
boundary are set to zero.

The Python codes allow the user to calculate vertical concentration profiles based on
their individual input. Input values are:
- Wind speed
- Wind direction (flow angle)
- Exhaust gas temperature at the ship stack
- Gas exit velocity
- Atmospheric stability at stack height

The parameterization is based on a ship of 50 m height. For a different ship height, 
the user needs to lower the whole profile by the height difference of their own ship 
height.
