Dear authors,

I still find inconsistent units in section 2.2. [x] means dimension of x.
For instance, eq. 1: [y]=1 (condensed mass per unit mass of air).
Thus [lhs]= 1/T (inverse time)
However, [rhs] = M/T (mass per time)
unless the molecular weight in the definition of alpha is in dimensionless units. Is this so?

Another example: Eq. between 3 and 4 (line 185):
[r]=1 (mixing ratio) , [N]= 1/L^3 (L: length), [y]=1, thus I find [lhs]=1, but [rhs]=1/L^3.

Please check these equations and the interpretation of the variables.
As I did not test all derivations, please check also equations in the remaining part of the paper.

I have your 2nd revised version on the table and would like to make the final (positive) decision. But unfortunately, I still cannot accept it because I find inconsistent units in your equations. Let’s try to get that sorted out, perhaps I misunderstand something.

Let’s first look at the variable alpha which is 2 pi D M /RT. So we have
[D] = m^2/s
[M] = kg/mol
[RT] = J/mol
and together this gives [alpha]=s. Right?

Let’s now look at Eq. 1. Here we have
[y]=kg thus for the lhs of Eq. we have [dy/dt]=kg/s
[p]=N/m^2
and for the rhs of Eq 1 we have [alpha*D*(delta p)]=N which is inconsistent with the kg/s of the lhs.

Please, if I am incorrect, explain me what in my calculation is wrong.
Otherwise, correct your equations and send me a revised version together with an account of the changes that you have made to the current equations.
