I’m trying to estimate pH value in the cloud water using CCTM results and MCIP results.
I know this is really basic problem, but I want to know whether my thinking is right or not and the most appropriate method.
First, I estimated pH value using OH concentration from ACONC file since pH can be calculated through the formula ‘pH = 14 - pOH’.
But this method is not suitable because the OH concentration from ACONC file does not mean OH concentration in the cloud water.
And then, I tried to find any species in MCIP results for estimating the pH value, but I couldn’t find suitable species.
So, I want to know how to estimate or calculate pH value in the cloud water using CMAQ CCTM or MCIP results.
And other ideas are also okay.
I hope any response for my question, please let me know any ideas from you.
