…RT_MOSAIC_4BIN_KPP) and 202 (MOZART_MOSAIC_4BIN_AQ_KPP). (#1813) Fixed a bug for chem_opt = 201, 202. TYPE: bug fix KEYWORDS: MOZART_MOSAIC_4BIN, mozart_pH_diag, bug fix SOURCE: Internal DESCRIPTION OF CHANGES: Problem: Users will experience a stalled simulation upon writing history files. This was caused by the pH diagnostics added in v4.3 (#1342) not being activated with the namelist option mozart_ph_diag = 1. Solution: Add as optional arguments only filled if the namelist is activated.

The Jenkins tests have passed. RELEASE NOTE: This PR addresses a bug introduced in WRF v4.3 that affects users using chem_opts = 201 (MOZART_MOSAIC_4BIN_KPP) and 202 (MOZART_MOSAIC_4BIN_AQ_KPP).

DESCRIPTION OF CHANGES:
Originally submitted as PR #999, but was resubmitted due to inconsistencies
Alter Registry/registry.chem to include diagnostic pH variables ph_cw, ph_aer01, ph_aer02,
ph_aer03, and ph_aer04.
Modify files, listed below, to calculate and set pH diagnostic variables
MOZART is a gas-phase chemistry mechanism (set of reactions) in WRF-Chem
Diagnostics are activated with namelist,chem option mozart_ph_diag=1
MOSAIC is one of the aerosol models in WRF-Chem that represents the size distribution
of the aerosols with 4 size bins (hence "4bin")
The pH is calculated for each of the 4 aerosol size bins. That is why there are 4 variables: pH_aer1,
aer2, aer3, aer4.
pH is a diagnostic variable and is calculated as part of the aerosol model. However what we added
was the ability to write out the field to the history file. It is by default turned off as an output field,
but can be "turned on" using the iofields.txt file.
There is also cloud water pH (pH_CW) which is calculated as part of the cloud chemistry routine.
Same thing as aerosol pH, by default it is not an output field, but can be included in history files
via iofields.txt.
For pretty pictures and a description of what we learned, feel free to look at the report for the
ACOM lab: https://nar.ucar.edu/2019/acom/predicting-acidity-aerosols-and-cloud-water.
