On this page we track the evolution of the mean OH concentration in GEOS-Chem. This value is an indicator of how "hot" the chemistry is. Please also see the related topic about the methyl chloroform lifetime in GEOS-Chem.
Computation of the mean OH diagnostic
Routine DO_DIAG_OH (in module GeosCore/diag_oh_mod.F) sums up the tropospheric air mass and mass-weighted OH mass after each call to the chemistry solver. The summing happens in these lines of code:
! Skip non-chemistry boxes IF ( .not. State_Met%InChemGrid(I,J,L) ) CYCLE ! Dry air density [molec/cm3] ! Cast to REAL*8 to avoid underflow AIRDENS_8 = State_Met%AIRNUMDEN(I,J,L) ! Box volume [cm3] ! Cast to REAL*8 to avoid underflow VOLUME_8 = State_Met%AIRVOL(I,J,L) * 1e+6_fp ! Sum air mass term into AIR_MASS array XAIRMASS = AIRDENS_8 * VOLUME_8 AIR_MASS(I,J,L) = AIR_MASS(I,J,L) + XAIRMASS ! Sum OH mass term into OH_MASS array XOHMASS = State_Chm%Species(I,J,L,id_OH) * XAIRMASS OH_MASS(I,J,L) = OH_MASS(I,J,L) + XOHMASS
where the arrays contain the following quantities:
I,J,L = 3-D array indices AIRDENS_8 = air density [molec/cm3] VOLUME_8 = grid box volume [cm3] AIR_MASS(I,J,L) = air mass [molec air] State_Chm%Species(I,J,L,id_OH) = OH concentration [molec OH/cm3] OH_MASS(I,J,L) = mass-weighted OH = OH mass * air mass [molec OH/cm3 * molec air]
After the GEOS-Chem simulation finishes, the mean OH value is printed out in subroutines PRINT_MEAN_OH (in module GeosCore/diag_oh_mod.F):
! Total Mass-weighted OH [molec OH/cm3] * [molec air] SUM_OHMASS = SUM( OH_MASS ) ! Atmospheric air mass [molec air] SUM_MASS = SUM( AIR_MASS ) ! Divide OH [molec OH/cm3 * molec air] by [molec air] and report as [1e5 molec/cm3] OHCONC = ( SUM_OHMASS / SUM_MASS ) / 1d5 ! Write value to log file WRITE( 6, '(/,a)' ) REPEAT( '=', 79 ) WRITE( 6, * ) 'ND23: Mass-Weighted OH Concentration' WRITE( 6, * ) 'Mean OH = ', OHCONC, ' [1e5 molec/cm3]' WRITE( 6, '( a)' ) REPEAT( '=', 79 )
Typical values are around 105 or 115 molec/cm3.

Evolution of mean OH in GEOS-Chem
Plot of mean OH evolution
Here is a plot of the mean OH concentration from GEOS-Chem 1-year benchmark simulations through version 12.8.0 (released 04 May 2020). The mean OH is an indicator how the chemistry mechanism is performing. Typical values are 10–12 x 105 molecules cm-1.
