NOTE: Page under construction!

On this page we include information relevant to the persistent organic pollutant (POPs) simulation in GEOS-Chem.

PAH simulation

This update was tested in the 1-month benchmark simulation v9-02c and approved on 29 Nov 2012.

A simulation for polycyclic aromatic hydrocarbons (PAHs) has been added to GEOS-Chem v8-03-02 following Friedman and Selin (2012). Three separate PAHs are modeled: phenanthrene (PHE), pyrene (PYR), and benzo[a]pyrene (BaP). Separate modules have been created for each of the PAHs. Users can choose between different compounds in the input file.

PCB simulation

Previous issues that are now resolved

Prevent error when reading global OC

In GeosCore/global_oc_mod.F, we have:

     ! Data is only available for 2005-2009
     IF ( THISYEAR < 2005 ) THEN
        YEAR = 2005
     ELSE IF ( THIS YEAR > 2009 ) THEN
        YEAR = 2009
     ELSE
        YEAR = THISYEAR
     ENDIF

     ! Get the TAU0 value for the start of the given month
     XTAU = GET_TAU0( THISMONTH, 1, THISYEAR )

To avoid a segmentation fault error when THISYEAR is outside of 2005-2009, we must change XTAU to:

     ! Get the TAU0 value for the start of the given month
     XTAU = GET_TAU0( THISMONTH, 1, YEAR )
