All runs used GCHP 14.2.2
The GEOS-IT run uses code that also included the GEOS-IT meteorology development merged in.
Each file compares passive tracer in the start (ref) and end (dev) restart files for a 1-year benchmark simulation.
All runs use the same initial conditions, i.e. ref is the same for plots.
Only full column zonal mean is plotted.
