UCX_ProdLoss.v11-02d.4x5.72L.nc

  -- File containing the 3D production and loss rates [molec/cm3/s] for 
     all advected and chemically active species obtained from the GEOS-Chem
     v11-02d-Run2 1-year benchmark simulation using UCX and 4x5 GEOS-FP met
     fields. The 1-year simulation was spun up for 1 year.
