Top-down emissions of non-methane volatile organic compounds (VOCs) calculated by an inverse modeling during the 2016 KORUS-AQ campaign

The data set provides two top-down emission inventories of non-methane volatile organic compounds (VOCs) calculated by a two-step Hybrid Iterative Finite Difference Mass Balance and four-dimensional variational method inversion system (Hybrid IFDMB-4DVar), which is developed by "an inversion framework for optimizing non-methane VOC emissions using remote sensing and airborne observations in Northeast Asia during the KORUS-AQ field campaign" (Choi et al., to be submitted). The data has a horizontal resolution of 0.25°x0.3125° and the domain covers Korea and Eastern China. The data includes emissions of CH2O, C2H4, C2H6, C3H8, large alkenes (PRPE), large alkanes (ALK4), benzene (BENZ), toluene (TOLU), xylene (XYLE), isoprene (ISOP), methyl ethyl ketone (MEK), acetone (ACET), and acetaldehyde (ALD2) from anthropogenic (_an), biogenic (_bg), and biomass burning (_bb) sources.

A chemical transport model, GEOS-Chem, and its adjoint were used for the inverse modeling. The a priori emissions were taken from KORUSv5, MEGANv2.1, and QFEDv2.5 inventories. The CH2O measurements from two satellites (OMI and OMPS) and DC-8 aircraft during the 2016 KORUS-AQ campaign were utilized.

The data set is associated with the article "An inversion framework for optimizing non-methane VOC emissions using remote sensing and airborne observations in Northeast Asia during the KORUS-AQ field campaign (Choi et al., to be submitted)".
