Top-down estimates using satellite data provide important information on the sources of air pollutants. We develop a sector-based 4D-Var framework based on the GEOS-Chem adjoint model to address the impacts of co-emissions and chemical interactions on top-down emission estimates. We apply OMI NO<sub>2</sub>, OMI SO<sub>2</sub>, and MOPITT CO observations to estimate NO <sub><i>x</i></sub> , SO<sub>2</sub>, and CO emissions in East Asia during 2005-2012. Posterior evaluations with surface measure ...[more]
