- W4293313304 abstract "<strong class=journal-contentHeaderColor>Abstract.</strong> Satellite observations of tropospheric NO<span class=inline-formula><sub>2</sub></span> columns can provide top-down observational constraints on emissions estimates of nitrogen oxides (<span class=inline-formula>NO<sub><i>x</i></sub></span>). Mass-balance-based methods are often applied for this purpose but do not isolate near-surface emissions from those aloft, such as lightning emissions. Here, we introduce an inverse modeling framework that couples satellite chemical data assimilation to a chemical transport model. In the framework, satellite-constrained emissions totals are inferred using model simulations with and without data assimilation in the iterative finite-difference mass-balance method. The approach improves the finite-difference mass-balance inversion by isolating the near-surface emissions increment. We apply the framework to separately estimate lightning and anthropogenic <span class=inline-formula>NO<sub><i>x</i></sub></span> emissions over the Northern Hemisphere for 2019. Using overlapping observations from the Ozone Monitoring Instrument (OMI) and the Tropospheric Monitoring Instrument (TROPOMI), we compare separate <span class=inline-formula>NO<sub><i>x</i></sub></span> emissions inferences from these satellite instruments, as well as the impacts of emissions changes on modeled NO<span class=inline-formula><sub>2</sub></span> and O<span class=inline-formula><sub>3</sub></span>. OMI inferences of anthropogenic emissions consistently lead to larger emissions than TROPOMI inferences, attributed to a low bias in TROPOMI NO<span class=inline-formula><sub>2</sub></span> retrievals. Updated lightning <span class=inline-formula>NO<sub><i>x</i></sub></span> emissions from either satellite improve the chemical transport model's low tropospheric O<span class=inline-formula><sub>3</sub></span> bias. The combined lighting and anthropogenic emissions updates improve the model's ability to reproduce measured ozone by adjusting natural, long-range, and local pollution contributions. Thus, the framework informs and supports the design of domestic and international control strategies." @default.
