    Accurate space-based NO<sub><i>x</i></sub> emission estimates with the flux divergence approach require fine-scale model information on local oxidation chemistry and profile shapes by F. Cifuentes, F. Cifuentes, H. Eskes, E. Dammers, E. Dammers, C. Bryan, F. Boersma, F. Boersma

    Published 2025-02-01
    “…<p>The flux divergence approach (FDA) is a popular technique for deriving <span class="inline-formula">NO<sub><i>x</i></sub></span> emission estimates from tropospheric <span class="inline-formula">NO<sub>2</sub></span> columns measured by the TROPOspheric Monitoring Instrument (TROPOMI) satellite sensor. An attractive aspect of the FDA is that the method simplifies three-dimensional atmospheric chemistry and transport processes into a two-dimensional (longitude–latitude) steady-state continuity equation for columns that balances local <span class="inline-formula">NO<sub><i>x</i></sub></span> emissions with the net outflow and chemical loss of <span class="inline-formula">NO<sub><i>x</i></sub></span>. …”
