<p>Nitrogen oxides (NO<sub><i>x</i></sub> = NO + NO<sub>2</sub>) are air pollutants primarily emitted from anthropogenic sources, however, bottom-up anthropogenic NO<sub><i>x</i></sub> emission inventories often suffer from update delays.

Description

The TROPOspheric Monitoring Instrument (TROPOMI) provides near-real-time, high-resolution NO<sub>2</sub> column densities, offering new opportunities for timely NO<sub><i>x</i></sub> emission prediction.

Given the short lifetime of NO<sub><i>x</i></sub> in the lower troposphere, local emissions can influence observations over distances of ~100 km. In this study, we develop a convolutional neural network to predict anthropogenic NO<sub><i>x</i></sub> emissions from TROPOMI NO₂ observations. The model operates at a monthly temporal resolution and 0.1 ° × 0.1 ° spatial resolution over Europe and the continental United States, using TROPOMI NO<sub>2</sub> columns and ERA5 wind fields as inputs, with EDGARv8.1 emissions as training targets.

Trained on 2019–2020 data, the model achieves an R<sup>2</sup> of 0.958 and an RMSE of 8.194 Mg/month/cell on the test set. It demonstrates strong temporal generalisation, with an average R<sup>2</sup> of 0.927 at the grid scale and 0.966 at the national scale during 2021–2022, although spatial generalisation remains limited. The model is applied to extend gridded NO<sub><i>x</i></sub> emissions to December 2025.

Overall, the proposed satellite-driven deep learning approach enables accurate, high-resolution, and near-real-time updates of anthropogenic NO<sub><i>x</i></sub> emissions.</p>
