Urban and power plant NOx emissions in Sub-Saharan Africa inferred from TROPOMI

Abstract

Please read abstract in the article.

Description

DATA AVAILABILITY STATEMENT : The bottom-up annual anthropogenic NOx emissions from the northeast South Africa inventory for 2019 and the DACCIWA inventory for 2018 are available for download from the UCL Research Data Repository (https://doi.org/10.5522/04/30530147) (Marais, Naidoo, & Keita, 2025). The GEOS-Chem source code used in this work is available for download from Zenodo (The International GEOS-Chem User Community, 2021). ERRATUM : The originally published version of this article contained an error in the heading for Section 2.2. “TROPOMI NO2 Data and Hotspot Selection” has been corrected to the following: “Top-Down Estimates of Hotspot NOx Emissions.” This may be considered the authoritative version of record.
