title: Inversion-based assessment of anthropogenic NO <sub> <i>x</i> </sub> emission changes in Ukraine during the 2022–2023 war using TROPOMI satellite data
abstract: Abstract. The outbreak of the Russia–Ukraine war in 2022 brought a huge impact on the Ukrainian society. We utilized TROPOMI nitrogen dioxide (NO2) observations to constrain the Emissions Database for Global Atmospheric Research (EDGAR) inventory and inverted daily anthropogenic nitrogen oxides (NOx) emissions in Ukraine from 2019 to 2023. Our results reveal a 15 % reduction in NOx emissions during the 2022 war and an 8 % reduction in 2023, both substantially exceeding the decrease caused by the
