Mapping NO x emissions in Cyprus using TROPOMI observations: evaluation of the flux-divergence scheme using multiple parameter sets.

ABSTRACT: The production of nitrogen oxides (NO x = NO + NO 2 ) is substantial in urban areas and from fossil fuel-fired power plants, causing both local and regional pollution, with severe consequences for human health. To estimate their emissions and implement air quality policies, authorities often rely on reported emission inventories. The island of Cyprus is de facto divided into two different political entities, and as a result, such emissions inventories are not systematically available for the whole island. We map NO x emissions in Cyprus for two 6-month periods in 2021 and 2022 with a flux-divergence scheme, using spaceborne retrievals of nitrogen dioxide (NO 2 ) columns at high spatial resolution from the TROPOMI instrument, as well as horizontal wind data to derive advection and concentra
