Abstract NO x 4 × 4  km2 Comprehensive Air Quality Model with Extensions (CAMx) simulation during April–September 2019 in eastern Texas to evaluate the multiple challenges that arise from reconciling the NO x NO 2 + 17  % in urban areas) when transitioning from the TROPOMI NO 2 + 25  %) in the city centers and smaller differences (+ 5  %) in less polluted areas. We find that lightning NO x NO 2 NO x NO x NO 2 NO x - 13  %) and Houston (- 20  %). In the vicinity of large power plant plumes (e.g., Martin Lake and Limestone) we find larger disagreements, i.e., the satellite NO 2 NO 2 NO 2 NO 2 NO 2 NO x/NO 2 NO 2 - 9  % underestimate in eastern Texas and - 21  % in areas of central Texas with lower biogenic volatile organic compound (VOC) emissions. Ozone formation regimes at the time of the early afternoon overpass are NO x NO x NO 2 and HCHO from the upcoming TEMPO (Tropospheric Emissions: Monitoring Pollution) mission. This study highlights that TROPOMI measurements offer a valuable means to validate emissions inventories and ozone formation regimes, with important limitations.
