Abstract. This study applies a mass-conserving model-free analytical approach to daily observations on grid-by-grid basis of NO2 from the Tropospheric Monitoring Instrument (TROPOMI) rapidly and flexibly quantify changing emerging sources NOx emissions at high spatial temporal resolution. The inverted optimized underlying ranges include quantification atmospheric in situ processing, transport, physics. results are presented over three regions China, including Shandong Hubei, which urbanizing not frequently addressed global literature. day-to-day found be 1.96 ± 0.27 µg m−2 s−1 pixels with available priori values (1.94 s−1), while 1.22 0.63 extra inventory is lower than 0.3 s−1. Source attribution based thermodynamics combustion temperature, processing successfully identifies five different industrial source types. Emissions these sites adjacent Yangtze River 161. 68.9 Kt yr−1 (163 % higher priori), consistent missing light medium industries located along river, contradicting previous studies attributing water as emissions. Finally, reveal an uncertainty larger variability, providing quantitative information for placement future monitoring stations. It hoped that findings will drive new top-down estimates, quantified updated continuously consistently remotely sensed measurements associated uncertainties actively reflect land-use changes misidentified emissions, quantifying datasets inform bottom-up community.
