With the development of the COVID-19 pandemic and the resulting slowdown in economic activity, first in China and then in the rest of the world, anthropogenic emissions of primary pollutants were significantly altered after January 2020. This unanticipated planet-wide experiment allows us to examine the response of the atmosphere's chemical system and in particular, the formation of secondary compounds such as

COVID-19 caused an historic collapse in fossil fuel demand, a general decline in economic activity and hydrocarbon price volatility. This resulted in an unprecedent scenario to evaluate the contribution of the oil and gas industry (O&G) to methane (CH 4 ) and nitrogen dioxide (NO 2 ) emissions in the Permian basin (U.S.), currently the second largest hydrocarbon-bearing area on Earth. TROPOMI (Tropospheric Monitoring Instrument), on board the Sentinel-5P satellite, has captured the impact of the oil and gas industry during the COVID-19 lockdown. Production and drilling declined (13 % and 68 % respectively) during the lockdown, causing a generalized drop (˜30 %) of NO 2 emissions derived using the divergence method in comparison with 2019. NO 2 tropospheric columns were less impacted with a smaller decrease (˜4 %) across the basins. On the other hand, the impact of the lockdown in methane (increase of 0.1 % to 0.3 % across the basins) was not as evident as in the NO2, because of the large background cause by the long lifetime (12 years), the variability of the meteorology, and the limited temporal sampling due to the strict thresholds of the retrieval algorithm. This study demonstrates that the impact of the COVID-19 lockdown on NO 2 and CH 4 emissions was not only present in urban areas but also in vast O&G production regions, which shows the potential of TROPOMI to assess future pollution mitigation strategies for this industry.
