Short summary

NO_x is a precursor to hazardous tropospheric ozone and can be emitted from various anthropogenic sources. It is important to quantify NO_x emissions in urban environments to improve the local air quality, which still remains a challenge, as sources are heterogeneous in space and time. In this study, we calculate NO_x emissions over Los Angeles, based on aircraft measurements in June 2021, and compare them to a local emission inventory, which we find mostly overpredicts the measured values.
