The dataset includesresults from a combination of TROPOMI NO 2 measurementsand GLD360 observations in the Arctic ( June-August2020 ).By analyzing consecutive TROPOMI NO 2 observations, we determine the lifetime and production efficiency of lightning NO 2 .A detailed description of the methodology can be found in Zhang et al. (2023) . Reference Zhang et al., Spaceborne observations of lightning NO 2 in the Arctic , Environ. Sci. Technol. Date files These NetCDF files are generated by S5P-LNO2 which depends on TROPOMI NO 2 data and GLD360 lightning data.
