The dataset includes results from a combination of TROPOMI NO2 measurements and GLD360 observations in the Arctic (June-August 2021). By analyzing consecutive TROPOMI NO2 observations, we determine the lifetime and production efficiency of lightning NO2. A detailed description of the methodology can be found in Zhang et al. (2023).

Date files These NetCDF files are generated by S5P-LNO2 which depends on TROPOMI NO2 data and GLD360 lightning data.
