Some notebooks for S5P-LNO2.
Zhang et al., Spaceborne observations of lightning NO2 in the Arctic, Environ. Sci. Technol.
Input data are all saved in the zenodo Dataset called Dataset for "Spaceborne observations of lightning NO2 in the Arctic".
Users can download the compressed file, extract it in the root directory, and rename to data. Then, all the Jupyter Notebooks should work well.
