Summary: | The dataset includes results from a combination of TROPOMI NO2 measurements and GLD360 observations in the Arctic (June-August 2019). 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). Reference Zhang et al., Spaceborne observations of lightning NO2 in the Arctic, Environ. Sci. Technol. Date files These NetCDF files are generated by S5P-LNO2 which depends on TROPOMI NO2 data and GLD360 lightning data. Here is the variable table of the S5P-LNO2 NetCDF product: Varname Group Units Description time S5P days since <yyyy-mm-dd> time using proleptic gregorian calendar latitude S5P degrees_north pixel center latitude longitude S5P degrees_east pixel center longitude air_mass_factor_clear S5P 1 Air mass factor for the cloud-free part of the scene air_mass_factor_cloudy S5P 1 Air mass factor for the cloud-covered part of the scene air_mass_factor_stratosphere S5P 1 Stratospheric air mass factor air_mass_factor_total S5P 1 Total air mass factor air_mass_factor_troposphere S5P 1 Tropospheric air mass factor Apparent_scene_pressure S5P Pa Scene pressure from the cloud product assembled_lat_bounds S5P degrees_north assembled_latitude_bounds calculated by Satpy assembled_lon_bounds S5P degrees_east assembled_longitude_bounds calculated by Satpy Averaging_kernel S5P 1 Averaging kernel cloud_albedo_crb S5P 1 Cloud albedo in the cloud product cloud_fraction_crb_nitrogendioxide_window S5P 1 Cloud fraction at 440 nm for NO2 retrieval cloud_pressure_crb S5P Pa Cloud optical centroid pressure cloud_radiance_fraction_nitrogendioxide_window S5P 1 Cloud radiance fraction at 440 nm for NO2 retrieval Geolocation_flags S5P 1 Some flags (see ATBD) lightning_mask S5P 1 <0: labeled lightning with fire; 0: no lightning; >0: labeled lightning without fire nitrogendioxide_ghost_column S5P mol m-2 Ghost column NO2: modelled NO2 column below the cloud top nitrogendioxide_segmentation S5P ... |
