Data for Significant influence of topography and the aerosol under special terrain on cloud-to-ground lightning in Sichuan Basin

<p>1. CG lightning data for June-August during the years of 2010-2018 used in the paper were detected by the China Lightning Detection Network and the spatial resolution is 0.01&ordm;&times;0.01&ordm;. This dataset describes lightning frequency in the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>2.&nbsp;Terrain data is obtained from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) in version 3 and the spatial resolution of terrain data is 0.02&ordm;&times;0.02&ordm;. The dataset describes terrain data in the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>3.&nbsp;Aerosol optical depth (AOD) data for June-August during the years of 2010-2018 are taken from the measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS) products MOD08 D3 aboard the Terra and Aqua satellites in the version of 6.1 with a spatial resolution of 1&ordm;&times;1&ordm;. This dataset describes the AOD value of the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>4.&nbsp;The wind field data and mid-level relative humidity used are from the ERA5 hourly data on pressure levels of the European Center for Medium Range Weather Forecasting (ECMWF) with a spatial resolution of 0.25&ordm;&times;0.25&ordm;. U is the eastward component of the wind. It is the horizontal speed of air moving towards the east. A negative sign indicates air moving towards the west. V is the northward component of the wind. It is the horizontal speed of air moving towards the north. A negative sign indicates air moving towards the south. The dataset describes wind field in the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>5.&nbsp;Convective available potential energy (CAPE) data used in the study are from the ERA5 hourly data on single levels of Medium Range Weather Forecasting (ECMWF) with a spatial resolution of 0.25&ordm;&times;0.25&ordm;. This dataset describes the CAPE value of the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>6.The surface temperature data for June-August during the years of 2010-2018 are from the measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS) products MOD11 C1 with a spatial resolution of 0.05&ordm;&times;0.05&ordm;.<br> This dataset describes the surface temperature of the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>7.&nbsp;Mid-level relative humidity data used are from the ERA5 hourly data on pressure levels of the European Center for Medium Range Weather Forecasting (ECMWF) with a spatial resolution of 0.25&ordm;&times;0.25&ordm;. This dataset describes the mid-level relative humidity of the area around the Sichuan Basin (25&deg;-35&deg;N, 100&deg;-110&deg;E).</p> <p>&nbsp;</p>
