Materials for "Dependence of Neutralized Charge Amount on Meteorological Conditions in Summertime Lightning Discharges in Japan"
Description
# About This data repository contains the data and materials used in Iwai et al., "Dependence of Neutralized Charge Amount on Meteorological Conditions in Summertime Lightning Discharges in Japan" (submitted to Journal of Geophysical Research: Atmospheres). If you have any questions or comments, please contact the corresponding author. # Datasets This repository includes the following datasets: EFM_data.tar : the neutralized charge amount estimated from ground-based electric field measurements File name : EFM_mmdd.csv Data format : CSV Note : The first column represents time in seconds since 00:00 (JST) on the date indicated by 'mmdd' in the file name. The second column represents the amount of neutralized charge (C). EFM_data_random.tar : the neutralized charge amount estimated from ground-based electric field measurements while accounting for uncertainty in lightning location determination File name : EFM_mmdd_random.csv Data format : CSV Note : The first column represents time in seconds since 00:00 (JST) on the date indicated by 'mmdd' in the file name. The second column represents the amount of neutralized charge (C). scale_data_2d.tar.gz : numerical simulation outputs generated using the Scalable Computing for Advanced Library and Environment (SCALE) model (two dimensional variables) File names : scale_yyyymmdd+36h_2d.nc.tar.bz2, scale_yyyymmdd+48h_2d.nc .tar.bz2 Data format : NetCDF Note : Due to limitations on the maximum uploadable file size, only data covering a 6-hour period starting 10 hours after the beginning of the simulation are provided in this repository. scale_data_3d : numerical simulation outputs generated using the Scalable Computing for Advanced Library and Environment (SCALE) model (three dimensional variables) File names : scale_yyyymmdd+36h_3d.nc.tar.bz2, scale_yyyymmdd+48h_3d.nc.tar.bz2 Data format : NetCDF Note : Due to limitations on the maximum uploadable file size, only data covering a 6-hour period starting 10 hours after the beginning of the simulation are provided in this repository. MSM.tar : MANL-derived two-dimensional composite fields of 500-hPa geopotential height and mean sea-level pressure (MSLP) for the F and U categories File names : 500hPa_geo_F_category.npz, 500hPa_geo_U_category.npz, MSLP_F_category.npz, MSLP_U_category.npz Data format : NumPy compressed archive (.npz) Note : These files contain the category-mean two-dimensional fields used to analyze the synoptic environments of the F and U categories. # Contact Naota Iwai Graduate School of Engineering, The University of Osaka Email: naota.iwai[at]civil.eng.osaka-u.ac.jp
