Materials for "Faint-class Downward Terrestrial Gamma-ray Flash Produced by Downward Negative Leader of Winter Lightning Flash"

# Materials for "Faint-class Downward Terrestrial Gamma-ray Flash Produced by Downward Negative Leader of Winter Lightning Flash" ## About This data repository contains data and materials used for Wada et al. "Faint-class Downward Terrestrial Gamma-ray Flash Produced by Downward Negative Leader of Winter Lightning Flash", submitted to Journal of Geophysical Research: Atmospheres. If you have any questions or comments, please contact the corresponding author of the paper. ## Datasets Data are provided in the CSV, NPZ, or PNG format. NPZ is a data format readable with Python. There are two NPZ files for simulation data.Both files contain matrices named "fluence", "x_edge", "y_edge", "energy_hist", and "energy_edge". The "fluence", "x_edge", and "y_edge" matrices are for the gamma-ray fluence distribution. The X and Y axes are longitude and latitude, respectively. The "energy_hist" and "energy_edge" matrices are for the energy spectrum of seed electrons (seen the paper). ## Contact Yuuki Wada (Faculty of Science, Hokkaido University) wada (at) yuuki-wd.space# 《冬季闪电下行负先导（Downward Negative Leader）引发的微弱级下行地面γ射线闪光（Terrestrial Gamma-ray Flash）》配套研究资料 ## 关于 本数据集仓库收录了Wada团队提交至《地球物理研究杂志：大气》（Journal of Geophysical Research: Atmospheres）的同名论文所用的全部数据与研究资料。若您有任何疑问或建议，请联系该论文的通讯作者。 ## 数据集 本数据集提供CSV、NPZ及PNG格式的文件。其中NPZ是可通过Python读取的数据格式。 本次模拟数据包含两份NPZ格式文件，两份文件均包含名为`fluence`、`x_edge`、`y_edge`、`energy_hist`及`energy_edge`的矩阵。其中`fluence`、`x_edge`与`y_edge`矩阵对应γ射线通量分布，X轴与Y轴分别代表经度与纬度；`energy_hist`与`energy_edge`矩阵对应初始电子的能谱分布（详细说明请参见论文）。 ## 联系方式 和田悠希（Yuuki Wada），北海道大学理学院 邮箱：wada（at）yuuki-wd.space
