Data files for submission 'Electron Scattering, Transport and Energization by Alfvénic Turbulence in Earth’s Outer Radiation Belt' by C. C. Chaston to Geophysical Research Letters

File Description 1. Wave file: ‘flr_torpol_100_krhoi_01_10_f1.txt’ The file contains the location, plasma parameters and unscaled amplitude quantities for each of the 100 mode solutions at each point along the geomagnetic field at L=5.7 . The header within the file describes the content and format. 2. Particle Files: ‘electron_b_specf1_100_500kev_pa45_2_neg_vz.txt’ For a 500 keV electron with initial equatorial pitch-angle of 45 degrees. Each row of the file contains the time (seconds), location of the particle (Earth_radii, radians; r, theta, phi), its velocity (m/s; v_r, v_theta, v_phi) and the electric (V/m; E_r, E_theta, E_phi) and magnetic fields (T; b_r, b_theta, b_phi) at that location in spherical coordinates and in the following order: time, r, theta, phi, v_r, v_theta, v_phi, E_r, E_theta, E_phi, b_r, b_theta, b_phi There is a file for each energy and pitch angle considered with sizes ranging from 3.3 GB up to 7 GB and totaling over 200 GB. Given the size of these data files only that used to produce Figure 2 and the corresponding parts of Figure 3 is supplied. The others are available on request. 3. Diffusion files: ‘diffusion_coeffs_d[quantity]_[eq_pitch_angle]_[bounces]_2.txt’ Derived from the particle files. The filename indicates the quantity considered [L, theta, or scalar momentum] the initial pitch-angle at the equator in degrees and the number of bounces over which the distribution of shifts is evaluated. Each file is comprised of three columns and 9 rows. The columns are energy in keV, the width of the Gaussian fits to the distribution of shifts in the quantity considered, and the diffusion coefficient defined as described in the text. Each row provides these results at energies from 50 keV to 5 MeV as identified by the entries in the first column. L is unitless, theta is in degrees, and momentum is in kgms-1.

### 数据集说明
1. 波场数据文件：`'flr_torpol_100_krhoi_01_10_f1.txt'`
该文件存储了L=5.7处沿地磁场（geomagnetic field）各空间节点的100组模式解的位置、等离子体参数（plasma parameters）及未标定幅度的量化物理量信息。文件内的头部信息已对内容与格式进行详细说明。

2. 粒子追踪数据文件：`'electron_b_specf1_100_500kev_pa45_2_neg_vz.txt'`
该文件针对初始赤道投掷角（equatorial pitch-angle）为45度的500 keV电子生成。文件每行依次存储以下参数：时间（单位：秒）、粒子位置（以地球半径（Earth_radii）为单位的径向距离r、极角θ、方位角φ，单位分别为地球半径、弧度）、速度（单位：米/秒，包含径向速度v_r、极向速度v_θ、方位向速度v_φ），以及该位置处的电场（electric fields，单位：V/m，即E_r、E_θ、E_φ）与磁场（magnetic fields，单位：特斯拉T，即b_r、b_θ、b_φ），坐标系采用球坐标系（spherical coordinates），各参数的排列顺序为：时间、r、θ、φ、v_r、v_θ、v_φ、E_r、E_θ、E_φ、b_r、b_θ、b_φ。
本数据集涵盖所有研究涉及的能量与投掷角对应的粒子文件，单文件体积介于3.3 GB至7 GB之间，总容量超过200 GB。鉴于数据文件体量较大，本次仅提供用于生成图2及图3对应部分的数据文件，其余文件可按需申请获取。

3. 扩散系数文件：`'diffusion_coeffs_d[quantity]_[eq_pitch_angle]_[bounces]_2.txt'`
该类文件由粒子追踪数据文件推导得到。文件名各字段的含义如下：`[quantity]`表示所研究的物理量（可选值为L、θ或标量动量（scalar momentum）），`[eq_pitch_angle]`为初始赤道投掷角（单位：度），`[bounces]`为用于评估位移分布的反弹次数。
每个文件包含3列数据与9行记录：第一列为能量（单位：千电子伏keV），覆盖50 keV至5 MeV的区间；第二列为针对所研究物理量的位移分布进行高斯拟合（Gaussian fits）所得的宽度；第三列为扩散系数（diffusion coefficient），其具体定义详见正文。各物理量的单位分别为：L无量纲，θ以度为单位，动量以kg·m·s⁻¹为单位。
