Wind 3DP EESA-LOW Electron Pitch-Angle Distributions

Wind 3DP electron pitch angle product providing electron fluxes in 8 directional bins relative to the local magnetic field direction at 15 different energy levels. Time resolution is mode- dependent, with 96s being used for the past several years and with higher resolution (e.g., 24s) used for some earlier intervals. For any given cadence, electron observations made over the full cadence interval and in all look directions in and out of the spacecraft spin plane, are folded together with the magnetic field vector as averaged over the cadence interval, to produce the pitch angle distributions. The data are calibrated science quality data.

Wind 3DP电子俯仰角数据集产品可提供15种不同能量能级下、相对于局地磁场方向的8个方向扇区的电子通量。该数据集的时间分辨率取决于观测模式：近数年采用96秒的时间分辨率，部分早期时段则采用更高的分辨率（如24秒）。对于任意给定的采样周期，将完整采样周期内、航天器自旋平面内外所有观测视向获取的电子观测数据，与该周期内平均得到的磁场矢量进行整合处理，即可生成电子俯仰角分布。本数据集为经过校准的科学级观测数据。
