MINPA ion background statistic from 2021-11 to 2022-11

Mars ion and neutral particle analyzer (MINPA) is one of the three scientific payloads onboard Tianwen-1. This dataset uses MINPA ion detection data from November 2021 to November 2022 to obtain the distribution of ion background as a function of azimuthal sectors and polar angle channels. The data are generated using MATLAB and saved in .mat format, which can be read with MATLAB. The file contains the following variables: time (time information), bg_H_azi (H ion background distribution along the azimuthal angle), and bg_H_pl (H ion background distribution along the polar angle).
