Here are the data description

ON2r213nw, ON2r214nw, ON2r215nw, ON2r216nw: TIEGCM simulated column density ratio of O to N2 on DOY 213-216 with real IMF in 2021. The array dimensions are 288*144*96, 288 stands for longitude numbers from -180 to 180 in a resolution of 1.25. 144stands for latitude numbers from -88.75 to 88.75 in a resolution of 1.25. 96 stands for times, from 0:10 UT to 23:55 UT in a 15 minutes resolution.

ON2r 214nw0byn stands for O/N2 without IMF By. same dimension as aboved ON2

files with name UN, VN are zonal and meridonal winds near 160 km simulated by TIEGCM, same dimensions as ON2.

以下为该数据集的详细说明

ON2r213nw、ON2r214nw、ON2r215nw、ON2r216nw：为2021年日历年积日（Day of Year, DOY）213至216日，采用实际行星际磁场（Interplanetary Magnetic Field, IMF）条件下，由TIEGCM模拟得到的O与N₂的柱密度比值。该数据集的数组维度为288×144×96：其中288代表经度格点数，经度范围为-180°至180°，空间分辨率为1.25°；144代表纬度格点数，纬度范围为-88.75°至88.75°，空间分辨率为1.25°；96代表时间步数，时间覆盖世界时（Universal Time, UT）0:10至23:55，时间间隔为15分钟。

ON2r214nw0byn代表未施加IMF By分量时的O/N₂柱密度比值，其维度与前述ON2系列文件一致。

命名为UN、VN的文件为TIEGCM模拟得到的160公里高度附近的纬向风与经向风，其维度与ON2系列文件相同。
