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.以下为数据集ON2r213nw、ON2r214nw、ON2r215nw、ON2r216nw的描述：本数据集为2021年日历年积日（Day of Year, DOY）213至216、采用真实行星际磁场（Interplanetary Magnetic Field, IMF）条件下，热层-电离层-中层环流模型（Thermosphere Ionosphere Mesosphere Electrodynamics General Circulation Model, 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，时间覆盖范围为世界时（Universal Time, UT）0:10至23:55，时间分辨率为15分钟。ON2r 214nw0byn代表未施加IMF By分量时的O/N₂比值，其数组维度与前述ON2系列数据集一致。此外，命名为UN、VN的数据集为TIEGCM模拟得到的160km高度附近的纬向风与经向风，其数组维度与前述ON2系列数据集相同。
