Non-migrating diurnal tides in effective neutral temperature and column O/N2 ratio from TIE-GCM

Files containing the non-migrating diurnal tidal amplitudes and phases in effective neutral temperature and column O/N2 ratio as a function of latitude (degrees) during October and January simulated by the TIE-GCM model. O/N2 amplitudes are reported as percent relative to the zonal mean. Temperature amplitudes are in units of Kelvin. Phases are reported as the universal time of maximum at 0º longitude. An additional file is provided reporting the contribution function as a function of altitude (km) for nadir viewing (emission angle equal to 0º) and solar zenith angle equal to 70º. The contribution function, provided by Computational Physics, Inc., weights the neutral temperature profiles used to derive the tides. The vertical column O/N2 ratio is computed relative to a standard reference N2 depth of 1017 cm-2 .本数据集包含由TIE-GCM模型模拟的10月与1月期间，有效中性温度（effective neutral temperature）与柱体O/N₂比值（column O/N₂ ratio）的非迁移周日潮汐（non-migrating diurnal tide）振幅与相位，上述参数随纬度（单位：度）变化。其中O/N₂振幅以相对于纬向平均（zonal mean）的百分比形式给出，温度振幅单位为开尔文，相位以0°经度处达到极值的世界时（universal time）进行表征。额外提供了一份配套文件，其中包含针对天底观测（nadir viewing，发射角为0°）且太阳天顶角（solar zenith angle）为70°时，随高度（单位：千米）变化的贡献函数（contribution function）。该贡献函数由Computational Physics, Inc.（计算物理公司）提供，用于对推导潮汐所用的中性温度廓线（neutral temperature profiles）进行加权运算。本次研究中的垂直柱体O/N₂比值以10¹⁷ cm⁻²的标准参考N₂柱量为基准完成计算。
