MAVEN DD2 Martian background atmosphere

The structure of the Martian background atmosphere from 80 km to 500 km appropriate for moderate solar activity and subsolar conditions, constructed to be consistent with the MAVEN Neutral Gas and Ion Mass Spectrometer measurements of CO2, O, N2, CO, and Ar. File format: Col #1 - Altitude in km; Col 2 to 5 - CO2, O, N2, CO, and Ar densities in cm^-3; Col 6 - Eddy diffusion coefficient in cm^2 s^-1; Col 7 - Neutral temperature in K.适用于中等太阳活动及日下点条件、高度范围为80 km至500 km的火星背景大气结构，其构建与MAVEN中性气体与离子质谱仪针对CO₂、O、N₂、CO及Ar的测量结果保持一致。文件格式说明：第1列为高度（单位：km）；第2至5列为CO₂、O、N₂、CO及Ar的数密度（单位：cm⁻³）；第6列为涡流扩散系数（单位：cm²·s⁻¹）；第7列为中性大气温度（单位：K）。
