Empirical Model of Thermospheric NO cooling Based on SABER observation

This thermospheric NO cooling model is deverived from SABER observation within 100-280 km altitude. The vertical structure is derived from PCA method and the horizontal distribution is reconstruced by the consequence nonlinear regression technic.本热层一氧化氮（NO）冷却模型源自100~280千米高度范围内的SABER观测数据。其垂直结构通过主成分分析（PCA）方法构建，水平分布则借助后续非线性回归技术完成重构。
