【摘要】 利用高层大气辐射传输代码SHARC中的极光模式模拟并分析了CO₂ 4.3μm和15μm两个重要红外谱带的极光辐射特性。模拟结果表明,两个带的临边辐射都会在极光事件开始后随时间演化,并缓慢地增强到稳态;4.3μm带辐射在极光事件中相比静态辐射显著增强而15μm带辐射受增强的效应不明显,4.3μm带的稳态极光辐射可与白天情形相比拟。在极光区域内,极光效应会随高度的降低而减弱。更多还原

【Abstract】 Using auroral model from high-altitude atmospheric radiative transfer code SHARC simulated and analyzed CO₂ 4.3μm and 15μm bands’ radiation characteristics under auroral condition. The results show that two bands’ limb radiance will be enhanced gradually and slowly to a steady state after auroral electron are dosed. 4.3μm band’s radiation is enhanced so heavily that its steady state’s radiance can reach the level of day condition’s, while 15μm band’s radiation is still near to its quiescent condition’s. Besides, in the auroral area, auroral effects fade by altitude lowering.更多还原
