摘要
利用SROSS-C2卫星数据和IRI - 2016和nrlmsse -00模型模拟数据，分析了1995年- LSA和2000年- HSA期间电离层等离子体温度(电子- T e和离子- T i)和中性温度(T n)的日变化规律。利用SROSS-C2卫星实测数据以及IRI2016和NRLMSIS00的模拟数据，在海拔~500 km、地理纬度~5 ~ 30ºN、地理经度~ 65 ~ 95ºE的印度地区进行了观测。等离子体温度(Te和Ti)表现出相似的日变化特征，而中性温度(Tn)表现出完全不同的日变化特征。在上午时间，te和Ti在LSA和HSA期间表现为早晨超调。夜间增强仅在LSA期间观察到。IRI2016估算的Te和Ti低估了SROSS-C2卫星的测量值。两种模式估计的Tn具有相似的星等值。
BEHAVIOUR OF IONOSPHERIC TEMPERATURES DURING LOW SOLAR ACTIVITY (LSA) AND HIGH SOLAR ACTIVITY (HSA)
- SROSS-C2 satellite data and two modelled data obtained from IRI – 2016 and NRLMSISE-00 models are used to analyze the diurnal behavior of ionospheric plasma temperatures (electron – T e and ion - T i ) and neutral temperature (T n ) during LSA (year – 1995) and HSA (year – 2000). The measured SROSS-C2 satellite data and the modelled data of IRI2016 and NRLMSIS00 was obtained over the Indian region of ~ 5-30ºN geographic latitude and ~ 65-95ºE geographic longitude at an altitude of ~500 km. Plasma temperatures (Te and Ti) show similar diurnal features while the neutral temperature (Tn) shows completely different features. During morning time, T e and Ti exhibit morning overshoot during LSA and HSA. Evening enhancement is observed only during LSA. Te and Ti as estimated by IRI2016 underestimates the measured SROSS-C2 satellite values. The Tn as estimated by both the models have similar magnitude values.
