| Abstract | 利用天宫一号的轨道大气环境探测器在2012年12月7日至2013年1月4日,地磁活动平静下的大气密度探测数据,与NRLMSISE-OO和JB2008模式进行比较。与实测数据相比,NRLMSISE-00模式整体高估11.6%,而JB2008整体低估9. 8%。JB2008模式在逐日变化趋势方面与实测结果更吻合,更好地反映了太阳辐射对热层大气的影响;而NRLMSISE-00在平静期间地磁活动影响大气密度的变化特征上,比JB2008更符合实测结果。实测结果显示冬季半球日峰值出现时间比夏季半球早,JB2008与实测相符,NRLMSISE-00则与实测相反。整体而言,在天宫一号轨道高度、地磁平静期,JB2008模式优于NRLMSISE-00模式。 |
| Other Abstract | Based on thermosphere density data from TianGong-1 form Dec. 7 2012 to Jan. 4 2013, when geomagnetic index was low,comparison between observed data and thermospheric model including NRLMSISE-00 and JB2008 were made. The major results were as follows : the NRLMSISE-00 model overestimated the observed data by about 11.6%. JB2008 model underestimated the observed data by about 9. 8%. During low geomagnetic activity, ap index used in NRLMSISE-00 was more close to the observed data variation than that of DCT index used in JB2008 ; JB2008 was good at daily variation. On LT-latitude variation JB2008 could capture the main characteristics, while NRLMSISE-00 was almost the opposite. Therefore JB2008 was better than NRLMSISE-00 at TianGong-1 altitude. |
