Abstract风云二号卫星是我国研制的第一代静止业务气象卫星.本文针对风云二号C星/D星(FY-2C/D)太阳X射线探测数据与美国GOES系列卫星太阳X射线探测数据开展交叉比对,以检验FY-2C/D卫星数据的有效性.研究结果表明在X射线通量变化的时间特性以及通量大小等方面,FY-2C/D卫星探测结果与GOES系列卫星探测结果具有较好的一致性.对2004年11月2010年6月期间85次耀斑事件X射线峰值流量的比对结果表明,FY-2C卫星与GOES系列卫星的探测结果在1~8A波段的相关系数为0.795,FY-2D卫星与GOES系列卫星的探测结果在0.5~3A和1~8A波段的相关系数分别为0.921和0.989,说明FY-2C/D卫星太阳X射线探测结果可信度较高,能够用于太阳X射线耀斑的监测、预警以及研究工作.
Other AbstractFengyun 2(FY-2) satellite is the first generation of geostationary meteorological satellite of China.The solar X-ray detector aboard on the FY-2C/D satellite has the capability to observe the solar X-ray flux of >5.18 keV and >3.27 keV,respectively.For the purpose of examining the effectiveness of the FY-2C/D satellite X-ray data,we compare them with the similar data of the GOES satellites,and find that these two categories of data fit well in the temporal characters and X-ray flux during solar flare events.By the cross comparison of the X-ray peak flux for 85 solar flare events from November 2004 to June 2010,it is found that the linear correlation coefficient is 0.795 between the data of FY-2C and GOES satellites in 1~8A, and the corresponding coefficients are 0.921 and 0.989 between the data of FY-2D and GOES satellites in 0.5~3A and 1~8A. The results indicate that the quality of FY-2C/D satellite solar X-ray data is quite well for the monitoring,warning and research of the solar X-ray flare events.
