低纬地区L波段电离层闪烁预报方法
A prediction method of L-band ionospheric scintillations in low latitude regions
摘要
Abstract
In order to achieve the prediction of L-band ionospheric scintillations and according to the physical mechanism of L-band ionospheric scintillations generation in low latitude regions,the method is proposed to predict the occurrence of L-band ionospheric scintillations in low latitude regions according to the fact that the plasma irregularities detects in ionospheric F layer over the magnetic equator.In order to investigate the feasibility of the method,C/NOFS satellite observations and L-band ionospheric scintillations data recorded at Sanya (geographic coordinates:18.3°N,109.6°E;geomagnetic latitude:8. 27°N),Shenzhen (geographic coordinates:22.59°N,113.97°E;geomagnetic latitude:12.59°N)and Guilin (geographic coordinates:25.29°N,110.33°E;geomagnetic latitude:15.23°N)in October 2011 have been analyzed.The results show that this prediction method has a high accuracy in predicting L-band ionospheric scintillations in lower latitude regions (namely,Sanya and Shenzhen),but it has a low accuracy in forecasting L-band ionospheric scintillations at the region near the crest of equatorial anomaly (i.e.,Guilin).关键词
