2009年6至7月华南地区电离层TEC扰动研究
Study of the South China Ionospheric TEC Disturbances During June-July 2009
摘要
Abstract
There are many origins of ionospheric TEC （Total Electron Content） disturbances during June-July 2009, including several earthquakes and a total solar eclipse. In current study, using the GFS-TEC date observed during June-July 2009 in Guangzhou GPS station and processed by a sliding window with the data of prior 15 days, the characters of South China ionosphere are investigated in spatial and temporal distribution. The results indicate that there are possible relations between the South China ionospheric TEC disturbances and seismic-activities as well as total solar eclipse during June-July 2009. The characters of ionospheric TEC disturbance induced by several earthquakes are commented as follows： positive values before earthquake, positive values or negative values near and after the occurrence of earthquake, even more, that the positive values on the day of total solar eclipse （22 July 2009） may be accounted for magnetic activities, seismic activities and total solar eclipse.关键词
