Nighttime electron density enhancements at middle and low latitudes in East Asia被引量：2
《Science China Earth Sciences》2015年第4期551-561,共11页ZHANG YanYan LIU LiBo CHEN YiDing LIU Jing YU You LI Ming 
supported by the projects of Chinese Academy of Sciences(Grant No.KZZD-EW-01-3);the National Basic Research Program of China(Grant No.2012CB825604);the National Natural Science Foundation of China(Grant Nos.41231065,41174137,41321003)
Nighttime enhancements in ionospheric electron density at mid- and low-latitudes are investigated by using the critical frequency of the F2-1ayer （foF2） data measured from ionosonde stations at Okinawa （26.3°N, 12...
