英文摘要: We statistically examined the plasmapause location (Lpp) under quiet geomagnetic conditions (Kp ≤ 1) using the electron density inferred from the Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft potential for 2 year period (2008 and 2009). Five hundred forty-three Lpp samples were identified under steady quiet conditions with Kp values ≤ 1 during 12 h prior to the plasmapause crossing. From our large data set, we determined the medians and means of Lpp in L and magnetic local time (MLT). They are located near geosynchronous orbit and nearly circular. The Lpp medians show a slight bulge located in postdusk sector. Comparing with previous models, our median or mean Lpp is extended 1-2 L from the Earth than the model Lpp along the local time from 0800 to 2400 MLT. That is, Lpp locations in the previous models are underestimated during quiet geomagnetic conditions. © 2015 American Geophysical Union. All Rights Reserved.
