چکیده انگلیسی
In this study we compare Ï estimated from magnetometer data at two stations in the CPMN (Circum-pan Pacific Magnetometer Network) chain, Tixie (TIK, geographic coordinates: 71.59°N, 128.78°E, L=6.05) and Chokurdakh (CHD, geographic coordinates: 70.62°N, 147.89°E, L=5.61), with the plasma electron number density (Ne) observed by the WHISPER (Waves of HIgh frequency Sounder for Probing the Electron density by Relaxation) instrument onboard the Cluster satellites. For the interval of January 1, 2001-December 31, 2005, we have identified 19 events in which the Cluster spacecraft were located on the field line running through the midpoint of TIK and CHD when they observed FLR, and statistically compared the simultaneously observed Ï and Ne, although the number of events are limited (19). In 15 out of the 19 events the ratio of Ï to Ne falls into a realistic range. It is also suggested that the contribution of heavy ions tends to increase when the magnetosphere is disturbed.
