Ion distribution functions
Ion distribution functions observed by the THEMIS P1 probe at the end of the growth phase of the February 26 substorm (see Angelopoulos et al., Science, 2008) and calculated using the Sitnov et al. (2006) model. The dashed white line in the right-hand side plot indicates the boundary between gyrating and meandering particles.
This result was presented by X.-Z. Zhou et al. at the First Joint Cluster-THEMIS workshop, held 23-26 September 2008 at the University of New Hampshire, Durham, USA.Last Update: 1 September 2019
