dc.description | We deduce the cold electron plasma density from NASA Van Allen Probes measurements throughout 2012-2019. We then extract two of the plasmasphere boundaries. We first use the gradient method for locating the plasmapause at L pp and, then, the 100 cm−3 density threshold for the plasmasphere outer edge located at L 100 . The sharp gradient of the plasmapause is only defined in 53% of cases, while L 100 is defined for ∼85% of cases. Differences and similarities between L pp and L 100 are discussed. L 100 is demonstrated to bound the plasmasphere at large L-shell in the dusk where L pp gradients often lack. We generate new empirical density models of the plasmasphere boundaries binned by L-shell, magnetic local time (MLT), and the maximum of the Kp index over 24 hours (Kp*). | |
