Illustration of the large sensitivity of ion admittance to small variations in light ion composition. The point at lower right is the theoretical admittance for the Swarm A dayside ascending overflight of the Jicamarca incoherent scatter radar facility, using the radar estimates for electron density and temperature and IRI estimates for ion composition. An increase to 3.5% H + with concomitant decrease to 94.9% O + (upper left point) decreases the ion admittance by almost 2 nA/V
