Quiet time plasmaspheric electric fields and plasmasphere-ionosphere coupling fluxes at L = 2.5
Observations of whistler mode signals from the VLF transmitters NAA and NSS in the Northeast U.S.A., made at Faraday, Antarctica (65°S, 64°W), are used to deduce radial plasma drifts and plasmasphere- ionosphere coupling fluxes near L = 2.5. The fluxes measured represent the sum of the field-aligned...
