Fig. 2From: Longitudinal structure in electron density at mid-latitudes: upward-propagating tidal effects(Top) Longitudinal and magnetic local time variations of the electron density (\(\Delta Ne\)) with migrating tides inputs at the low boundary of TIEGCM (base run). (Bottom) Residual \(\Delta Ne\) (\(\delta \Delta Ne\)) driven by migrating tides, which is the difference between \(\Delta Ne\) with and without tidal inputs. Densities are given in \(10^{10}\,\mathrm{m}^{-3}\) Back to article page
