Fig. 5From: Ionospheric responses to the 21 August 2017 solar eclipse by using data assimilation approachThe spacial perturbations between the eclipse day and the previous day at 1830 UT and 110 km altitude. There are a Pedersen conductivity, b eastward electric field, and c meridional wind effect (\( \overset{\rightharpoonup }{U}\times \overset{\rightharpoonup }{B} \)) in the eastward directionBack to article page
