From: First simulations of day-to-day variability of mid-latitude sporadic E layer structures
Comparison between the temporal variations of the \(\hbox {Ca}^+\)profiles of the simulated results and the lidar observations with a height/time resolution of 0.5 km/600 s. The left column shows the simulated results and the right column the lidar observations for 6 nights: December 8, 2015 (a and b), December 18, 2015 (c and d), August 31, 2016 (e and f), December 24, 2014 (g and h), August 21, 2014 (i and j), and September 1, 2016 (k and l)
