Using Swarm A data, the figure illustrates the estimated peak of AEJ positions using the SLC and LC methods for the Northern Hemisphere over four days starting from 13 March 2019. The second and third rows show the peak of AEJ positions for ascending and descending orbits, respectively. The first row represents the time variations of SME, SMU, and SML. The fourth row displays the time series of AEJ calculated using the SLC method compared to SME.
