Global observations of CSES in a–d Ne/Ni and e–h Te/Ti at 14:00 LT and 02:00 LT in August 2018. The red star denotes the epicenter of the 5 August 2018 M7.0 earthquake. CSES data were first grided into 5183 lattices with a lattice size of 2.5° by 5° in latitude by longitude. The median value of each lattice is computed, and the medians are smoothed for the global map by a window of 5-lattice by 5-lattice sliding by 1-lattice in the latitudinal and longitudinal directions
