Comparisons of measured and interpolated ion concentrations using the trained long short-term memory (LSTM, a) and the ratio of each ion concentration to total ion concentration (b) from January 12 to April 26, 2018. The letters m and e represent measured and estimated values, respectively. All measured data were used for training or test in cross validation
