Simulated (Sim) versus observed (Obs) LAI of paddy rice using the RF and DNN regressors for (a–d) Cheorwon, (e–h) Paju, (i–l) Gimje, South Korea, and (m–p) Pyeongyang, North Korea in (a, e, i, and m) 2014, (b, f, j, and n) 2015, (c, g, k, and o) 2016, and (d, h, l, and p) 2017. ME-RF and ME-DNN represent the model efficiency of RF and the model efficiency of DNN.
