From: Response of plant reflectance spectrum to simulated dust deposition and its estimation model

Three edge parameters of leaf spectrum under the influence of different dust retention amounts. (A) red edge position, (B) blue edge position, (C) yellow edge position, (D) red edge slope, (E) blue edge slope, (F) yellow edge slope. T1–T6 represent different dust retention amounts (Coal dust: T1-0.1139, T2-0.1596, T3-0.2366, T4-0.2674, T5-0.2863, T6-0.3453 g m−2; Cement dust: T1-0.1047, T2-0.1420, T3-0.1836, T4-0.2294, T5-0.2693, T6-0.3477 g m−2; Pure soil dust: T1-0.0372, T2-0.0977, T3-0.1371, T4-0.1798, T5-0.2208, T6-0.2624 g m−2).
