Fig. 3: Spatial distribution of RMSE differences (TransNet - AGATNet) at 170 stations across South Korea.

a Shows +1 h lead time, panel (b) shows +6 h, panel (c) shows +24 h, panel (d) shows +48 h, and panel (e) shows +72 h. Each station is represented by a filled circle, with colors indicating RMSE difference in μg/m3 according to the vertical color bar. Blue circles indicate lower RMSE for TransNet (negative difference), while red circles indicate lower RMSE for AGATNet (positive difference). White circles indicate negligible difference. The color scale ranges from −8 μg/m3 (dark blue) to +8 μg/m3 (dark red).
