  1. Distances (km) between observed and ensemble mean ETC and IVT center trajectories during the analysis period are provided for three domains (D1, D2, and D3) together with their differences between ON and OFF experiments (ON – OFF). Refer to Fig. 5 for the error distance distribution across ensemble members.
