a
TS1 is the MOZART‐TS1 mechanism (Emmons et al., 2020) and TS2.1 is the MOZART‐TS2.1 mechanism (Hodzic et al., 2016; Jo et al., 2021; Schwantes et al., 2020).
b
ne30 = ∼111 km globally uniform resolution and ne0conus30 × 8 = ∼111 km global resolution with mesh refinement down to ∼14 km over the conterminous US (CONUS).
c
Average horizontal resolution over CONUS for the selected grid.
d
Specified dynamics (SD) relaxation time.
e
Months simulated in year 2013.
f
No nudging over CONUS, but a 50‐hr relaxation time everywhere else.
