This test is to confirm if changing the timestep but keeping the same spatial resolution makes a difference to the model state. Ideally - it should not.

KEYWORDS
1deg, ne30, WACCM, 135L, tag cam6_4_028, derecho, cam7 physics
DESCRIPTION
1 degree SE WACCM 5 day test with dt=3.75 min to test if anything is changed to the model. E.g. in WACCM-RR paper, outside the CONUS region, both RR and Non-RR models have 1-degree resolution, but Non-RR has 30 min timestep and RR has 3.75 min timestep. There are global changes seen in the model, so I want to know what's up.

Need to see what timesteps have been chosen for the RR model - although it should be enough to just test the main timestep - the physics timestep, right? Everything else changes as a consequence anyway.
