Dear Colleagues,

I ran same cases with the only difference:
use_adaptive_time_step = .true.
use_adaptive_time_step = .false.

But the results are different, please see the attached files. Could you please kindly let me know the reason for this?

Best wishes,
Stella

Stella,
We don't expect the same results when running a simulation with adaptive time step turned on, versus turned off. Because the model is integrating at different time step intervals, the results will be different.
