history_interval error in WRF v4.2

[HHidalgo]

Hello everyone,

I'm trying to run a simulation with data written every 10 minutes (history_interval = 10), but the program skips the statement and writes the results every 60 minutes. What can be caused this?

&time_control
run_days = 0,
run_hours = 36,
run_minutes = 0,
run_seconds = 0,
start_year = 2023,
start_month = 11,
start_day = 22,
start_hour = 00,
start_minute = 00,
start_second = 00,
end_year = 2023,
end_month = 12,
end_day = 02,
end_hour = 00,
end_minute = 00,
end_second = 00,
interval_seconds = 10800,
input_from_file = .true.,
history_interval = 10,
frames_per_outfile = 1000,
restart = .true.,
restart_interval = 1440,
io_form_history = 2,
io_form_restart = 2,
io_form_input = 2,
io_form_boundary = 2,
write_hist_at_0h_rst =.true.,
debug_level = 0,

This might help.

From the WRF users guide:

history_interval
Frequency (in simulation minutes) that data are written/recorded to history output file(s) (wrfout_d0); can also use history_interval_d, history_interval_h, history_interval_m, history_interval_s, alternatively to set the frequency in days, hours, mins, secs, respectfully

Hi William,

I've tried using the alternatives the manual mentions (history_interval_m=10, history_interval_s=3600), but the model still writes results every 60 minutes. My time step is 15 seconds, so I rule out that being the problem.

Please add the option below to your namelist.input (&time_control)

override_restart_timers = .true.'

This will change the alarms from what is previously set.

I believe this will fix your problem. However, let me know if you still have the same issue.
