Hi Houjun and Weiyu,

here is the failed run Bob tried with the 1hr restart compset that we 
discussed during our meeting:


We would really appreciate it if you could kindly give us any suggestions.

Hi Naomi,

    I originally started with a 1hr run, but when I tried to do a 1hr 
run with the WAM restart interval set to 1hr, the run stopped almost 
immediately. Valery speculated that maybe WAM won’t work with that short 
of a restart interval (he said that he’s never tried it and maybe it 
causes a problem with the digital filters), so I switched to the 1day 
run, where it at least ran for 18 hours.

If you’re curious here’s that 1hr run:

If you see anything that I should change, let me know. I’m happy to try 
that run again.
