Hi Mike,
We're not seeing any issues with our feed or execution of goes-restitch.
I'm actually seeing TISU as Mesoscale-2 right now, with Mesoscale-1 under
TISH. Regardless, no anomalous behavior with what we're running.
Are you seeing anything in the logs from the script itself? (i.e.
/home/ldm/var/logs/goes-restitch/SU.log)
For the Mesoscale sectors, goes-restitch isn't doing much, since the
sectors are generally only one tile (they are today). All that's happening
is removing WMO header/footer and adjusting a bit of netCDF metadata.
The first place I'd look, then, is to see if something's going wrong with
/home/scripts/sat/goes_mcidas/manager.py.
