Jimmy,

Yes, you can use SNLIST to show what your station lat/lon is for
each time in your file, which likely is the lat/lon of the last
MOB station location- since this upperair file is not a ship file.
Just try dattim = all and area = dset to see what ths SLAT and SLON are.
I suspect they are all the same. At any rate, you can use AREA=dset rather
than @MOB since you only have one station for the DATTIM=0017 time.

A unique station identifier like MOB0001, MOB0002, etc (or MOBhhnn
where hhnn would be the hour and minute of the day) is the best route,
such as is done with dropsones.
