Re: 20041013: 20041012: 20041012: ACARS



Chiz,

I am revisiting this problem as we are still not getting the 
ACARS data written to the GEMPAK format.  At least now I have
a log file for acars and it looks like this

Oct 19 18:51:06 dcacars[1655]: Could not open gempak/acars/.tmp_netcdf.r0p5bw

I am not sure why I get these messages.  The gempak acars directory has the
same permissions as all the other data directories.  I don't know why the
ldm can't write to it.
