ETA Data support

[jrperkin at COASTAL.EDU]

Dear ARPS support,

Recently I inquired about using ETA data in EXT2ARPS.  I retrieved the
ETA files from ftpprd.ncep.noaa.gov, and mirrored what you did at
http://www.caps.ou.edu/wx/p/r/conus/wrf, yet was unable to create my own
initial condition.  The error I recieved in my ext2arps output file
was "No 3-D variable was found in the GRIB file." However, there is data
in the file, and the file was found.  What might be causing this?

Also, with my previous inquiry, I recieved two replys.  One from Kevin
Thomas and one from Yunheng Wang.  Yunheng Wang said I needed to have ARPS5.1.3
(of which I am running version 5.0.0) and to read the comments for
subroutine getnmceta218 for brief instructions on using ETA.  Kevin Thomas,
however, did not say I needed version 5.1.3.  Before, when using the ARPS
sample data, I was able to get ETA data read in correctly using my current
version of ARPS. Is this still the case, or should I upgrade?

Thanks in advance,
Jim Perkins
