Greetings All,

I have placed a patch for the WS Eta on the SOO/STRC ftp server. This
patch is not critical but does fix a number of minor bugs that have
been brought to my attention since the release of 3.1c.  A more detailed
description is provided below.

Also, I have recompiled the WS Eta linux binaries and statically
linked the libraries so that you do not need a separate distribution
for each linux kernel.

If you have any questions let me know.

Bob

PS - Congratulations to Dr. Pablo Santos (SOO, MIA) for 
     successfully defending his dissertation.

WHAT IS IT?

   This patch upgrades version 3.1c of the WS Eta to 3.1d.  


WHAT DOES IT REPLACE?

   There are a bunch of minor bug fixes and error checking to the 
   scripts in the $ETA_SCRIPTS directory.  In addition, there is

   1) A fix to the big endian terrain generation routine.
   2) A fix to the scaling of omega during postprocessing 
      of sigma coordinate data.
   3) The replacement of dcgrib with dcgrib2 for converting the
      grib output into gempak format. The resulting packed files 
      should be ~65% smaller than when using dcgrib.
   4) Increased the number of significant digits in the omega
      field output to the WS Eta BUFR files.
   5) When FTPing model output to AWIPS, the grib files will
      be moved individually as part of separate FTP processes.
      This change will allow the grib decoder to keep up with
      the influx of files and process all the data for viewing.
   6) Some other small stuff I was sweating.


HOW TO INSTALL THE PATCH 

  To install:

	% mv worketa_soostrc_v31c_patch1.tar.gz $WS_ETA
        % cd $WS_ETA

  Installing the patch will overwrite any changes you have made
  to the scripts (eta_download.csh, eta_run.csh, etc.) in the run_time
  directory.  Before continuing with the installation I suggest that
  you save these files for reference:

        % mkdir run_time.orig
        % cp run_time/*.csh  run_time.orig

  Now proceed with the installation

       % zcat worketa_soostrc_v31c_patch1.tar.gz | tar xvf -
    or 
       % tar -xzvf worketa_soostrc_v31c_patch1.tar.gz

  Then

       % eta_clean 3

  Finally, reconfigure the run-time scripts in the $ETA_RUN directory
  using your previously saved settings in run_time.orig.


IF YOU ARE RUNNING THE SOO/STRC BINARIES:

  If you are running a binary distribution of the WS Eta you will need to
  reinstall an updated binary release. Note that with the release of 3.1d
  all linux libraries  have been statically linked so there is no need for
  distributions for each linux kernel. If you have any problems let be know.


LOCALLY COMPILED DISTRIBUTIONS:

  If you are running a locally compiled distribution you will need
  to recompile the model. First edit the $WS_ETA/src/config/dimensions.conf,
  $WS_ETA/src/config/nest_dimensions.conf, and  $WS_ETA/src/config/Makeinc.{OS}
  for your grid dimensions. Then,

       % cd $WS_ETA
       % make clobber
       % make clobber_nest
       % make all
       % make nest
