Subject: Now Available: WS Eta Version 3.1h

WHAT IS IT?

   It's a brand new and shinny version of the WS Eta.  I've even
   added that new release smell for those looking for a special
   experience. Workstation Eta 3.1h replaces 3.1g. Imagine that.
   Everything has been doctor tested and mother approved.

   The new release can be found in the worketa/version31h
   directory on the soo/strc ftp server.

WHAT DOES IT FIX?

   For version 3.1h:

   Actually, Version 3.1h consists of minor bug fixes and
   some additional functionality.  Not as much new stuff
   as in previously releases, but I needed to get this version
   out the door so that I can focus on development of the WRF
   package.


   New Functionality

   1) Officially included updated Kain-Fritsch code. The ratio
      or grid scale to convective precipitation will be decreased
      when using the KF cumulus scheme, i.e there will be more
      convective and less gridscale precipitation.

   2) A CASEDATE parameter has been added to the eta_autorun.csh
      script. This option will allow users to execute simulations 
      of historical events  more easily.

   3) You can now create gempak files from both the coarse
      and nested grid model runs.  Everything has been automated.

   4) Added GFS to initialization model data sets.  You just have
      to wait for the changes on the NCEP servers.


   Bug Fixes:

   1) Fixed array dimension problem in model.

   2) Fixed undefined variable used in error message when date
      in grib files does not match requested date.

   3) Fixed archiving of original grib files to directory
      defined in eta_download.csh

   4) Fixed bug in automake section of eta_run.csh

   5) Found workaround for Seg Fault problem in etapost when running
      with 2 CPUs.  Only a problem with PG F90 V5.x

   6) Increased parameter that defines the number of forecast output
      times from 50 to 201.

   7) Some other small stuff I was sweating.


HOW TO INSTALL THE NEW RELEASE

  NOTE:  More detailed instructions are provided on the SOO/STRC
         web site:

     http://strc.comet.ucar.edu/model/wseta_installation.htm

  1) Create worketa31h directory and make link from worketa

     For example:

         % cd /usr1
         % mkdir worketa31h
         % ln -s worketa31h worketa

  2) Download the model distribution files and place them
     in the worketa31h directory

         a. worketa_soostrc_v31h.tar.gz
         b. worketa_sfc_LittleE.tar.gz (for Linux)
         c. worketa_topo.tar.gz

    and for binary users

         d. worketa31h_bin_linux_55x91_2CPU.tar.gz (or another
            binary)

    and if you desire:

         e. install_wseta.csh
         f. wsetadir.tar.gz
         g. worketa_v31h.README

  3) Move all files into the worketa31h directory

  4) Install

      Either:

         % tar -zxvf  worketa_soostrc_v31h.tar.gz
         % tar -zxvf  worketa_sfc_LittleE.tar.gz
         % tar -zxvf  worketa_topo.tar.gz
         % tar -zxvf  binary file .tar.gz

      or

        % ./install_wseta.csh


   5) Log out and back in.

   6) Finally, reconfigure the run-time scripts in the $ETA_RUN
      directory using your previously distribution.

   7) Call me with problems


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_all (same as "make clobber clobber_nest")
       % make all         (same as "make wseta nest")

   or just

       % make everything  (same as "make clobber clobber_nest wseta nest")
