Date: Wed, 20 Aug 2003 15:15:20 -0600 (MDT) From: Bob Rozumalski Subject: Now Available: WS Eta Version 3.1g 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 3.1g replaces the never officially released version 3.1f.beta, which replaced version 3.1e. Everything has been doctor tested and mother approved. The new release can be found in the worketa/version31g directory on the soo/strc ftp server. WHAT DOES IT FIX? For version 3.1g: 1) You may now specify different data sets for the initial and boundary conditions. For example, using the 12km Eta tiles for the initial conditions and 32km tiles for the lateral boundaries. Also included in the package is the ability to ingest local LAPS analyses in grib format. That's correct, you will soon be able to initialize your runs with LAPS grids, just like WFO MIA is currently doing. 2) There are 2 new fields available. LFC-3000m AGL CAPE and LFC (agl m). Also, the existing CAPE and CINS calculations are now derived from 0-90mb above ground layer just like the operational model. Previously it was 0-180mb above ground layer. Thanks to Rich Naistat for requesting the fields. 3) More efficient grib file downloading. This change will hopefully eliminate the premature termination of the ftp connection when downloading grib files from the NCEP and STRC servers. 4) The download script now checks the date on the existing surface files on the local machine before trying to download duplicate files. Thanks to George Phillips for making the suggestion. 5) Major bug fixed in the model surface scheme. 6) Fix to the horizontal advection scheme that will hopefully reduce the number of model run terminations. 7) Bug fixes to the BUFR file generation scripts to fix problem when outputting hourly forecasts but accumulating precip every 3 hours. Also fixed problem with BUFR precip values 1/10th that of grib files. 8) New arguments to the "make" command for those with a compiler. 9) Lots of other stuff that I can't remember at this moment. There are a few minor bug fixes and error checking to the scripts in the $ETA_SCRIPTS directory. Furthermore, from the never officially released 3.1f: 10) The ability to send a subset of the forecast output to AWIPS via RCP, FTP, and (now) CP. If you are creating 1-hourly forecasts for BUFR file generation you can now send 3-hourly forecasts to AWIPS and GEMPAK. 11) A modified version of wgrib is now provided to allow users to inspect the contents of the WS Eta grib files. A "-W" argument has been added to compute and display the grid navigation information. Replaces the use of the gempak routine "gdinfo". You will now get valuable information like: WS Eta GRID NAVIGATION INFORMATION FOR AWIPS Lambert Conic Conformal Projection Grid Center : 40.000, -105.500 Lower Left (SW) Corner : 37.748, -108.720 Upper Right (NE) Corner : 42.139, -101.813 Grid Dimensions (NXxNY) : 109x91 12) Now MUCH easier to determine the proper grid navigation for AWIPS. When running eta_convert.csh the CORRECT navigation information is printed on the screen along with arguments for running maksuparg. 13) When sending data to AWIPS a *.cdl file is created with the correct grid dimensions. 14) The WS Eta version number is displayed when running eta_run.csh and eta_convert.csh. 15) 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 worketa31g directory and make link from worketa For example: % cd /usr1 % mkdir worketa31g % ln -s worketa31g worketa 2) Download the model distribution files and place them in the worketa31g directory a. worketa_soostrc_v31g.tar.gz b. worketa_sfc_LittleE.tar.gz (for Linux) c. worketa_topo.tar.gz and for binary users d. worketa31g_bin_linux_55x91_2CPU.tar.gz (or another binary) and if you desire: e. install_wseta.csh f. wsetadir.tar.gz g. worketa_v31g.README 3) Move all files into the worketa31g directory 4) Install Either: % tar -zxvf worketa_soostrc_v31g.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") +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Robert A.
