NWS/Universities will be hot for this. Chiz ---------- Forwarded message ---------- Date: Tue, 25 May 1999 10:02:30 -0400 From: Geoff DiMego <address@hidden> Subject: Workstation version of Eta Folks: On behalf of Louis Uccellini, Director of NCEP, and Steve Lord, Acting Director of EMC, I am pleased to announce availability of a workstation version of the Eta Model. Included are codes to facilitate a local application at high resolution, terrain and other fixed field data sets, codes to extract initial and lateral boundary conditions from grids downloaded from the NCEP or OSO servers and a post-processor code which allows generation of a myriad of gridded output in GRIB. Matt Pyle has performed the herculean task and, together with those listed in the acknowledgments, deserves our praise and gratitude. PLEASE NOTE our requisite disclaimer: "It should be clear to the user that the codes and manual are made available in their present form and status and that NCEP makes no commitment to provide the user with any kind of further support in their local configuration, testing, maintenance or upgrading. The codes can be used for research or experimental forecasting, but cannot be provided to any other individual or organization without prior authorization by the NCEP. Furthermore, publications which include results obtained using the NCEP Eta workstation codes should acknowledge receipt of the codes from NCEP." and the NWS disclaimer on Use of Data and Products reproduced at the end of the e-mail. Without further ado, her is what Matt Pyle wrote: --------------------------------------------------- An initial workstation version of the Eta is now available (really!) It has been tested on SGI, HP and IBM workstations (and compilers). While this doesn't cover all existing platforms, we feel an early release has more value than the perfectly complete one that comes a decade from now. This self-contained modeling package can be downloaded via anonymous FTP from ftp.ncep.noaa.gov. Once logged in, cd to /pub/gcp/wrkstn_eta and download the wrkst_package.tar.Z file. One major word of caution upfront:this rendition of the package REQUIRES a FORTRAN 90 compiler. A FORTRAN 77 product may be developed in the coming months, but for now FORTRAN 90 is required! Topography files are also located in this directory and must be downloaded separately. The topography data are stored in latitudinal strips covering 10 degrees of latitude from 180W to 40W. The file name indicates the southern latitude of the strip. Files residing in this directory cover between 10N and 80N. Download the strips that will cover your expected domain(s). Also download a copy of the user's manual, available in beautiful postscript and .pdf (Adobe Acrobat Reader, freeware downloadable at http://www.adobe.com/prodindex/acrobat/readstep.html) documents, and an ASCII file as well. These files all have the same information and are named manual.ps, manual.pdf, and manual.ascii. The manual describes in some detail how to install and use the package. Much effort was spent in writing and verifying the accuracy of these instructions; please let it be your first source of information regarding the workstation version of the model. Uncompress the wrkst_package.tar.Z file, and follow the instructions for installation and use of the package. If you download the package, please send us an e-mail so we can keep a list of workstation Eta users. There is no sinister motive at work here; despite the disclaimer above, it will just allow us to more easily notify you of user meetings, code updates, improvements, problems, etc that might be made available in the future. ------------------------------------------------------- Acknowledgments: A reference list included in the manual provides a more thorough list of individuals responsible for the Eta model's primary development (dating to the original work on the Eta by Mesinger and Janjic). The following is intended to acknowledge those who have most directly aided this current workstation release. The direct predecessor of this release was received courtesy of John Snook, then of FSL, in the fall of 1998. His package had integrated codes originally developed by the European (Yugoslavian/Greek) Eta community and by the Environmental Modeling Center at NCEP. I've tried to improve them and make them into a user-friendly package. Recent work has incorporated the latest NCEP operational codes. Guidance on converting the Cray C-90 code into a portable workstation code was provided by Michael Baldwin. The work- station version of the post-processor was made possible by the GRIB utilities developed by Mark Iredell of NCEP. ------------------------------------------------------- NWS disclaimer on the Use of Data and Products The information on government servers are in the public domain, unless specifically annotated otherwise, and may be used freely by the public.
