Additional improvements to programs have been made to improve use with large grids by removing grid limitations from several programs and librariy routines.
Additions to 5.10.4 include:
The Unidata release of GEMPAK has been modified to support building the package using the gfortran compiler now being provided on most Linux platforms. Other local modifications include the ability to display the UNIWISC data stream satellite compressed images without unpacking, relieving sites from the need to use the LDM-MCIDAS pnga2area decoder, thereby freeing real-time ingest resources, and conserving disk space.
Additions to 5.10.3 include:
The Unidata applications training workshop for GEMPAK was conducted July 23-25, 2007. GEMPAK 5.10.3 was used for the workshop which included 17 participants. An added activity for participants this year was a data scavenger hunt which put the skills and tools learned by the attandees to use in finding clues embedded within data in order to arrive at their destination.
NCEP developers have provided notification for retirement of five legacy GEMPAK GD programs. They are: GDCNTR, GDSTREAM, GDWIND, GDMAP and GDPLOT. The functionality of each of these programs is fully incorporated into GDPLOT2. In addition, GDPLOT2 provides additional capabilities beyond the capabilities provided by these individual programs. Minimal changes are needed to go from the legacy program parameter settings to GDPLOT2 parameter settings. The last release to support these programs will be 5.11.2 (February, 2008).
Additions to 5.10.2 include:
NCEP is continuing development of XML/XSLT infrastructure within GEMPAK as part of the creation of products by NMAP2. Future development will include a migration of the current table structure from column based formats to XML, which will remove legacy issues regarding metadata and precision, as well as increase the utility of these tables with other packages. An overarching goal in the GEMPAK development is to separate the library routines from the underlying data files and formats and migrate toward a Service Oriented Architecture (SOA). The current transition of grid routines from Fortran to C is part of this effort. This will facilitate the use of GEMPAK routines in the next generation AWIPS development (ca. 2011 timeline for National Centers). A primary benefit of this work will be the ability to support a wider range of data sets, including remote access.
Dr. Chuck Graves hosted a GEMPAK and IDV site visit to SLU March 19-21, 2007. The visit provided direct interaction with undergraduate and graduate classes, one-on-one time with individual students as well as site administrator, a departmental presentation on Unidata activities, and a presentation at the student AMS meeting.
Iowa State is actively using GEMPAK radar mosaics with their mesonet products in GIS applications. To facilitate this process, I developed the GEMPAK program NEX2IMG to generate composite images which can be used with a file to provide GIS navigation information. Daryl Herzmann has put together a How-To document to help other sites set up their own radar mapservers.
All the documentation for the GEMPAK workshop is made available through the GEMPAK tutorial. Included in the presentation are numerous sample exercises and output samples. This format of presentation allows workshop participants to be able to review or utilize any of the material at their home institution. The tutorial is updated as new features dictate.
