Project Status: In Development Anticipated Release Date: Spring 2013
AWIPS II is a the next generation weather forecasting, display and analysis package currently being developed by the National Weather Service. AWIPS II is a Java application designed to eventually run on multiple platforms, and it incorporates many open source technologies such as Apache Qpid, PostgreSQL and PyPIES.
| Operating System | 32-bit Red Hat or CentOS Linux (installed on 64-bit architecture) |
| Memory | 8 Gb (minimum) 16 Gb (recommended) |
| Graphics | 256 Mb video memory minimum OpenGL 2+ |
| Storage | 100 Gb recommended |
Q: How is GEMPAK related to AWIPS II?
A: GEMPAK functionality, specifically the underlying analysis and diagnostic routines, will be included with AWIPS II, most likely as wrapped code. AWIPS II is being developed for a "black box" GEMPAK transition, meaning batch scripts and automated processes which call GEMPAK routines would not require updating after migrating to AWIPS II.
Q: What about 64-bit support?
A: 64-bit systems are currently unsupported, but on machines which meet the recommended system requirements, with the correct 32-bit libraries available (most importantly OpenGL), CAVE will run. 64-bit EDEX servers and CAVE clients are undergoing development at Raytheon with plans for release after national deployment of 32-bit AWIPS II.
Q: Can I get an early copy of AWIPS II for evaluation?
A: The UPC is unable to provide evaluation copies of AWIPS II at this time, but is making plans for early beta testing at university sites.

AWIPS II Testing at the Boulder, Colorado WFO
On March 6, 2012 several members of the Unidata Program Center staff traveled to the National Weather Service's Weather Forecast Office (WFO) in Boulder, Colorado for an update on AWIPS II system testing. Nezette Rydell, Meteorologist in Charge at the Denver/Boulder WFO, provided background information on the AWIPS II operational testing process and current status. Meteorologist David Barjenbruch provided a demonstration of how AWIPS II will be used in the WFO. The visit was a part of the UPC's ongoing involvement with the AWIPS II project and efforts to make the system available to the university community once it is operational.

Q: What is AWIPS II?
A: The National Weather Service is in the process of developing the next generation of its AWIPS software (AWIPS II) to provide a comprehensive package in support of its forecasting and public service operations. This new software will be developed in Java, allowing it to run on more platforms than the current AWIPS software. Many of the underlying technologies in AWIPS II will be based on open source projects and the plan is to make AWIPS II software also open source. Currently, the NWS National Centers and NWS field forecast offices use different tools to support their mission, with the National Centers using NAWIPS, and NWS forecast offices use AWIPS, which is fundamentally different and not compatible with NAWIPS. The new AWIPS II architecture will allow the NWS to reduce development time, expand data access and provide better integration and collaboration between the NWS field offices, river forecast centers and National Centers.
Q: Who is developing AWIPS II?
A: Raytheon is responsible for developing the underlying infrastructure for AWIPS II and migrating the existing AWIPS functionality into that infrastructure. NCEP is responsible for migrating the existing GEMPAK/NAWIPS functionality into the AWIPS II framework.
Q: How is GEMPAK related to AWIPS II?
A: GEMPAK functionality, specifically the underlying analysis and diagnostic routines, will be included with AWIPS II, most likely as wrapped code. AWIPS II is being developed for a "black box" GEMPAK transition, meaning batch scripts and automated processes which call GEMPAK routines would not require updating after migrating to AWIPS II.
Q: What is Unidata's role in all this?
A: The Unidata Program Center distributes and provides support for GEMPAK to our member sites. Membership in Unidata is open to U.S. colleges and universities, and is free of charge. GEMPAK is also available as unsupported software without charge to organizations which do not participate in Unidata through the limitations specified in the Unidata participation policy. The UPC release of GEMPAK/NAWIPS incorporates several additions developed both locally and at other locations to enhance the use of real-time data aquired through the Unidata IDD, and through instructional case studies such as those developed at COMET. It includes GARP (GEMPAK Analysis and Rendering Program) which was developed by COMET.
Q: Why is NCEP moving away from GEMPAK?
A: The National Weather Service announced plans in 2007 to cease development of NAWIPS in August 2008 and proceed with a migration of the functionality of that package to the new AWIPS II environment. The decision to migrate NAWIPS to AWIPS II was made unilaterally by NWS. Since NCEP's primary goal is to support the National Centers, Unidata had no input on this decision.
Q: What is NCEP's plan for NAWIPS/GEMPAK?
A: NCEP intends to migrate all NAWIPS/GEMPAK functionality to AWIPS II and intends to make AWIPS II available to the Unidata community.
Q: How long will the UPC support GEMPAK?
A: Unidata plans to support the last version of the current GEMPAK/NAWIPS software for 18 months after the first official release of AWIPS II by NCEP to the National Centers and to the Unidata community.
Q: Why doesn't the UPC support GEMPAK forever?
A: Historically, the UPC has relied heavily on and leveraged the efforts of several (5+) software developers at NCEP to advance GEMPAK while making local enhancements to address the needs of Unidata users. NCEP developers addressed data stream changes, added new features to the NAWIPS GUI programs, GEMPAK programs and libraries, and provided bug fixes. The UPC has always dedicated (and continues to dedicate) one staff member for the development of additional functionality required by the community and to support porting to more platforms than NCEP. NCEP will no longer be developing GEMPAK/NAWIPS and Unidata does not have the same resources that NCEP had to continue development on its own to address new data types or datastream and operating system changes.
Q: When the UPC stops supporting GEMPAK, can I still use it?
A: The GEMPAK source code is freely available and will still be accessible in some form after the UPC ends official support. It will not stop working on any certain date. Furthermore, the existing support materials (tutorial, help manual and documentation) will still be available on line. The gembud mailing list will be kept active so GEMPAK users can provide community support to each other.
Q: What about 64-bit support?
A: 64-bit systems are currently unsupported, but on machines which meet the recommended system requ irements, with the correct 32-bit libraries available (most importantly OpenGL), CAVE will run. 64-bit EDEX servers and CAVE clients are undergoing development at Raytheon with plans for release after national deployment of 32-bit AWIPS II.
Q: What about AWIPS II source code?
A: Unidata is currently in the process of obtaining AWIPS II source code through project partners at NOAA. As AWIPS II is still in development, the UPC is unable to say when source code will be available and what conditions, if any, will be in place.
Q: Can I get an early copy of AWIPS II for evaluation?
A: Unidata has been provided access to ongoing AWIPS II releases and updates hosted by the NCEP System Integration Branch, in order to evaluate, test and document the hardware and software requirements for the GEMPAK/NAWIPS community. NCEP will begin system and field OTE (operation testing & evaluation) for the National Centers, with the first national deployment of AWIPS II currently scheduled for Spring 2013. Unidata plans to provide AWIPS II to a subset of the GEMPAK community for testing and evaluation before this scheduled release date, though the exact time when this will happen is still unknown. Unidata is currently held under an non-disclosure agreement with respect to AWIPS II, which restricts us from "sharing" development copies and source code. We are hopeful that before the approximate scheduled national deployment date of Spring 2013 we will be allowed to distribute evaluation copies to the community for site testing. The ultimate goal will be Unidata's release of AWIPS II coinciding with the NCEP release to the National Centers. This means that the Unidata community will have available to it the full software package, installation and configuration documentation, and the help of Unidata support staff to assist with the migration.
