  3. Case for change briefed to NWS Corporate Board – Nov 2004 AWIPS Present State Summary Hardware AWIPS hardware was in good shape Communications Infrastructure AWIPS communications infrastructure was in OK shape Data AWIPS Data was in need of improvements Software AWIPS software was in critical need of improvements Costly software development, maintenance and inability to meet NWS and customer needs Corporate board direction to focus on addressing software shortcomings Plan and requirements developed Shaped portions of the AWIPS O&M re-compete activity Why Change?

  4. What is AWIPS Evolution? • AWIPS Evolution • A long-term project which delivers a modern, robust software infrastructure that provides the foundation for future system level enhancements • AWIPS II • Implements a modern Services Oriented Architecture (SOA) infrastructure • First output of AWIPS Evolution and provides the foundation for all subsequent improvements • AWIPS II Extended - Creation of a seamless weather enterprise spanning NWS operations • Migration of NAWIPS into the AWIPS II SOA • Delivery of thin client • Support to the Weather Service Offices and Center Weather Support Units • Integration of “orphan” systems (e.g., Weather Even Simulator) • AWIPS II Enterprise Enhancements • Data Delivery Enhancements • “Smart push-smart pull” data access • Katrina satellite WAN back up • Integrated visual collaboration • Visualization Enhancements • Information Generation Enhancements

  5. AWIPS EvolutionObjectives • Establish Service Oriented Architecture for AWIPS and NAWIPS • Create a seamless weather enterprise that supports all levels of NWS operations from National Centers to WSOs • Build a common development environment that will be used by all developers • Establish infrastructure for GIS integration • Enable access to data independent of its location, i.e., provide access to data not resident locally at the WFO or RFC. • Provide infrastructure for real time graphical collaboration between • WFOs, RFCs and centers for enhanced internal collaboration • Other NOAA entities and • Trusted partners, e.g., Emergency Managers • Implement a Common AWIPS visualization environment (CAVE) used by all applications • Standardize generation of NWS products and services

  6. AWIPS IIRe-Architecture Approach • Perform “black-box” conversion • Preserve existing functionality, look and feel on top of new infrastructure • Thorough field validation and acceptance before deployment • No loss of functionality • Deployed system current with deployed AWIPS capability (i.e., OB9) • Use open source projects - No proprietary code • JAVA and open source projects enable AWIPS II to be platform and OS independent • No plans to move from Linux • ADE enables collaborative development • OS, Platform independence allows non-Linux based research to be easily integrated into AWIPS II

  7. AWIPS II Features • AWIPS Development Environment (ADE) • Used by all AWIPS developers (National, Regional, & Local) • Developers concentrate on new capabilities, not re-implementing existing ones (i.e. screen I/O, communications protocols, data access routines, logging routines, or other previously developed capabilities) • Software can be developed on a variety of platforms • Robust infrastructure for improved software O&M • Use of plug-ins: visualization extensions; new data types and transforms • System level, remediation, core services reduce system complexity • Improved support for local requirements (e.g., local apps, scripts, plug-ins) • Common AWIPS Visualization Environment (CAVE) • Provides a common development and execution environment for AWIPS GUIs (e.g. D2D, NMAP, GFE, etc.) • Ability to pan/zoom large data sets (Raster & Vector) with flexibility over data rendering • GIS tools • Thin Client (Web Browser) enabled • Dynamic Load balancing • Processing dynamically allocated among available CPUs

  10. AWIPS EvolutionGovernance Model • What is it? • Governance model controls the development, test, integration, configuration management, deployment and support of the new system -- both hardware and software • Why? • AWIPS II offers new levels of flexibility and extensibility • New rules needed to take advantage of system capabilities and also define limits • Tension between unlimited modifications and ability to support the system • Sample issues for consideration • Monolithic configurations no longer required -- how do we manage site specific configurations? • Plug ins can be down loaded and installed on demand • Scripting that modifies AWIPS menus, functions • Flexible Governance Model needed for limited open source implementation

  11. AWIPS IIWhat does it mean to ensembles? • NAWIPS migration • Same infrastructure supporting both NAWIPS and AWIPS applications • Algorithms • Common library for meteorological and hydrological calculations and tools • Data delivery • Smart push-smart pull may provide more flexibility for access to large data sets • Visualization • Supports new tools and techniques for visualizing ensemble data • Information Generation • New architecture for product generation and delivery will allow tailored products capturing uncertainty

  12. AWIPS IITraining • Strategic Training Plan developed • Training targeted for the following groups: • ESAs • ITOs • AWIPS and application focal points • Developers (both baseline and local) • NCF • SST • Training Organizations involved in planning, developing and implementing courses

  13. AWIPS IITesting • Layered testing strategy • Different testing phases overlap – functionality tested multiple times in different settings • ADE usage • Not formal testing, but expect to get feedback as developers use the ADE • Algorithm V&V – • Assist algorithm choice • Verify port of algorithms • V&V • Task order validation • Executed by dev orgs in controlled setting • Performance testing – Evaluate system against known and developing benchmarks • Acceptance testing – part of the task order acceptance process • Risk reduction • Side by side testing of new system by field personnel in a “lab” environment • Testing at limited number sites in manner that doesn’t impact operations • Operational Test & Evaluation (OT&E) • Formal testing of the entire system • Tests system interfaces, operations, support, training, etc.

  14. AWIPS IIRisks and Challenges • Organizational challenges • Significant off contract workload on Government • Matrixed structure increases project complexity • Performance • Supporting the short fuse warning mission • Handling large global data sets • Schedule • Completing the migration and testing • Migration of local applications • Local applications outside the baseline • Not a Raytheon responsibility

  15. Summary • New architecture defined and infrastructure delivered • ADE 1.0 delivered June 14, 2007 • Application migration underway • Migration Plan delivered June 2007 • AWIPS baseline migration to be completed FY09 • Local applications migration planning in progress • Incremental approach will extend AWIPS II architecture throughout NWS • AWIPS II and subsequent enhancements will provide more flexible foundation for delivering products that capture uncertainty
