AWIPS II briefing

  1. 1. National Weather Service The Evolution of AWIPS NURO 5 September 2007 Jason Tuell Office of Science and Technology 1
  2. 2. Overview • The Why and What of AWIPS Evolution • Objectives • Re-architecture Approach • Roadmap • What does AWIPS II mean to ensembles? • Summary 2
  3. 3. Why Change? • 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 3
  4. 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 4
  5. 5. AWIPS Evolution Objectives • 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 5
  6. 6. AWIPS II Re-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 6
  7. 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 7

  10. 10. AWIPS Evolution Governance 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 10
  11. 11. AWIPS II What 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 11
  12. 12. AWIPS II Training • 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 12
  13. 13. AWIPS II Testing • 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. 13
  14. 14. AWIPS II Risks 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 14
