Transition Goals

• Community understanding of Transition Plan.
• Activities transparent to both research and
• operational users, both domestic and
  international.
• Track metrics developed from operational and
• research requirements.
• Establish and maintain successful NWS / OAR
• partnership enabling transfers from research
  to
• operations.

Phased Transition

• NDBC assumed management responsibility on
  October 1, 2004.
• Technical interface team will be at PMEL and
  NDBC as appropriate during the transition
  process.
• The tropical mooring data assembly center (DAC)
  will be established at NDBC.
• PMEL will be funded to conduct FY2005
  operations.
• Configuration change process allows for new
  requirements subject to NOAA approval process.
• Acquire new resources (FY06 CCRI Tropical Buoy
  Expansion FY07 Program Plan) to capitalize on
  tech development of the next generation of moored
  buoys.

Software TransitionApproach

• TAO consist of five subsystems, as identified
  below
• Real-time Processing Subsystem
• Inventory Calibration Subsystem ()
• Real-time Data Monitoring Subsystem
• Delayed-Mode RAM Processing Subsystem
• Web Data Display and Delivery Subsystem
• The TAO transition is primarily a re-hosting
  effort from Solaris at PMEL to Linux at NDBC.
  Otherwise, all software and data storage
  processes will remain the same.
• Due to the phased transition, there will be
  shared responsibility for the Inventory and
  Calibration Subsystem through FY06 when NDBC
  transitions the Engineering / Operational portion
  of TAO

Software TransitionSchedule

• Completed items
• Kickoff meeting between NDBC/PMEL October 2004
• Initial Requirements Meeting January 2005
• Receiving TAO ARGOS data at NDBC January 2005
• Software Requirements Specification February 2005
• Architecture Document February 2005
• Installation of two servers at NDBC March 2005
• End to End Testing Apr-Jun 2005
• Initial Operational Capability June 2005
• Full Operational Capability July 2005

Software TransitionStatus

• Real-time Processing Subsystem
• 29 programs and 42 scripts/Perl modules have been
  compiled and are being tested. MySQL database
  with 55 tables has been transitioned.
• Real-time Data Monitoring Subsystem
• 82 scripts (Shell, Perl, CGI) have been modified
  and ready to test.
• Web Data Display and Delivery Subsystem
• 1,523 programs have been compiled 239 scripts
  (CGI, Java) have been modified approximately
  3,000 modules are outstanding.
• Delayed Mode Subsystem
• All 560 software modules are outstanding.

10
Software TransitionIssues / Risks

• Much legacy software.
• Porting code versus a development effort requires
  more coordination upfront but less time for
  parallel testing.
• Requires PMEL support throughout migration.
• QA process is highly interactive.
• Present NDBC contract expires at critical time in
  schedule.

Transition Metrics
12

Summary

• Transition is proceeding.
• Re-hosting legacy software code is ongoing.
• Lack of OAR transition funding for PMEL is
  slowing transition.
• Tsunami efforts utilize some of the same folks.
• Availability of FY2006/2007 funding is needed for
  technology refresh.
• Timing of PIRATA transition undecided.

TAO Tropical Atmosphere Ocean

• Backup Slides
• Activities by Fiscal Year

14
FY04 ActivitiesPhase 0

• 1. TAO data used to detect and forecast 2004 El
  Nino
• 2. Transition Plan given to Climate Program
  Manager.
• 3. Internal and external groups reviewed plan.
• 4. Tropical portion of CCRI defined during
  PPBES06.
• 5. Climate Program addressed pre-planned
  product
• improvement in PPBES07.
• 6. PMEL / NDBC partnership learned valuable
  lessons
• in DART transfer.
• 7. NDBC / PMEL have provided Office of Global
• Programs with data management support.

15
FY05 ActivitiesPhase I

• 1. Maintain the existing TAO data availability.
  
• 2. Establish a tropical mooring data assembly
  center
• (tropical DAC) at NDBC.
• 3. Establish NDBC / PMEL TAO Transition Team in
• Seattle.
• 4. Provide Technology Refreshment Plan to
  Climate
• Program for approval.
• 5. Ensure TAO assets (i.e., buoys and ship
  resources)
• are available for use in research
  activities.
• 6. Provide next generation mooring proposal to
• Climate Program for approval.

16
FY06 ActivitiesPhase II

• 1. Maintain the TAO data availability.
• 2. Maintain DAC to support both researchers
• and operational users.
• 3. Continue to refresh obsolete TAO array
  components in accordance with the approved
  Technology Refreshment Plan.
• Fund technology development of next
• generation tropical mooring design.
• 5. Prepare PIRATA transition plan.

17
FY07 ActivitiesPhase III

• 1.  Maintain TAO array at present availability.
• 2.  Merge DAC with NDBC IOOS DAC.
• 3.  Complete procurement of tech refresh
• components.
• Fund Pre-Planned Product Improvements
• based on the next generation tropical
  mooring developments in response to operational
  gap.
• 5. Conduct final review of transition.
