9. 11-13 April 20112 nd IBTrACS Workshop9  First ever international meeting to specifically discuss best track data?  5-7 May 2009 - Participants worldwide  Topics ◦ Operational Best tracking procedures ◦ Wind-pressure relationships ◦ Wind speed conversions ◦ Global Reanalysis ◦ IBTrACS improvements  Meeting summary in AMS BAMS

10. 11-13 April 20112 nd IBTrACS Workshop10  Recommendations ◦ To IBTrACS team ◦ To forecast agencies (that make best track data) ◦ To the WMO  Collaboration ◦ Growing collaboration on BT issues amongst participants

11. 11-13 April 20112 nd IBTrACS Workshop11

12. 11-13 April 20112 nd IBTrACS Workshop12  The IBTrACS team should… ◦ Document BT procedures,  Work with agencies  Through a survey ◦ Provide all parameters as provided by original agency in IBTrACS ◦ Distribute official and unofficial datasets of other TC related data ◦ Archive all ancillary data ◦ Get involved with the IWTC

13. 11-13 April 20112 nd IBTrACS Workshop13  Best tracking agencies should … ◦ Report more parameters and use WMO format ◦ Document current and historic BT practices ◦ Standardize definitions of winds and wind conversions ◦ Rescue and archive documents relevant to BT data ◦ “Best track” throughout life cycle (through ET) ◦ Encourage best track data discussions at IWTC Held IBTrACS special focus session in La Reunion Accomplished by TCM through recognition of Harper report Many have worked with IBTrACS on the community survey

14. 11-13 April 20112 nd IBTrACS Workshop14  Endorse and/or formally adopt as global archive to aid RSMCs and TCWCs  Recommend improvements and enhancements  Collaborate with IBTrACS on improvements  Standardize and document best tracking procedures  Cooperate on survey of operational procedures

15. 11-13 April 20112 nd IBTrACS Workshop15

16. 11-13 April 20112 nd IBTrACS Workshop16  To continue the momentum of international collaboration by bringing together representatives from IBTrACS data providers, IBTrACS users and other TC researchers.  In addition, the workshop aims to address unresolved issues regarding construction, archive and use of best track data.

17. 11-13 April 20112 nd IBTrACS Workshop17  Need ◦ Much relies on quality of best track data  Approach ◦ Make producers aware of impact of poor BT data on weather and climate ◦ Make users aware of known BT issues and/or limitations

18. 11-13 April 20112 nd IBTrACS Workshop18  Need ◦ No assessment of BT data is available ◦ No better authors than the data producers ◦ No better time than the present  Approach ◦ Co-authors from Workshop participants/agencies ◦ Identify and catalog current and historic practices where appropriate ◦ Assess dataset quality and use

19. 11-13 April 20112 nd IBTrACS Workshop19

20. 11-13 April 20112 nd IBTrACS Workshop20  Need ◦ Formalize the structure of IBTrACS ◦ International direction and feedback on plans  Approach ◦ Enact the BT committee
