21692 Obs recvd from NZ VOS SHIPS in 2005
NZ VOS Instrumentation/Automation
• Precision Aneroid Barometer• Marine Barograph• Stevenson Screen + thermometers• Sea Bucket• TurboWin electronic logbook software– One Marine AWS- based on Sutron
9000RTU– Two Marine AWS planned for 2006
CommunicationsCommunications
• Most ships send via SAT C - special access code 41
• Few coastal ships phone/fax to 0800 number
Inspection Regime
• All NZ VOS inspected at least once per year
• Some ships receive several visits
• All barometers calibrated against PMO’s Vaisala PTB220AD Transfer Standard barometer which is traceable to National/International standards
• Foreign VOS ships visited when possible and on request
Challenges & Difficulties• Volatility - constant change in ships, routes,
personnel affects VOS programme• Security issues from exposure of Ship details
on web and the potential impact on VOS fleet• Compliance with ISPS & Customs Regs• Shorter port stays - more after hours &
weekend visiting• Language problems
Receipt of OBs Monitored
No OBs can be first sign of problems
• Monthly count of number of Obs per NZ VOS ship
• Follow up ships identified as sending few or no Obs
• Use ‘Time of Receipt’ Monitoring tool developed by UKMO
OBs Quality Monitored
• PMO access to Real Time GTS OBs
• Forecaster & Data Entry feedback
• Daily summary of OBs with coding errors
• Use of Meteo France VOS QC Monitoring site
• UKMO monthly Monitoring Stats
Important Factors for successful Important Factors for successful VOSVOS
• RealTime access to GTS SHIP OBs
• Use of monitoring tools to identify ships with problems
• Timely follow up to rectify problems
• Providing ships with clear instructions
• It’s about being pro-active
What could improve my job?
• Up to date on-line WMO No 47
• Reliable callsign/ship name/Sat C matching
• Greater global communication between PMOs
Steering Strategies
• Number of ships in VOS not important - it’s the number that report that count
• Coded OBs must be received in real-time to be of maximum benefit to the Forecasting Office
• Doesn’t matter which country a ship reports for, so long as it reports.
PMO JobPMO Job
• Its unique• Meet many interesting people• Visit a huge variety of ships• Job is challenging• Doing it well makes a difference
PMOs efforts directly impact on the quality & quantity of OBs from Ships
