9. VOSClim Suspect List Feedback
Advise RTMC of investigations & actions taken to correct bad data identified on the VOSClim Suspect List
Example:
G'day Colin (Sarah for info)
Re: SEAKAP (VNNM) cited for RH.
I inspected this vessel (SEAKAP) on 09/01/07, and I noted that the
clip supporting the reservoir in the screen had corroded and broken
off. It’s possible that the reservoir may have toppled over and readings
taken when the wick was dry. A new clip was fitted during the
inspection including a fresh wick on the wet thermometer. RH should
be OK now.

10. Quality Information Relay Mechanism
JCOMMOPS quality information relay
Originally implemented for drifting buoy
Mailing list
Web page
Met. Services in best position to undertake QC
Appropriate tools
Assimilation schemes
Models
Goal
Detection of systematic errors
Relay of information to data producers

11. Quality Information Relay
Under JCOMMOPS web site:
“Monitoring”
”Quality”
”Ship based”
Posting quality information messages
UK Met Office monitoring statistics
NOAA Surface Marine QC flags
GTSPP monthly QC report

12. Quality Information Relay
From data users
Know quality & problems
Detect systematic errors
Don’t know who operates ship
Back to data producers
Can take corrective action
Check/change instruments
Remove bias
Suppress from GTS

13. Quality Information Relay
Via JCOMMOPS
Identification of ships and contact points
Database loaded thanks to
Pub. 47 information
Other information e.g. E-SURFMAR
Direct contacts
Advantages
Rationalization
Automated =>operational service
One reporting portal
Speeds up correction of problems

15. Onboard QM TurboWin Tool
From TurboWin Ver3.6 there is the ability for the PMO to view the Obs on screen in traditional logbook coded format whilst on board the ship
IMMT data not easily readable, but new option allows PMO to view the Obs for monitoring purposes

QM Feedback to Ships
Vital that NMS provide feedback about Obs quality and quantity to National VOS
Real-time feedback via PMO visit, , or phone call is most effective as targets current observers
Feedback on problems should be done in a manner to encourage and assist observers
Most ships view feedback whether good or bad as positive as it demonstrates their Obs are being used
Always include some thanks and encouragement in feedback messages
