9 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools9 VOSClim Suspect List Feedback Advise RTMC of investigations & actions taken to correct bad data identified on the VOSClim Suspect 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. Cheers Taffy (PMA Sydney)

10 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools10 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 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools11 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 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools12 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 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools13 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 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools15 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

18 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools18 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

19 16-21 April 2007SOT-IV, VOS Quality Monitoring Tools19 Use of the Monitoring Tools and timely feedback to ships to correct problems will improve the quality and quantity of Obs provided by VOS
