  1. Review of Argo data performance on GTS Anh Tran ADMT10 Sept 30 – Oct 2, 2009

  2. Argo TESAC received on GTS from various data centers • AMMC – Australia • CWOW – Canada • EGRR – Exeter • RKSL – Seoul • KWBC – Washington & Landover • LFPW – Toulouse • RJTD - Japan

  10. TESAC received from Argo floats since 2001

  11. Number of Argo TESAC duplicates on the GTS from various bulletin headers

  12. TESAC versus BUFR since Sept 10, 2009

  13. Summary • There are still small number of Argo TESAC duplicates on the GTS. • There aren’t any Argo TESAC with depths greater 2500 db • There is no Argo TESAC with instrument code error. • Volume of BUFR message is still much lower than volume of TESAC • No Bufr messages on GTS from AMMC, EGRR, KWBC, LFPW, and RKSL

  14. Information • BUFR encoded Pressure • In section 1, you need to record your data center code. The information can be found in Common code table document available at: http://www.wmo.int/pages/prog/www/WMOCodes/OperationalCodes.html • Argo BUFR template can be found at: http://www.wmo.ch/pages/prog/www/WMOCodes/TemplateExamples.html • GTS information can be found at: http://www.wmo.int/pages/prog/www/ois/Operational_Information/index_en.html

  15. BUFR template for Temperature and salinity profile observed by sub-surface profiling floats • It is proposed to represent this template by a descriptor 3 15 003. • 3 15 003: • 001087 - WMO Marine observing platform extended identifier • 001085 - Observing platform manufacturers model • 001086 - Observing platform manufacturers serial number • 002036 - Buoy type • 002148 – Data collection and/or location system • 002149 - Type of data buoy • 022055 - Float cycle number • 022056 - Direction of profile • 022067 - Instrument type for water temperature profile measurement • 301011 - Date • 301012 - Time • 301021 - Latitude and longitude (high accuracy) • 008080 - Qualifier for quality class • 033050 - Global GTSPP quality class • 109000 - Delayed replication of 9 descriptors • 031002 – Extended delayed descriptor replication factor • 007065 – Water pressure • 008080 - Qualifier for quality class • 033050 - Global GTSPP quality class • 022045 - Subsurface sea temperature • 008080 - Qualifier for quality class • 033050 - GTSPP quality class • 022064 - Salinity • 008080 - Qualifier for quality class • 033050 - GTSPP quality class
