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:
Argo BUFR template can be found at:
GTS information can be found at:

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:
WMO Marine observing platform extended identifier
Observing platform manufacturers model
Observing platform manufacturers serial number
Buoy type
– Data collection and/or location system
Type of data buoy
Float cycle number
Direction of profile
Instrument type for water temperature profile measurement
Date
Time
Latitude and longitude (high accuracy)
Qualifier for quality class
Global GTSPP quality class
Delayed replication of 9 descriptors
– Extended delayed descriptor replication factor
– Water pressure
Subsurface sea temperature
GTSPP quality class
Salinity
