4. MFS-VOS system
Activities in the framework of EuroGOOS and MedGOOS
Supports the Mediterranean Forecasting System /Adricosm
Included in the GMES Ocean component

5. Requirements An ideal sampling design is based on four goals:
- 1. provide repetitive measurements along transects from coast to coast,
 2. the transects must cross significant dynamical features of the circulation,
3. the sampling distance should resolve, as well as possible, the mesoscale,
4.  the technologies for data collection must be robust and simple, to be used on ships of opportunity, eventually by ship personnel.

20. Transmission tools: from ARGOS to Globalstar
Initially only some significant points extracted from the temperature profiles were transmitted by mean of ARGOS in real time.
In order to have the full resolution profiles, the data transmission system was changed with the use of GSM and Internet systems. The data were transmitted in near-real time, e.g. with a delay of about 12 – 20 hours from data collection.
Now full resolution profiles are transmitted by means of the Globalstar system

21. Advantages: from ARGOS to Globalstar

22. Data Flow and QC
Data are transmitted from ships to MFS-VOS Thematic Data Centre
Data are QC with a unique (improved) NRT procedure

24. Sources of Error: wind/ship contact

25. Sources of Error: ground connection

26. QC Methodology – Initial Version
The NRT.QC.XBT procedure then proceeds with 8 steps that in synthesis are (Manzella, Scoccimarro, Pinardi, Tonani )
initial visual check
gross range check*
position control*
elimination of spikes*
interpolation at 1 metre interval*
gaussian smoothing*
general malfunction control*
comparison with climatology*
final visual check, confirming the validity of profiles and providing an overall consistency

27. Comparison with climatology
This is done in terms of ‘distance’ of the XBT data to the mean monthly profile. If this ‘distance’ is less than 2 standard deviations, the XBT data are considered of good quality, if it is between 2 – 4 standard deviation or is greater than 4 a flag standard deviations the data values are flagged.

40. QC Methodology Improvement
The use the ACQUISITION TIME (fixed increments due to the 10 Hz sampling rate) as free parameter.
The APPLICATION of Gaussian smoothing before interpolation at 1 metre interval.
START-UP problem  Systematic difference at the seasonal thermocline depth. The XBT recording system needs time before it measures stable T values (within 0.1 ºC). The observed averaged delay is 0.3 ± 0.1 s (2.0 m). Each profile could be rescaled.
NEW FALL RATE COEFFICIENTS seem to be required in Mediterranean for XBTs.
