General description

• Automatic acquisition of the basic weather
  parameters measured by sensors (pression, air and
  sea surface temperature, humidity, wind)
• Input of human weather observations
• Data check, processing and storage
• Generation and transmission of normalized
  encoding messages (via satellite)
• Display of the parameters

Pressure,Temperature and Humidity PTB 220
HMP35DE BATOS II PTU200
(Vaisala)

• Pressure
• 800 to 1100 hPa
• Air temperature
• -30 to 50 C
• Relative humidity
• 0,8 to 100

8
Water temperature PT100 SPCK PROSENSOR

• Hull contact sensor (WMO recommandation)
• (platinium resistor temperature sensor)
• -80 to 160 C

9
Wind Speed and Direction

• Measures speed and direction (relatively to the
  ship)
• True direction calculated by the software (using
  speed, heading and the true rout of the vessel)

• BATOS II CV3F Ultrasonic Wind Sensor (LCJ
  Capteurs)
• New generation wind speed and wind direction
  measurement device
• Resolution 0.1 kn
• Useful range 0.5 to 99.5 kn
• Wind direction resolution 0.1 degree
• Temperature range 0 to 40C

• Young 05106
• Resolution 0.2 kn
• Useful range 0 to 120 kn
• Wind direction resolution 3 degrees

10
Screen Miniature marine SOCRIMA

• Naturally ventilated multi-plate screen providing
  a good protection of temperature and humidity
  sensor
• Enclosure 20 cm (D) x 50 cm (H)
• To be installed on the deck

11
Software

• Checks the measurement to ensure data quality
• Generates normalized weather messages (code 41)
  every 1, 3 or 6 hours
• Sends on automatically the messages via satellite
• Data storage (hourly, during 6 months)
• Sensor data display in real-time and help for
  human observation capture

12
Communication Thrane Thrane

• Inmarsat Mini C
• Thrane Thrane TT-3026M comprising transceiver,
  omni-directional antenna and GPS receiver in one
  single unit

13
Current Network at Météo France
14
Current network at Météo France

• 30 BATOS set up on VOS (Volontary Observing
  Ship) in 2004
• Increasing of the number of observations
• Robustness of the system
• Quality of the data
