  1. Presentation & Evolution of the Shipboard Automatic Weather StationBATOS TECO 2005 - BUCAREST

  2. General description of the systems • Technical information about the components • Current network at Météo France • Future work

  3. General description Screen Satellite communication Weather sensors

  4. 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

  5. General description and evolution

  6. Technical Information

  7. 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 temperaturePT100 – 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 40°C • Young 05106 • Resolution: 0.2 kn • Useful range: 0 to 120 kn • Wind direction resolution : 3 degrees

  10. ScreenMiniature 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. CommunicationThrane & 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

  15. Current network at Météo France

  16. Current network at Météo France

  17. Future work • Thermosalinometer for TRACKOB messages • Data compression • Transmission frequency adaptation
