GTS data disseminationGTS data dissemination
• WMO Global Telecommunication System used to disseminate data in real time.
• Details on http://www.jcommops.org/DBCP/gts • Assistance from myself and CLS (Argos) to
share data easily.• Data checks:
– Metadata and timeliness www.jcommops.org or www.osmc.noaa.gov
– Data Quality control on http://www.meteo.shom.fr/qctools/ and via monthly statistics

Barometer BuoysBarometer Buoys
• JCOMM aims to have all buoys in high latitudes measuring Air Pressure
• Barometer Upgrades (SVPB) offered by drifting buoy manufacturers through financial support by the GDP (AOML)

JCOMM and the International JCOMM and the International contextcontext
• Two important meetings next year– Ocean Observations 09– JCOMM III
• New JCOMM website www.jcomm.info
• Enter contact details

WMO Sustained observing systemsWMO Sustained observing systems
• WMO fully supports the ongoing efforts and
research coming from the IPY
• Sustained Arctic Observing Network
– 3 workshops in total (3rd one in October)
– www.arcticobserving.com
• WMO Congress (Cg-XV, 2007) established a
Global Cryosphere Watch (GCW).
12
Iridium Pilot ProjectIridium Pilot Project
• Seeks to evaluate the feasibility of Iridium
technology for real-time telecommunication
of drifter data
– under various conditions e.g. in wide temperature
ranges, remote ocean areas and in rough seas,
where the buoy will be frequently submerged
• DBCP funds used to “upgrade” 50 Argos
buoys to Iridium ($500 each) to be deployed
worldwide, to allow inexpensive access to

• Number deployed so far: 73
• Number on GTS today: 44– Australia 2– India 2– USA 3– UK 3– France 4– ESURFMAR 30
• Need buoys in the Polar regions, Pacific ocean and central Atlantic

FindingsFindings
• Arctic buoys
• Transmission and data format
• Timeliness / delays
• Positioning

Iridium Buoys in the ArcticIridium Buoys in the Arctic
• Météo France and SAMS both deployed Iridium buoys in the Arctic, and found:1. Iridium drifters didn't report
when the temperature was below -35C. SBD modem 9601 doesn't work below this temperature.
2. due to the cold conditions, the batteries drained faster than at mid-latitudes
