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

• Buoy and Transmission costs

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
