Outline
• Composition of the SOT.• Overview of the observing programs.• Objectives of the SOT.• Working arrangements. • Management Team.• Relationship with JCOMM.• Goals of SOT-IV.
16-21 April 2007 SOT Introduction and Session Goals, SOT-IV, Geneva 3
Composition of the SOT
• The JCOMM Ship Observations Team (SOT) consists of three successful and long-standing global observing programs:» The Voluntary Observing Ship (VOS) Scheme;» The Ship-of-Opportunity Programme (SOOP); and» The Automated Shipboard Aerological Programme (ASAP).
16-21 April 2007 SOT Introduction and Session Goals, SOT-IV, Geneva 4
Voluntary Observing Ship Scheme
• VOS:» Surface weather reports from all oceans and coastal areas;» Real-time GTS data (SHIP) and delayed-mode data; » ~ 5,000 ships (December 2006); and» ~ 200 ships equipped with AWS (December 2006).
• VOSClim – the VOS Climate Project:» High quality reference subset of the VOS used for climate
research, modelling applications and benchmarking;» Global target = 200 ships; and» ~ 200 ships (April 2007).

Ship-of-Opportunity Programme
• XBT SOOP:» Upper-ocean thermal profiles on repeat sampling lines;» Real-time GTS data (BATHY) and delayed-mode data;» Globally ~ 60 ships and ~ 24,000 profiles annually; and» Sampling mostly from merchant and research ships.
• Multi-disciplinary underway sampling:» Atmospheric and ocean carbon, fluorescence, pigments,
salinity and temperature;» Sampling mostly on research ships in conjunction with HDX
(High Density XBT);» Real-time GTS data (TESAC, TRACKOB); and» Other parameters mostly used and archived by the operator.

Automated Shipboard Aerological Programme
• Atmospheric profiles (temperature, humidity & wind) from radiosondes.
• Real-time GTS data (TEMP SHIP).
• EUMETNET (E-ASAP):» North Atlantic Ocean and Mediterranean Sea; and» Target of 16 ships and 4,640 TEMP messages in 2007
increasing to 4,860 TEMP messages in 2008.
• Elsewhere:» Ad-hoc, e.g. Japan, South Africa and some Navy vessels.

Objectives of the SOT
• To manage, coordinate and wherever possible integrate the VOS Scheme, SOOP and ASAP to support a range of well defined operational and research applications.
• To liaise and coordinate with other groups involved in using volunteer ships as environmental observing platforms with a view to their participation in the SOT.
• To improve national coordination between institutions involved in similar or related programs.
16-21 April 2007 SOT Introduction and Session Goals, SOT-IV, Geneva 12
Working Arrangements
• Sessions of the SOT occur biannually and incorporate plenary sessions of:» The VOS Panel (VOSP, including VOSClim since SOT-III); » The SOOP Implementation Panel (SOOPIP); and » The ASAP Panel (ASAPP).
• Scientific guidance is provided by expert panels and bodies for climate and operational meteorology.
• Most work is undertaken by intersessional Task Teams.
