Operational oceanographic data exchange and NEAR-GOOS Regional Real Time Data Base Takashi Yoshida Japan Meteorological Agency September 3, 2007NEARGOOS-NOWPAP Training Course on Remote Sensing Data Analysis
Why do you promote operational oceanographic data exchange? • To meet the increasing requirement of high quality oceanographic and marine meteorological information • Gland truth information for satellite observations • To ensure adequate supply of such data • Ocean is too big for one single country or organization to cover. • Because the marginal seas are surrounded by several nations, international cooperation is inevitable to cover the seas.
Global frameworks of operational oceanographic data exchange • JCOMM data exchange using GTS (DBCP, SOOP, VOS programme) • Argo (profiling float)
JCOMM data exchange using GTS • Based on the Global Telecommunication System (GTS) • Well regulated data exchange system • Standard data transmission protocol, format, etc.
GTS (Global Telecommunication System) • 3 WMCs (World Meteorological Centres) • 15 RTMs (Regional Telecommunication Hubs) Moscow Offenbach Prague Beijing Bracknell Sofia Washington Toulouse Tokyo Algiers Jeddah Dacar Cairo New Delhi Nairobi Brasilia Melbourne Buenos Aires
Observation platforms JCOMM data exchange using GTS Meteorological telecommunication centers GTS real time data dissemination with WMO CBS/JCOMM standard Telecommunication Systems GTS NMS NMS NMS NMS: National Meteorological Service
What kinds of data are exchanged by using GTS? • DBCP: Data Buoy Cooperation Panel (drifting and moored buoys) • SOOP: Ship Of Opportunity Programme (ship board ocean profile data) • VOS data (marine surface meteorological observations)
The Data Buoy Cooperation Panel (DBCP) is a official joint body of WMO and IOC which was formally established in 1985. • It is part of the WMO Marine Programme and is planned for integration within the Global Ocean Observing System (GOOS).
Is this buoy moored or drifting? DRIFTING BUOYS

The primary goal of the Ship-of-Opportunity Programme (SOOP) is to fulfill upper ocean data requirements which have been established by GOOS and GCOS. • The SOOP is directed towards the operational maintenance and co-ordination of the XBT ship of opportunity network but other types of measurements are being made (e.g. TSG, XCTD, CTD, ADCP, pCO2, phytoplankton concentration).

What is VOS programme? • VOS (Voluntary Observing Ship) is a merchant ship which conducts marine surface weather observations on board and send them to NWS on a voluntary basis • NWS provide VOSs with weather forecast/warnings in return National Weather Service (NWS) Voluntary Observing Ship (VOS) observations forecast/warning
These oceanographic data are exchanged by using GTS • Drifting and moored buoy data • Ship board ocean profile data (XBT, XCTD, CTD, etc.) • Marine surface meteorological observations (VOS data)
The broad-scale global array of T/S profiling floats, known as Argo, has already grown to be a major component of the ocean observing system. More than 95% of the target has been performed by August 2007.

What’s NEAR-GOOS • NEAR-GOOS is a regional pilot project of GOOS in the Western Pacific region, presently with the participation of China, Japan, the Republic of Korea and the Russian Federation, with a view to demonstrating the usefulness of a regional ocean observing system within the framework of GOOS.
HISTORY • In November 1993, the General Conference of UNESCO adopted Resolution 57 which called on IOC to establish a GOOS regional pilot activity in the North-East Asian region. • Planning of the regional pilot activity started in 1994 with the participation of China, Japan, the Republic of Korea and the Russian Federation.
In February 1996, a draft implementation plan for NEAR-GOOS was presented at the third session of IOC Sub-Commission for the Western Pacific. • The session decided to establish a Coordinating Committee as a management body for NEAR-GOOS. • The Coordinating Committee finally adopted an implementation plan for the initial phase NEAR-GOOS at its first session in September 1996.
The essence of NEAR-GOOS in its initial phase • To promote free oceanographic data exchange in real time through Internet, in support of daily mapping of sea conditions in marginal seas bordered by NEAR-GOOS participating countries, benefiting a wide range of marine users. • A data exchange system started its operation in 1996.

Summary • Operational Ocean Observing Systems such as buoy network, ship of opportunity and VOS programmes, and Argo have been well developed and maintained under international cooperation. • Buoy network and VOS programme provide surface oceanographic and meteorological observational data. • Argo together with SOOP XBT network provides sub-surface T/S profiles. • All those data are distributed and made available in real-time for operational use.
