The Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology

Access to data and services




Ocean Data Portal (ODP)

The Ocean Data Portal (further, ODP) aims at providing seamless access to collections and  inventories of marine data from the NODCs (National Oceanographic Data Centres) of the IODE network and allows for the discovery, evaluation (through visualization and metadata review) and access to data via web services. The ODP has been developed by the "International Oceanographic Data and Information Exchange" (IODE) of the "Intergovernmental Oceanographic Commission" (IOC) of UNESCO. The system architecture use Web-oriented information technologies to access non-homogeneous and geographically distributed marine data and information.



WMO Information System (WIS)

The WMO Information System (WIS) provides for a single coordinated global infrastructure for the collection and sharing of information in support of all WMO and related international programmes. The WIS provides an integrated approach suitable for all WMO Programmes to meet the requirements for routine collection and automated dissemination of observed data and products, as well as data discovery, access and retrieval services for all weather, climate, water and related data produced by centres and WMO Member countries in the framework of any WMO Programme.

It is being built upon the Global Telecommunication System of WMO's World Weather Watch, using standard elements and at a pace feasible for all Members.

The core infrastructure of WIS is comprised of Global Information System Centres (GISCs), Data Collection or Production Centres (DCPCs), and National Centres (NCs).

data-systems Data systems relevant to JCOMM activities

JCOMM-4 charged OPA, in cooperation with the DMPA, to "promote  the establishment and publication of access routes to the authoritative data sets for the observing system elements under its coordination."  There is also "the challenge of data a first step towards developing actions" as articulated by the GOOS Steering Committee.  This report, prepared by R.K. Keeley (retired, and former JCOMM DMPA Coordinator), addresses these challenges in a comprehensive manner, documenting existing practices and making a comprehensive set of recommendations for the community to consider over the coming years to improve the real-time accessibility to data associated with JCOMM OPA activities.

access_3 Real-time ocean and marine meteorology observing network data access

Operational users with access to a national meteorological / hydrological service can access real-time ocean and marine meteorology data on the WMO Global Telecommunications System (GTS).

Research and other users can access real-time and archived data streams from specific observing network and data systems


access_2 Access to ocean and marine meteorological services

The JCOMM Services Programme Area is maintaining a new JCOMM Electronic Product Bulletin (J-EPB) serving as a showcase of available on-line analyses and national services, with a focus on maritime safety, search and rescue, marine pollution and emergency response, sea ice, and waves and storm surges.

For ocean forecasting products, the Global Ocean Data Assimilation Experiment GODAE maintains a list of national and regional efforts:

For ocean synthesis and reanalysis efforts, the CLIVAR Global Synthesis and Observations Panel maintains a list of national and regional efforts:
