IODE Global Data Assembly Centres (GDACs)

Objective

The IODE Global Data Assembly Centres (GDACs), as a structural element of IODE, will contribute to the Marine Climate Data System (MCDS), established by JCOMM-4 (2012). The Terms of Reference of the GDACs are as follows:

1. receive and assemble marine meteorological and/or oceanographic data (real or delayed-mode) and metadata from the appropriate data streams and check the are consistent;
2. identify duplicates and if possible resolve by keeping the best copy of a dataset;
3. make sure that the data are quality controlled according to the international standards and methods established by IODE, WMO or JCOMM as appropriate;
4. provide feedback to the sources of data regarding quality issues;
5. make data accessible through IODE/ODP;
6. make discovery metadata available to IODE/ODP;
7. forward data and metadata to the appropriate CMOC(s) in agreed format(s) within defined timescales;
8. contribute to WMO and IOC Applications by collecting and processing worldwide marine-meteorological and oceanographic data and metadata documented in appropriate WMO and IOC publications;
9. report to the IODE and JCOMM Committees on its data management status and activities.Establishment

Establishment

The IODE GDACs were established a structural elements of IODE by the IODE Committee at its 22nd Session, through Recommendation IODE-XXII.13:

Recommendation IODE-XXII.13

IODE GLOBAL DATA ASSEMBLY CENTRES (IODE GDACs)

The IOC Committee on International Oceanographic Data and Information Exchange,

Acknowledging the importance of close collaboration between IODE and JCOMM,

Recalling the usefulness of the former IODE RNODC/Data Buoys collecting, managing and making available historical drifting buoy data and metadata to end user,

Recalling the establishment of the Marine Climate Data System (MCDS) by JCOMM-4 through Recommendation 2 (JCOMM-4), to address the WMO and IOC applications requirements for appropriate marine-meteorological and oceanographic climatological data (met-ocean climate data), and particularly address those for long term climate monitoring (GCOS), seasonal to inter-annual climate forecasts, for the Global Framework for Climate Services (GFCS), and ocean climate requirements of the Global Ocean Observing System (GOOS),

Complying with the proposed MCDS structure it is advantageous to IODE to introduce the element of GDACs in the IODE structure,

Recommends that IODE GDACs be included as structural elements of IODE with the following Terms of Reference with respect to particular data types:

1.  receive and assemble marine meteorological and/or oceanographic data (real or delayed-mode) and metadata from the appropriate data streams and check the are consistent;
2.  identify duplicates and if possible resolve by keeping the best copy of a dataset;
3.  make sure that the data are quality controlled according to the international standards and methods established by IODE, WMO or JCOMM as appropriate;
4.  provide feedback to the sources of data regarding quality issues;
5.  make data accessible through IODE/ODP;
6.  make discovery metadatato IODE/ODP;
7.  forward data and metadata to the appropriate CMOC(s) in agreed format(s) within defined timescales;
8.  contribute to WMO and IOC Applications by collecting and processing worldwide marine-meteorological and oceanographic data and metadata documented in appropriate WMO and IOC publications;
9.  report to the IODE and JCOMM Committees on its data management status and activities.

Invites the IODE structural elements either individually or jointly to operate as IODE provisional GDACs and apply to become a GDAC, when the procedures for doing so are established.
