Structure of WMO/GAWGAW consists of national meteorological/hydrologica l services and other partners contributing to observing system s, experts groups and central facilities, and the secretariat.


To enhance the present GTS network, to facilitate information and data exchanges for all WMO programmes.

CO2 Calibration Scales at the WDCGG

� More than 90% of the CO 2 data sets reported to the WDCGG are on the WMO or NOAA scale, but different scales exis t.

� The WDCGG encourages contributors to submit data in latest WMO scales (WMO X2007 scale or whatever the latest scale is).

Summary

24

�WDCGG started newly designated WMO WIS/DCPC service from 1st Aug. 2011 onward. We expect that metadata from WDCGG are delivered together with all other WMO data catalogues and facilitate the data exchange within all WMO programs and beyond them.

� Minor extensions of WDCGG website were implemented. There still exists many demands for WDCGG from both contributors and users.

� Further efforts will be made for value-added information and functions within the GAW data policy and our capacity.

� Web server for WDCGG, QA/SAC and WCC websites will be replaced in next March. We would not change our services but URL expected to be changed. We will keep you informed on upcoming details via WDCGG web.


Thank you for your attention!
