Overall, in 2005 the implementation of surface and upper-air observational programmes in WMO Regions showed stability. While varying from Region to Region, the globally averaged availability of surface reports on the Main Telecommunication Network (MTN) was 78 per cent (77% in 2004) and 70 per cent (67% in 2004) for the upper-air reports expected from Regional Basic Synoptic Network (RBSN) stations. The established Regional Basic Climatological Network (RBCN) in all WMO Regions contributed to the on-going efforts to improve the availability of climatological data. This was underpinned by the CBS/GCOS Training Seminars on Climatological Data reporting.
In accordance with guidance given by Congress and the Executive Council, efforts on the redesign and establishment of a future composite GOS continued and focused on implementation aspects, satellite system utilization and products, requirements and representation of data from Automatic Weather Stations (AWSs), cooperation with GCOS, further integration of AMDAR in WWW operations, and revision of the GOS regulatory material.
The Global Atmosphere Watch (GAW) continued development of its networks, primarily for Essential Climate Variables (ECVs) which are greenhouse gases, ozone and aerosols in support to the United Nations Framework Convention on Climate Change (UNFCCC). In 2006, WMO launched a new products-annual bulletin on GHG. A mechanism for the implementation of an Integrated Global Atmospheric Chemistry Observations (IGACO) was developed and an IGACO-Ozone office was established in Finland.
