Initially this calls for a scientific effort to begin development and make the improvements necessary to frame the observation/analysis system Ultimately the fully scaled system should become operational with a research component to seek continued improvement and relevance See Marquis and Tans (2008), Science 320:460-61, 25 April, for explanation of need for a global verification system. Current ESRL operated Tower and Aircraft network. A likely future scenario may look like the following where sites may be operated jointly with other institutes. We believe ESRL already has the data management strategy and QA/QC infrastructure to ensure that these data will be of the same high-quality that users expect. However, it is likely that in the near future local and regional networks will emerge to monitor CO2 at the state levels. These additional networks are essential if we expect reanalysis tools such as CT to make reliable estimates of emissions at state-level resolution. However, it is absolutely essential that these networks, the ESRL network, and the global cooperative network
