NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) archives and distributes pioneeringcollections of data on atmospheric greenhouse gases. In September of 2012, the Atmospheric Infrared Sounder (AIRS)marked a decade of tropospheric observations of carbon dioxide $(\hbox{CO}_{2})$. Most recently, the Atmospheric $\hbox{CO}_{2}$ Observations from Space (ACOS) project and GES DISCreleased $\hbox{CO}_{2}$ retrievals derived from radiances observed by theJapanese Greenhouse gases Observing SATellite (GOSAT) satellite, launched in 2009. In this letter, we present the mostrecent estimates of decadal mid-tropospheric trends of $\hbox{CO}_{2}$ from AIRS, as well as the most recent status of thetotal column-average distribution of $\hbox{CO}_{2}$ from ACOS. We also demonstrate that significantdiscrepancies still exist in the global distribution of observed and modeled column amounts of $\hbox{CO}_{2}$ using the $\hbox{CO}_{2}$ retrievals from the ACOS project.
