text: Space-based measurements of carbon dioxide are also a recent addition to atmospheric X measurements. SCIAMACHY aboard ESAs ENVISAT made global column X measurements from 2002 to 2012. AIRS aboard NASAs Aqua satellite makes global X measurements and was launched shortly after ENVISAT in 2012. More recent satellites have significantly improved the data density and precision of global measurements. Newer missions have higher spectral and spatial resolutions. JAXAs GOSAT was the first dedicated GHG monitoring satellite to successfully achieve orbit in 2009. NASAs OCO-2 launched in 2014 was the second. Various other satellites missions to measure atmospheric X are planned.
