Since then, satellite reading of temperatures and the occlusion of numerous infrared bands, ground based, aircraft and balloon measurements of same, and an ever - increasing data base of the optical properties of CO2 (and other gases, like water vapour), have helped refine radiation calculations towards determining the atmospheric heat budget.

Also, while we have good atmospheric measurements of other key greenhouse gases such as carbon dioxide and methane, we have poor measurements of global water vapor, so it is not certain by how much atmospheric concentrations have risen in recent decades or centuries, though satellite measurements, combined with balloon data and some in - situ ground measurements indicate generally positive trends in global water vapor.»
