Abstract
The atmospheric concentration of carbon dioxide (CO2), with its consequences for the greenhouse effect and climate change, is being closely monitored by a variety of space-borne and ground-based remote sensing experiments. These experiments require a relative uncertainty of 0.5 % or better for CO2 line absorption intensities. Here we report a joint experimental and theoretical study providing rotation-vibration line intensities with this precision. The ab initio quantum mechanical calculations are extendible to all atmospherically important bands of CO2 and to its isotopically substituted variants.Citation
