As a principal constituent, the molecule is also important in studies of the atmospheres of Venus and Mars. , To obtain accurate CO 2 information from observational data, high-precision line parameters of CO 2 in the infrared region, especially in the 1.6 μm region where the commonly used 3001(2,3)e–00001e bands of 12 C 16 O 2 are located, are increasingly required for various missions and remote sensing programs.…”

Accurate spectroscopic data of carbon dioxide are widely used in many important applications, such as carbon monitoring missions. Here, we present comb-locked cavity ringdown saturation spectroscopy of the second most abundant isotopologue of CO 2 , 13 C 16 O 2 . We determined the positions of 88 lines in three vibrational bands in the 1.6 μm region, 30011e/ 30012e/30013e−00001e, with an accuracy of a few kHz. Based on the analysis of combination differences, we obtained for the first time the ground-state rotational energies with kHz accuracy. We also provide a set of hybrid line positions for 150 13 C 16 O 2 transitions. The rotational energies (J < 50) in the 30013e vibrational state can be fitted by a set of rotational and centrifugal constants with deviations within a few kHz, indicating that the 30013e state is free of perturbations. These precise isotopic line positions will be utilized to improve the Hamiltonian model and quantitative remote sensing of carbon dioxide. Moreover, they will help to track changes in the carbon source and sink through isotopic analysis.

Carbon dioxide () emissions from combustion sources are uncertain in many places across the globe. Here, we estimate emission rates from a small number of collocated observations from the Orbiting Carbon Observatory‐3 (OCO‐3) and the Earth Surface Mineral Dust Source Investigation (EMIT), both onboard the International Space Station (ISS). These near‐simultaneous measurements allow for an unprecedented comparison of two unique space‐based sensors over both isolated coal‐fired power plants and multi‐source scenes in China. We estimate emission rates using integrated mass enhancement and a Gaussian plume model. Where validation data is available, 15 of the 19 estimated emission rates have errors less than 37%. For the multi‐source scenes, EMIT can estimate emissions from individual facilities but its aggregate emissions are 42% lower than OCO‐3, likely because it cannot detect small sources or diffuse emissions. OCO‐3, with its excellent precision, may better constrain emissions over the entire scene.
