Abstract

The near-infrared bands of carbon dioxide (CO$_{2}$) play an important role in point source as well as remote sensing measurements. Here we have measured high accuracy line intensities for the (30012)$\leftarrow$(00001), (30013)$\leftarrow$(00001), and (30014)$\leftarrow$(00001) bands near 1.6 $\mu$m. Three separate cavity ring-down spectrometers were employed: a frequency-agile, rapid scanning spectrometer and two frequency-stabilized spectrometers. Through this combination of instruments, we have reached relative combined standard uncertainties as low as 0.1$\%$ for the band intensities. I will discuss these measurements as well as comparisons to existing spectroscopic models and databases. Finally, I will present the results of atmospheric retrievals using these line intensities.
