摘要

Remote sensing of CO_2 requires high-fidelity reference data of spectral line parameters to be successful. The 6360 cm~(-1) region is commonly used by satellites, field campaigns, and point-source gas sensors because it contains well-characterized and relatively isolated transitions of appropriate line strengths for atmospheric applications. However, the presence of gases other than CO_2, N_2, and O_2 can be a source of uncertainty for atmospheric measurements. Near 6360 cm~(-1), there are numerous H_2O and HDO transitions. Water makes up approximately 1-4% of Earth's lower atmosphere and can interfere with remote sensing measurements by (1) appearing as a direct spectral interference or (2) acting as a foreign broadener for CO_2 lines. The primary goal of this work was to quantify H_2O broadening of CO_2 through precision spectroscopy measurements on the R16e transition at 6359.967 cm ~(-1) and its two nearest neighbors. A secondary goal was to assess the accuracy of H_2O reference line parameters in the HITRAN 2008 database for spectrally removing typical levels of moisture from air samples containing approximately 400 ppm of CO_2.
