Our primary research interest is high-resolution molecular spectroscopy of atmospheric species in support of Earth and (Exo)Planetary Science. It includes, but not limited to, (1) spectral data acquisition and analysis of rotational and vibrational molecular transitions in the infrared and near-visible region using a state-of-the-art Fourier transform spectrometer (FTS) stationed at JPL, as well as the existing spectral data archive from the McMath-Pierce FTS at the Kitt Peak National Solar Observatory, (2) characterization of the spectroscopic line parameters and/or their cross-sections for atmospheric molecules, such as CH₄, NH₃, hydrocarbons (CxHy), and nitriles(CxHyNz), in a wide temperature range (80 - 1000K), (3) measurements of collision-induced absorption as additional atmospheric opacity source, and (4) precision-modeling of telluric absorption features to enable the extreme precision radial velocity (EPRV) measurements in search of Earth-analogs in the habitable zone (HZ). We produce spectral references and calibration data for Earth atmospheric trace gases and for elusive molecules for Titan and cold giant planets. Measurements from our group are currently used by various NASA missions (e.g. Orbiting Carbon Observatory (OCO), Cassini/CIRS, IRTF/NIRSPEC) as well as the HITRAN molecular spectroscopy database.
