Contributions of argon, nitrogen, and oxygen to air broadening in the oxygen A-band

April 16, 2025
Author(s)
Leah Stevenson, Mitchio Okumura, Joseph Hodges, Erin Adkins
The oxygen (O2) A-band is used to determine the air mass in ground- and space-based remote sensing measurements because the O2 mixing ratio in Earth's atmosphere is constant. Because errors in the retrieved air mass propagate to measurements of target gas

Piotr Wcislo, N. Stolarczyk, M. Slowinski, H. Jozwiak, Daniel Lisak, R. Ciurylo, A. Cygan, F. Schreier, C.D. Boone, A. Castrillo, L. Gianfrani, Y. Tan, S-M. Hu, Erin Adkins, Joseph Hodges, H. Tran, H.N. Ngo, J.M- Hartmann, A. Campargue, S. Beguier, R.J. Hargreaves, L.S. Rothman, I.E. Gordon
Parameters associated with the collisional perturbation of spectral lines are essential for modeling the absorption of electromagnetic radiation in planetary atmospheres. The HITRAN molecular spectroscopic database provides these parameters, although

An Accurate Determination of O2 A-band Line Intensities through Experiment and Theory

February 27, 2025
Author(s)
Erin Adkins, Sergei Yurchenko, Wilfrid Somogyi, Joseph Hodges
Accurate intensities of the O2 A-band 〖[b〗^1 Σ_g^+⟵X^3 Σ_g^- (0,0)] centered about 760 nm are essential to reduce biases in satellite- and ground-based remote measurements of column-integrated air mass and greenhouse gas concentration. In support of these

Improvement of the spectroscopic parameters of the air- and self-broadened N2O and CO lines for the HITRAN2020 database applications

June 11, 2021
Author(s)
Robab Hashemi, Iouli Gordon, Erin Adkins, Joseph T. Hodges, Manfred Birk, David Long, Chris Boone, Adam Fleisher, Adriana Predoi-Cross, Laurence Rothman
This paper outlines the major update of the line-shape parameters that were performed for the nitrous oxide (N2O) and carbon monoxide (CO) molecules listed in the HITRAN2020 database. We reviewed the collected measurements for the air- and self-broadened
