The air-broadening coefficients of HO2

Yan Tan; Roman V. Kochanov; Laurence S. Rothman; Iouli E. Gordon*

The air-broadening coefficients for HO2 in HITRAN were updated since different measurements have recently been made in infrared and submillimeter-wave spectral regions. The semi-empirical procedure we developed is described in this report and corresponding HO2 file in the traditional 160 character format is provided.
