Abstract:
An analytical model δ(sur) is suggested for nitrogen and oxygen shift coefficients of water vapor in the visible region. The model δ(sur) linearly depends on the broadening coefficient of a given line and fitted parameters. The analysis of the available experimental data on d coefficients for the near infrared and visible regions is performed. The model δ(sur) retrieves 486 nitrogen shift coefficients for lines from the range 13550–22590 cm-1 with a mean square deviation of 6.0 × 10-3 cm-1/atm and oxygen shift coefficient for lines from the range 13550–14000 cm-1 with a mean square deviation of 2.5 × 10-3 cm-1/atm.
