Ozone absorption around 10 μm

Abstract

[1] A careful comparison of four sets of ozone line intensities measured independently in the 10 mm region has been achieved. It is demonstrated that three of the experimental sets agree to better than 2% whereas the last one is consistently 4.4% higher. This is also the case for the ozone line intensities given in the HITRAN database, which are about 4% higher than the values given in the three experimental sets in agreement. New and more accurate transition moment constants for the n 1 and n 3 bands of 16 O 3 were derived and used to generate new line positions and intensities. These new spectroscopic parameters allow one to simulate atmospheric spectra recorded by the Atmospheric Trace Molecule Spectroscopy Experiment better than the existing HITRAN spectroscopic parameters, showing that on a relative basis the new spectral parameters are of better quality.

The HITRAN 2004 molecular spectroscopic database

“…The transition moment parameters of Ref. [128] for {(101),(030)}-(010) bands and those extrapolated from cold bands [141] were used. (213), (321) and (114) upper states.…”

MIPAS: an instrument for atmospheric and climate research

“…The first version "mipas pf2.0" was based on both the 1996 version of HITRAN and on new laboratory spectroscopic data and new calculations (Flaud et al, 2003a;Flaud et al, 2003b). After launch, version "mipas pf3.1" of the MIPAS dedicated spectroscopic database was released.…”

A new photometric ozone reference in the Huggins bands: the absolute ozone absorption cross section at the 325 nm HeCd laser wavelength

“…The atmospheric comparison of Kagawa et al (2007) between concentrations from TOMS (UV) and from ground-based FTS (IR) does not directly depend on the intensities in the ν 1 fundamental. But the fact that most atmospherically relevant ozone vibrational intensities in HITRAN directly depend on transition moments of the ν 1 and ν 3 fundamentals implies that IR intensities in the 3 µm region should be corrected by the same amount (Rothman et al, 2005;Flaud et al, 2003), implying that the discrepancy observed in their study is resolved at the same time.…”
