| Summary: | In this paper we discuss the methodology of taking broadband relative and
absolute measurements of ozone cross-sections including uncertainty budget,
experimental set-ups, and methods for data analysis. We report on new ozone
absorption cross-section measurements in the solar spectral region using a
combination of Fourier transform and echelle spectrometers. The new
cross-sections cover the spectral range 213–1100 nm at a spectral
resolution of 0.02–0.06 nm in the UV–visible and 0.12–0.24 nm in the IR at
eleven temperatures from 193 to 293 K in steps of 10 K. The absolute
accuracy is better than three percent for most parts of the spectral region
and wavelength calibration accuracy is better than 0.005 nm.

The new room temperature cross-section data are compared in detail with
previously available literature data. The temperature dependence of our
cross-sections is described in a companion paper (Serdyuchenko et al., 2014). |
