ABSTRACT
We report on the temperature dependence of ozone absorption cross-sections measured in our laboratory in the spectral range 213–1100 nm with a spectral resolution of 0.02–0.24 nm (Full Width Half Maximum, FWHM) in the atmospherically relevant temperature range from 193 to 293 K. The temperature dependence of ozone absorption cross-sections was established using measurements at eleven temperatures. The methodology of the absolute broadband measurements, experimental procedures and spectra processing were described in our companion paper together with the associated error budget. In this paper, we report in detail on our data below room temperature and compare them with literature data using direct comparisons as well as the standard approach using a quadratic polynomial in temperature fitted to the cross-section data.
