Atmospheric remote-sensing reference data from GOME -: 2.: Temperature-dependent absorption cross sections of O3 in the 231-794 nm range

Absorption cross sections of O-3 in the 231-794 nm range have been measured at temperatures between 202 and 293 K using the Global Ozone Monitoring Experiment (GOME) Flight-Model(FM) satellite spectrometer. The GOME FM spectra have a spectral resolution of about 0.2 nm below 400 nm and of about 0.3 nm above 400 nm, and were recorded covering simultaneously the Hartley Huggins, and Chappuis bands centered around 255, 340, and 610 nm, respectively. The variation of the O-3 absorption cross sections was investigated over the entire spectral range 231-794 nm. The new cross sections are important as reference data for atmospheric remote-sensing of O-3 and other trace gases. (C) 1999 Elsevier Science Ltd. All rights reserved.
