Atmospheric remote-sensing reference data from GOME:: Part I.: Temperature-dependent absorption cross-sections of NO2 in the 231-794 nm range

Absorption cross-sections of NO2 between 231-794 nm have been measured in the 221-293 K temperature range, using the global ozone monitoring experiment (GOME) flight-model (FM) satellite spectrometer. The spectra have a resolution of about 0.2 nm below 400 nm and of about 0.3 nm above 400 nm. These are the first reference spectra of NO2 covering at the same time the entire UV-visible-NIR spectral range and a broad range of relevant atmospheric temperatures. The new absorption cross-sections are important as accurate reference data for atmospheric remote-sensing of NO2 and other minor trace gases. (C) 1998 Elsevier Science Ltd. All rights reserved.
