摘要：

The vertical column abundance of NO2 is measured using direct sunlight. The solar spectra in the wavelength region of 430–450 nm observed from the earth’s surface are ratioed with a reference spectrum taken from the Kitt Peak Solar Flux Atlas. The large Fraunhofer features (20–40%) are eliminated by wavelength correction, resolution matching and ratioing of observed spectra to the reference. The retrieved values of the NO2 vertical column density are in a range of (2–15)x1016 molecules/cm2 with an accuracy of better than 3%. This result demonstrates the usefulness of the Kitt Peak Atlas in the study of tropospheric NO2 concentration, giving a standard extraterrestrial solar spectrum for the case in which the Langley method is not readily applicable. © 1997, The Optical Society of Japan.
