Detailed Description

Tabulates the absorption cross section of NO2 molecules at medium resolution (0.2-0.33 nm) from 230 nm to 795 nm at 4 temperatures. The cross-sections were measured by Burrows et al. with the GOME instrument before flight.

Spectral resolution
  • 231-307 nm, 0.20 nm (FWHM ?)
  • 307-316 nm, 0.20 nm
  • 311-405 nm, 0.17 nm
  • 405-611 nm, 0.29 nm
  • 595-794 nm, 0.33 nm
Temperature Range
The cross-sections were measured at 4 temperatures covering normal stratospheric and tropospheric ranges. The paper does not provide any advice on how to interpolate in temperature. We use the standard (linear interpolation) technique provided by the base class. The spectra were measured at the following four temperatures.
  1. 221K
  2. 241K
  3. 273K
  4. 293K

Paper Abstract
Absorption cross-sections of NO2 between 231-794 nm have been measured in the 221-293K temperature range, using the global ozone monitoring experiment (GOME) flightmodel (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.
