The NO2 absorption cross-section has been measured from 42 000 to 10 000 cm-1 (238-1000 nm) with a Fourier transform spectrometer (at the resolution of 2 cm-1, 0.01 nm at 240 nm to 0.2 nm at 1000 nm) and a 5 m temperature controlled multiple reflection cell. The uncertainty on the cross-section is estimated to be less than 3% below 40 000 cm-1 (λ > 250 nm) at 294 K, 3% below 30 000 cm-1 (λ > 333 nm) at 220 K, but reaches 10% for higher wavenumbers. Temperature and pressure effects have been observed. Comparison with data from the literature generally shows a good agreement for wavenumbers between 37 500 and 20 000 cm-1 (267-500 nm). Outside these limits, the difference can reach several percent.
