Comments: The NO2 absorption cross-section has been measured from 42000 to 10000 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 40000 cm-1 (lambda > 250 nm) at 294 K, 3% below 30000 cm-1 (lambda > 333 nm) at 220 K, but reaches 10% for higher wavenumbers. Temperature and pressure effects have been observed.
