A redetermination of the temperature dependence of the absorption cross section (&sgr;) for NO2 in the visible-ultraviolet region (264--649 nm) has been made in order to provide a more reliable data base for the calculation of NO2 photolysis rates in the atmosphere. Experiments over a wide range of temperatures (-40.6¿ to 124¿C) and NO2 concentrations (3.4¿1013-7.3¿1014 molecules cm-3) were made at relatively low and high spectral resolutions, employing diode array and Fourier transform spectrometers, respectively. There are three aspects of the temperature dependence which were noted: (1) the integral of a plot of &sgr; versus 1/λ&sgr; (264-649 nm) was essentially independent of temperature; (2) increasing temperature produced a shift of the spectrum toward longer wavelengths, in a small negative temperature dependence of &sgr; over the 264-- to 400-nm range and a small positive dependence over the 450-- to 649-nm range; (3) increasing temperature produced broadening of individual spectral features, resulting in a systematic lowering of peaks and filling of valleys. Recommended cross sections, averaged over 5-nm wavelength intervals, are presented for use in tropospheric NO2, photolysis rate calculations. ¿ American Geophysical Union 1988
