Comments: A redetermination of the temperature dependence of the absorption cross section of 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 (3.4x10^13-7.3x10^14 molecules cm-3)
were made at relatively low and high spectral resolutions,
