Tunable diode laser laboratory measurements of infrared spectral parameters of selected NO{sub 2} lines near 1,600 cm{sup {minus}1} have been made to assess the contribution of uncertainties in these parameters to stratospheric measurements of NO{sub 2} made using the Balloon-born Laser In-Situ Sensor (BLISS) tunable diode laser spectrometer. Relative line intensities are measured to accuracies of better than 2%, with a root-sum-squared uncertainty in the absolute linestrengths of 4.5%. Air broadening coefficients have been determined from measurements at total pressures in the range 20-100 Torr, at temperatures of 293 K and 214 K. These results are also discussed in the light of the discrepancies between infrared instruments flown in the 1982 and 1983 Balloon Intercomparison Campaigns.
