The use of good line parameters and suitable SNR Fourier transform atmospheric spectra has allowed the observation of several atmospheric NO2 absorption peaks and widths corresponding to column densities. The McMath Solar Telescope at Kitt Peak Observatory was employed to take atmospheric spectra in the 2850-2950 kaysers range on Feb. 23, 1981, with a resolution of 0.00979 kayser, and an SNR of 500. The data were found to contain information on the nu-1 plus nu-3 absorption peaks, as well as the hot band nu-1 plus nu-2 plus (nu-3 minus nu-2) features. A total of thirteen features were examined to determine the NO2 column densities at sunrise, early morning, and just before sunset. Densities were 1.84, 1.80, 1.74, and 3.24 x 10 to the 15th molecules/sq cm.
