Infrared spectroscopic measurements of tropospheric trace gases.

Absorption features of several trace gases have been detected in 0.017-cm -(1)-resolution infrared spectra recorded over surface-level paths of 0.5 and 1.5 km at the National Solar Observatory on Kitt Peak, near Tucson, Arizona. Measurements of 0(3), HCOOH, NH(3), and H(2)CO are briefly discussed.
