Description
Spectroscopic observations were made of the resonance absorption of
sunlight by the atmospheric hydroxyl radical (OH). The abundance of
0 terrestrial OH was measured from the Fritz Peak Observatory (39.92 N,
105.50°W) in Colorado during September of 1978. These measurements
were made on the absorption of the P1 (1) line of the A^2sigma^+ - x^2pi(O , O)
rotational band of OH at 3081.7 A. The instrument used was the
PEPSIOS (Poly Etalon Pressure Scanned Interferometric Optical Spectrometer)
because of its high luminosity - resolution product . The
computer methods ·~sed in the analysis procedure are described . These
measurements indicated an average daytime vertical column abundance
of (5.40 ± 0.67) x 10^13 OH molecules/cm^2.
