Abstract

Observations of the vertical column abundance of atmospheric hydroxyl (OH) have been made using a Pepsios (polyetalon pressure-scanned interferometric optical spectrometer). The measurements were taken at both Fritz Peak, Colorado (40°N) and Boca Raton, Florida (26° N) during the period 1985-86. These are high resolution measurements of the resonance absorption of sunlight by OH in the P1(1) A^2 sigma - x^2 pi (0,0) transition at 3081.66 A. The observations are of relevance to the problem of stratospheric ozone reduction by man-made pollution. Attempts to model the photochemistry of the middle atmosphere and to predict its response to these pollutants depend heavily on an accurate observational data base of many middle atmospheric constituents. This OH data base contributes information which is of critical importance to theories describing middle atmospheric processes. The author's measurements are discussed within the context of the ten-year data base accumulated by Dr. Clyde Burnett. Observed geographic and seasonal regularities, as well as short-period excursions in the OH abundances, have not been fully explained by current photochemical theory.
