Description
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.
