Paper Abstract

Results are presented of an experiment employing a laser source and very high resolution ultraviolet absorption spectroscopy to measure the concentration of OH in a clean environment with a sensitivity limit of about 200,000/cu cm (0.01 pptv), with random noise near 50,000/cu cm. This is a factor of 10 lower than the peak values expected in winter and should easily show the seasonal rise to a summer peak 100 times larger than the sensitivity limit. The experiment is to be run under both (normally) clean tropospheric conditions and during the (occasionally) polluted upslope conditions.
