A technique using a stellar spectrographic plate to measure terrestrial ozone column depth.

摘要

This thesis examines the feasibility of a technique to extract ozone column depths from photographic stellar spectra in the 5000-7000 Angstrom spectral region. A stellar spectrographic plate is measured to yield the relative intensity distribution of a star's radiation after transmission through the earth's atmosphere. The amount of stellar radiation absorbed by the ozone Chappuis band is proportional to the ozone column depth. The measured column depth is within 10% the mean monthly value for latitude 36
