| Abstract: |
Every celestial observation made from the ground has to pass through the Earth’s atmosphere, and will at certain wavelengths carry characteristic signatures of atmospheric absorption by the constituent gases. To the professional astronomer the atmosphere is a bane, limiting observing capabilities and driving the development of space missions. Only rarely is the problem inverted, using those signatures in astronomical spectra to extract information about the Earth’s atmosphere. This paper describes how re-analyses of archived historic stellar spectra can offer important information about the Earth’s ozone shield. |
