WebAug 24, 2016 · In Astronomy, spectral lines which are caused by the Earth's atmosphere and not by the source object being observed, are referred to as Telluric lines (from the latin word tellus meaning Earth). I found this source which describes, in detail, the various telluric lines that you may encounter. Webtelluric line: [noun] any of the absorption lines or bands added to the spectrum of a heavenly body by various substances in the earth's atmosphere.
