KnowraAtmospheric extinctionLinked fromLinked fromThe 8 pages that link to Atmospheric extinction, each with the reason it gives.All 8Related 6Compared with 2Interstellar extinctionCompared with: It affects ground-based observations but arises in Earth’s air, not interstellar matter.Solar irradianceRelated: It accounts for sunlight lost between the top of the atmosphere and the ground.Astronomical seeingCompared with: Extinction dims sources; seeing redistributes their image across neighboring directions.VisibilityRelated: Extinction dims distant objects and reduces the contrast that makes them recognizable.Photometric systemRelated: Ground-based measurements must correct the atmosphere’s effect on each band.Naked-eye astronomyRelated: It makes objects near the horizon look fainter and can alter their apparent color.Astronomical filterRelated: Atmospheric transmission changes the effective response of ground-based filters.UBV photometric systemRelated: Ground-based UBV observations require corrections for the atmosphere’s unequal absorption across bands.
