This landscape is a good example of aerial perspective; however, it is not an aerial landscape, since apparently, the observer is standing on the ground.) As such, the term atmospheric perspective can be understood to better describe how properties of the scene's atmosphere effect the appearance of an object as it moves further from the viewer.
Original – Atmospheric perspective, or aerial perspective, is the effect caused by the atmosphere on the appearance of objects observed by a viewer.As the distance between the object and the viewer increases, the contrast decreases and the colours become lighter and more bluish, until the image of the object eventually fades into the sky.
Atmospheric optics is "the study of the optical characteristics of the atmosphere or products of atmospheric processes .... [including] temporal and spatial resolutions beyond those discernible with the naked eye". [1] Meteorological optics is "that part of atmospheric optics concerned with the study of patterns observable with the naked eye". [2]
The technique was used not only to give an elusive and illusionistic rendering of the human face, but also to create rich atmospheric effects. Leonardo da Vinci described the technique as blending colours, without the use of lines or borders "in the manner of smoke".
The curvature of the horizon is easily seen in this 2008 photograph, taken from a Space Shuttle at an altitude of 226 km (140 mi).. The horizon is the apparent curve that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body.
For example, when α is the ground plane and β is the horizon plane, then the vanishing line of α is the horizon line β ∩ π. To put it simply, the vanishing line of some plane, say α , is obtained by the intersection of the image plane with another plane, say β , parallel to the plane of interest ( α ), passing through the camera center.
The infrared atmospheric window is an atmospheric window in the infrared spectrum where there is relatively little absorption of terrestrial thermal radiation by atmospheric gases. [1] The window plays an important role in the atmospheric greenhouse effect by maintaining the balance between incoming solar radiation and outgoing IR to space.
Atmospheric windows are useful for astronomy, remote sensing, telecommunications and other science and technology applications. In the study of the greenhouse effect, the term atmospheric window may be limited to mean the infrared window, which is the primary escape route for a fraction of the thermal radiation emitted near the surface.
