Calculations of atmospheric refraction are generally based on a simplified model of atmospheric density in the troposphere that assumes the temperature decreases at a constant lapse rate L from sea ...

Large field spectrographs are severely influenced by atmospheric refraction. We discuss the effect of differential refraction across the field as well as the chromatic effects for the Norris ...

Any reference will tell you the Novaya Zemlya effect is a polar mirage — and it is. But Novaya Zemlya-like effects are not limited to the Arctic. The Novaya Zemlya effect is an atmospheric refraction ...

THE correspondence on terrestrial refraction from Mr. Mallock and Dr. de Graaff Hunter in NATURE of June 9, p. 456, and August 11, p. 745, raises a paradox which I think must have puzzled many readers ...

A MONGST the many perplexing problems with which geographical surveyors have to deal those which concern the determination of altitude are not the least. For purposes of practical ability, such as the ...

Meteorologist Zach Maloch captured this morning's gorgeous sunrise from cameras atop the tower atop the WRAL studios on Western Boulevard. The image shows off the Raleigh skyline but also demonstrates ...

GRAND RAPIDS, Mich — Viewers across West Michigan were in awe of the patches of rainbow popping up across the area on Sunday. Sundogs are a result of the refraction of light when the sun's rays ...
