Atmospheric optics wavelengths. A halo (ἅλως; also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by the interaction of light from the sun or moon with ice crystals in the atmosphere, resulting in colored or white arcs, rings or spots in the sky. Many halos are positioned near the sun or moon, but others are elsewhere and even in the opposite part of the sky. They can also form around artificial lights in very cold weather when ice crystals called diamond dust are floating in the nearby air. There are many types of ice halos. They are produced
Nimbus 5 malfunctioned soon after launch. THIR was for measuring cloud top temperatures and water vapor content in the stratosphere. It could measure cloud temperatures in the day and at night. The sensing unit was a bolometers made from germanium. Nimbus 5 Nimbus 5 (also called Nimbus E or Nimbus V) was a meteorological satellite for research and development of sensing technology. It was the fifth successful launch in a series of the Nimbus program. The objective of Nimbus 5 was to test and evaluate advanced sensing technology, and to provide improved photographs of cloud formations. Nimbus 5 was launched on December
