WebThe Hyperspectral Infrared Atmospheric Sounder (HIRAS) onboard the Feng Yun-3D (FY-3D) satellite is the first Chinese hyperspectral infrared instrument. In this study, an improved cloud detection scheme using brightness temperature observations from paired HIRAS long-wave infrared (LWIR) and short-wave infrared (SWIR) channels at CO2 absorption … WebSimulated data showed that cirrus clouds could lead to a maximum land surface temperature (LST) retrieval error of 11.0 K when using the generalized split-window (GSW ...
Cirrus Clouds - an overview ScienceDirect Topics
WebCirrus clouds are thin, wispy clouds that are generally located in the upper troposphere and lower stratosphere (cloud top pressure < 440 hPa and ice phase) and have a major influence on the radiation budget of the Earth’s climate system [1–3]. WebCirrus clouds are globally distributed, being present at all latitudes and without respect to land or sea or season of the year. They undergo continuous changes in area coverage, thickness, ... detected at stations in the midwestern and northwestern United States that are located beneath the major upper tropospheric flight paths.

Solar Absorption by Cirrus Clouds and the Maintenance of the
Webcirrus meaning: 1. a type of light, feathery cloud that is seen high in the sky 2. a type of light, feathery cloud…. Learn more. Cirrus (cloud classification symbol: Ci) is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands. Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes. Globally, they form … See more Cirrus are wispy clouds made of long strands of ice crystals that are described as feathery, hair-like, or layered in appearance. First defined scientifically by Luke Howard in an 1803 paper, their name is derived from the See more Cirrus clouds cover up to 25% of the Earth (up to 70% in the tropics at night ) and have a net heating effect. When they are thin and translucent, the clouds efficiently absorb outgoing See more Cirrus clouds can produce several optical effects like halos around the Sun and Moon. Halos are caused by interaction of the light with hexagonal ice crystals present in the clouds which, depending on their shape and orientation, can result in a wide variety of … See more Cirrus clouds are usually formed as warm, dry air rises, causing water vapor to undergo deposition onto rocky or metallic dust particles at high altitudes. The average cirrus … See more Random, isolated cirrus do not have any particular significance. A large number of cirrus clouds can be a sign of an approaching See more Scientists have studied the properties of cirrus using several different methods. Lidar (laser-based radar) gives highly accurate information on the cloud's altitude, length, and … See more Cirrus clouds are one of three different genera of high-level clouds, all of which are given the prefix "cirro-". The other two genera are cirrocumulus and cirrostratus. High-level clouds usually form above 6,100 m (20,000 ft). Cirrocumulus and cirrostratus are … See more WebCirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, … high output towel rail
