Advances in Space Research, 1986 Abstract At infrared wavelengths many thin, low mass dust clouds are observed at high galactic latitudes. In this paper a number of observations, including optical observations related to these “cirrus” clouds are discussed. The clouds are excellently suitable for studies of grain properties and of the surrounding radiation field.

Identification of Cirrus over Wausau during the 1986 FIRE IFO from ground-based radiometer data [PDF]
The potential of using irradiation data to indicate episodes of cirrus cloudiness during the daylight hours is explored. Thresholds separating cirrus from other clouds and clear skies are determined using four days of irradiation data, hourly weather ...

Multi-spectral window radiance observations of Cirrus from satellite and aircraft, November 2, 1986 Project FIRE [PDF]
High resolution infrared radiance spectra achieved from the NASA ER2 airborne HIS experiment are used to analyze the spectral emissivity properties of cirrus clouds within the 8 to 12 micron atmospheric window region.

Cumulus, cirrus, stratus [PDF]
Géographie et cultures, 2013 D’où viennent les noms des nuages, qui nous sont, pour les formes simples (cirrus, cumulus, stratus), si familiers ? C’est un pharmacien anglais, Luke Howard, qui les inventa au début du XIXe siècle dans On the modifications of clouds. Cet article est centré sur la classification de Howard et son histoire : d’abord, les premières tentatives de ...

Cirrus parameterization from the FIRE ER-2 observations [PDF]
Primary goals for the FIRE field experiments were validation of satellite cloud retrievals and study of cloud radiation parameters. The radiometers and lidar observations which were acquired from the NASA ER-2 high altitude aircraft during the FIRE ...

Cirrus cloud model parameterizations: Incorporating realistic ice particle generation [PDF]
Recent cirrus cloud modeling studies have involved the application of a time-dependent, two dimensional Eulerian model, with generalized cloud microphysical parameterizations drawn from experimental findings.
