Abstract: Observations of the physical properties of Arctic status clouds (ASC) over the Beaufort Sea area were made by the NCAR Electra aircraft during June 1980. The cloud morphology and microstructure observed during these ...

Abstract: A radiation model is constructed that includes radiative interactions with atmospheric gases as well as parameterized treatments of scattering and absorption/emission by cloud droplets and haze particles. A unified treatment ...

Abstract: Clear sky ice crystals or diamond dust displays are observed in polar regions, both remote and populated; when the temperature falls to ?20°C and where abundant sources of water vapor are present. In remote areas of the ...
