Abstract: To parameterize emissivity of clouds at 11 ?m, a study has been made in an effort to understand the radiation field of thin clouds. The contributions to the intensity and flux from different sources and through different ...

Abstract: A methodology for retrieving the emissivity, cloud cover and cloud top temperature of high-level, thin clouds is developed and described. In the thermal infrared windows, the outgoing radiances from the earth's atmosphere ...

Abstract: Cloud ice water content and cloud geometrical thickness have been determined using a combination of near-infrared, thermal infrared and thermal microwave radiometric measurements. The radiometric measurements are from a ...

Abstract: An algorithm has been developed for using the reflection of solar radiation in the oxygen A-band to determine cloud-top altitude. Because of multiple scattering and molecular absorption inside the cloud, the reflection of ...

Abstract: Orographically-induced lee-wave clouds were observed over New Mexico by a multichannel scanning radiometer on Skylab during December 1973. Channels centered at 0.83, 1.61 and 2.125 ?m were used to determine the cloud optical ...

Abstract: The predictability of the 1997 and 1998 south Asian summer monsoon winds is examined from an ensemble of 10 atmospheric general circulation model simulations with prescribed sea surface temperatures (SSTs) and soil moisture. ...

Abstract: The effect of global cloudiness on the solar and infrared components of the earth's radiation balance is studied in general circulation model experiments. A wintertime simulation is conducted in which the cloud radiative ...

Abstract: his study shows that the African easterly wave (AEW) activity over the African monsoon region and the northern tropical Atlantic can be divided in two distinct temporal bands with time scales of 2.5?6 and 6?9 days. The ...

Abstract: Fourteen years (1980?93) of National Aeronautics and Space Administration reanalysis data are used to document and study the variability in the development of the South Asian summer monsoon associated with the Intraseasonal ...

Abstract: The investigation of fluid flow in fractured rocks is a key issue in underground engineering. Three sandstone specimens with different roughnesses were generated by Brazilian splitting, and the geometric morphology and ...
