RISInformation Content of AVHRR Channels 4 and 5 with Respect to the Effective Radius of Cirrus Cloud Particles
Publisher: American Meteorological Society
Abstract: This paper investigates the important difference in the relationship between brightness temperatures between the 11-?m and the 12-?n AVHRR data and the microphysical properties of the semitransparent cirrus clouds. In the ...
Observations of Saharan Aerosols: Results of ECLATS Field Experiment. Part II: Broadband Radiative Characteristics of the Aerosols and Vertical Radiative Flux Divergence
Publisher: American Meteorological Society
Abstract: The results presented in this paper are a part of those obtained during the ECLATS experiment The broadband radiative characteristics of the Sahelian aerosol layer and the vertical radiative flux divergence within the dust ...
Observations of Saharan Aerosols: Results of ECLATS Field Experiment. Part I: Optical Thicknesses and Aerosol Size Distributions
Publisher: American Meteorological Society
Abstract: A series of ground-based and airborne observations of desert aerosols, the ECLATS experiment was carried out in December 1980 in the vicinity of Niamey (Niger). This paper deals with aerosol optical thicknesses and size ...
The Potential of Infrared Satellite Data for the Retrieval of Saharan-Dust Optical Depth over Africa
Publisher: American Meteorological Society
Abstract: Optical depth of Saharan dust derived from photometric measurements made during the dry season at a Sahelian site (Niamey, Republic of Niger) is compared with METEOSAT-2 radiance in the 10.5?12.5 ?m channel for different ...
Large-Scale Analysis of Cirrus Clouds from AVHRR Data: Assessment of Both a Microphysical Index and the Cloud-Top Temperature
Publisher: American Meteorological Society
Abstract: An algorithm that allows an automatic analysis of cirrus properties from Advanced Very High Resolution Radiometer (AVHRR) observations is presented. Further investigations of the information content and physical meaning ...
Assessing 1D Atmospheric Solar Radiative Transfer Models: Interpretation and Handling of Unresolved Clouds
Publisher: American Meteorological Society
Abstract: The primary purpose of this study is to assess the performance of 1D solar radiative transfer codes that are used currently both for research and in weather and climate models. Emphasis is on interpretation and handling ...
