RISAn Investigation of Surface Albedo Variations during the Recent Sahel Drought
Publisher: American Meteorological Society
Abstract: Applications Technology Satellite (ATS) 3 green sensor data are used to measure surface reflectance variations in the Sahara/Sahel during the recent drought period 1967?74. The magnitude of the seasonal reflectance change ...
An Unusual Aerial Photograph of an Eddy Circulation in Marine Stratocumulus Clouds
Publisher: American Meteorological Society
Abstract: n aerial photograph of a cyclonic, von Kármán?like vortex in the marine stratocumulus clouds off the California coast, taken by a commercial pilot near Grover Beach, is presented. It is believed that this is the first ...
Over-Ocean Validation of the Global Convective Diagnostic
Publisher: American Meteorological Society
Abstract: The global convective diagnostic (GCD) is a bispectral (infrared and water vapor), day?night scheme for operationally mapping deep convection by means of geostationary satellite images. This article describes a test of GCD ...
A Model for Calculating Desert Aerosol Turbidity over the Oceans from Geostationary Satellite Data
Publisher: American Meteorological Society
Abstract: A technique has been developed to infer the optical thickness of Saharan dust from Synchronous Meteorological Satellite (SMS) brightness measurements at visible wavelengths. The scattering model consists of an air layer, ...
The Identification and Verification of Hazardous Convective Cells over Oceans Using Visible and Infrared Satellite Observations
Publisher: American Meteorological Society
Abstract: Three algorithms based on geostationary visible and infrared (IR) observations are used to identify convective cells that do (or may) present a hazard to aviation over the oceans. The performance of these algorithms in ...
