RISA Method for the Estimate of Broadband Directional Surface Albedo from a Geostationary Satellite
Publisher: American Meteorological Society
Abstract: Surface albedo can be inferred from geostationary satellite measurements as long as the effects due to the atmosphere, the spectral response of the sensor, and the angular anisotropy of the reflected field are corrected. ...
The Relationship between Incident and Double-Way Transmittances: An Application for the Estimate of Surface Albedo from Satellites over the African Sahel
Publisher: American Meteorological Society
Abstract: The inference of surface reflectance from satellite observations requires the knowledge of the double-way transmittance through the atmosphere. Since the existing pyranometer networks routinely provide measurements of the ...
A New Technique for Inferring Surface Albedo from Satellite Observations
Publisher: American Meteorological Society
Abstract: A technique for inferring the spatial and seasonal albodo changes over a whole climatic region from satellite data is developed. This technique uses the diurnal variation of radiances which is measured by geostationary ...
Observation of a Variable Northerly Wind Component in the African Monsoon Layer
Publisher: American Meteorological Society
Abstract: This note describes low-level observations obtained during WAMEX from an instrumented DC 7 aircraft. These data give a detailed description of the dynamical and thermodynamical structure of the layer 0.5?3 km over a zonal ...
A Parameterization of Broadband Conversion Factors for METEOSAT Visible Radiances
Publisher: American Meteorological Society
Abstract: The conversion of radiances measured by the METEOSAT visible channel into broadband radiances can be performed as long as the appropriate conversion factors are known. A simple model allowing a spectral description of the ...
