RISA Fast Line-by-Line Method for Atmospheric Absorption Computations: The Automatized Atmospheric Absorption Atlas
Publisher: American Meteorological Society
Abstract: A computationally fast line-by-line method for the determination of atmospheric absorption is described. This method is based on the creation of an Automatized Atmospheric Absorption Atlas (4A) covering all possible plausible ...
Infrared Continental Surface Emissivity Spectra Retrieved from AIRS Hyperspectral Sensor
Publisher: American Meteorological Society
Abstract: Atmospheric Infrared Sounder (AIRS; NASA Aqua platform) observations over land are interpreted in terms of monthly mean surface emissivity spectra at a resolution of 0.05 ?m and skin temperature. For each AIRS observation, ...
A Single-Channel, Double-Viewing Angle Method for Sea Surface Temperature Determination from Coincident METEOSAT and TIROS-N Radiometric Measurements
Publisher: American Meteorological Society
Abstract: An experimental simulation of a single-channel, double-angle viewing technique for the determination of sea surface temperature from satellite is presented. This method relies upon the fact that the same area can be viewed ...
Seasonal, Interannual, and Zonal Temperature Variability of the Tropical Stratosphere Based on TOVS Satellite Data: 1987–91
Publisher: American Meteorological Society
Abstract: A 4½-yr monthly stratospheric temperature record derived from TIROS-N Operational Vertical Sounder satellite observations has been used to study the global variability of the stratosphere in the Tropics. A comparison with ...
Multichannel Radiometric Determination of Sea Surface Temperature: Parameterization of the Atmospheric Correction
Publisher: American Meteorological Society
Abstract: Synthetic computations of atmospheric transmissions and radiant energies are presented in order to simulate remote soundings of the sea surface temperature in two pairs of channels: ?8.7 and 11.6 ?m, on the one hand, and ...
Calibration of Geostationary-Satellite Infrared Radiometers Using the TIROS-N Vertical Sounder: Application to METEOSAT-1
Publisher: American Meteorological Society
Abstract: A method is presented for the calibration of infrared radiometers on geostationary satellites using calibrated infrared radiometers on an orbiting satellite. This method relies on similarities between the weighting functions ...
Quantitative Studies of Meteosat Water-Vapor Channel Data
Publisher: American Meteorological Society
Abstract: In this paper, quantitative studies of water vapor Meteosat imagery, based on an accurate transmittance and radiance model are described. Using conventional radiosonde data, a linear relation between cloudless radiances ...

Abstract: First comparisons of improved initialization inversion (3I) cloud parameters determined from TIROS-N Operational Vertical Sounder observations with time?space-collocated clouds from the recently reprocessed International ...
Cloud Field Identification for Earth Radiation Budget Studies. Part I: Cloud Field Classification Using HIRS-MSU Sounder Measurements
Publisher: American Meteorological Society
Abstract: Onboard the NOAA satellites, the High-Resolution Infrared Sounder (HIRS) with its 20 channels, combined with the Microwave Sounding Unit (MSU), provides a powerful tool for cloud field classification at a spatial resolution ...
A Neural Network Approach for a Fast and Accurate Computation of a Longwave Radiative Budget
Publisher: American Meteorological Society
Abstract: The authors have investigated the possibility of elaborating a new generation of radiative transfer models for climate studies based on the neural network technique. The authors show that their neural network?based model, ...
