Download or read book Short Wave Solar Radiation in the Earth s Atmosphere written by Irina N. Melnikova and published by Springer Science & Business Media. This book was released on 2005 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on data from an experiment which ran for ten years, this book summarizes the results of the Atmospheric Physics Department of the St. Petersburg University and the Main Geophysical Observatory. The processed data now forms a rich dataset of spectral values of radiative characteristics under different atmospheric conditions. The analysis of this database clearly shows that the solar radiative absorption in a dusty and cloudy atmosphere is significantly higher than assumed to date. Both graduate students of atmospheric sciences as well as scientists and researchers in the field of meteorology and climatology will find a wealth of new data and information in this monograph.

This book was released on 2003 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le présent manuel rassemble l'essentiel des connaissances actuelles sur le rayonnement solaire. Il s'adresse particulièrement aux étudiants, ingénieurs, médecins, pharmaciens ou biologistes, concernés par les incidences du soleil sur l'environnement et la santé. En première partie, cet ouvrage introduit les diverses grandeurs radiométriques utiles, avec leur application à l'effet de serre. La seconde partie décrit les trajectoires du soleil et les principaux phénomènes causes de l'absorption et de la diffusion de ses rayons par les constituants atmosphériques. La troisième partie présente plusieurs modèles paramétriques du rayonnement solaire, ainsi que les codes de calcul basés sur le transfert radiatif et le lancer aléatoire de photons. La dernière partie, enfin, expose les principes de la mesure des grandeurs solaires et analyse les outils d'évaluation de certaines actions biologiques ou chimiques, telles l'action érythémateuse et la photolyse. De nombreux exercices d'assimilation sont proposés, tous avec un corrigé détaillé.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Treatise on the Sun's Radiation and Other Solar Phenomena: In Continuation of the Meteorological Treatise on Atmospheric Circulation and Radiation, 1915 There are two fundamental problems in solar physics that need an immediate solution: (1) the nature of the solar radiation, whether it is black or gray, that is, whether it has full or imperfect efficiency, together with its amount at the sun, and in the different layers of the earths atmosphere; (2) the physical conditions at which this radiation generates, and the pressures, temperatures, densities, and gas efficiencies that are concerned with the observed phenomena in the solar spectra. It has been found that the system of non-adiabatic meteorology, which was explained in the Author's Treatise on Atmospheric Circulation and Radiation becomes equally applicable in the solar atmospheres by means of a simple transformation. These terms have been computed for several monatomic gases, by the method of trials, and the results are not only instructive in many directions, but they are in complete harmony with the observations made with the spectro-heliograph and the spectro-bolometer. The radiation is black at 5.85 gram calories per square centimeter per minute, when reduced to the equivalent at the distance of the earth; it loses 1.87 calories in the hemispherical non-adiabatic shell of the sun, and is effective on the outside of the earth's atmosphere at 3.98 calories; the course of its depletion is measured by the bolometer to 2.47 calories at the sea level. This conforms with the thermodynamic conditions of the two atmospheres. The pyrheliometer fails to record three important depletions, and it, therefore, cannot account for more than 1.94 calories by the Bouguer formula. The following Treatise is a continuation of the earlier one on Meteorology. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book tude de la correction de la diffusion atmosph rique et du rayonnement solaire r fl chi par la surface agit e de la mer pour l observation de la couleur de l oc an depuis l espace written by François Steinmetz and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La principale difficulté pour l'observation de la "couleur de l'océan" depuis l'espace est d'effectuer les corrections atmosphériques, c'est à dire extraire le signal provenant des océans du signal total largement dominé par la contribution de l'atmosphère. Dans ce cadre, des problèmes spécifiques liés aux capteurs satellitaires utilisés, ou aux conditions d'observations, peuvent apparaître. Dans le cas du capteur POLDER-3, nous avons diagnostiqué des défauts sur les produits marins grâce aux mesures in situ BOUSSOLE, notamment attribuables aux données d'entrée (de niveau 1), et de proposer plusieurs ajustements. Ces modifications ont abouti à une amélioration majeure de précision des produits, d'un facteur 1.5 à 2. De plus, le même algorithme de correction atmosphérique a été appliqué aux données du capteur MERlS, ce qui a permis de mettre en évidence ses propriétés de fonctionnement. Les algorithmes de correction atmosphérique existants sont également limités par la tâche brillante du rayonnement solaire réfléchi par la surface agitée de la mer (le sun glint), ne pouvant fonctionner lorsque ce signal est trop intense. Pour de nombreux capteurs (MERlS, MODIS ... ) ceci rend près de la moitié des observations aux latitudes subtropicales inutilisables. Nous proposons un algorithme, appelé POLYMER, conçu pour fonctionner sur l'ensemble du sun glint. Si le gain en couverture spatiale est spectaculaire, il se fait encore au détriment de la précision des produits. Néanmoins, cet algorithme montre qu'il est possible d'utiliser de données contaminées par le sun glint pour la couleur de l'océan, et ouvre de nouvelles perspective pour les applications futures.
