This book was released on 1973 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a description and detailed analysis of a technique for inferring atmospheric ozone information from satellite nadir measurements in the 1042 cm−1 band. A method is formulated for computing the emission from the lower boundary under the satellite which circumvents the difficult analytical problems caused by the presence of atmospheric clouds and the water-vapor continuum absorption. The inversion equations are expanded in terms of the eigenvectors and eigenvalues of a least-squares-solution matrix, and an analysis is performed to determine the information content of the radiance measurements. The results show that under favorable conditions there are only two pieces of independent information available from the measurements: the total ozone u and the altitude hm of the primary maximum in the ozone profile. An error analysis shows that errors in u are affected most by random radiance noise, lower boundary temperature errors, and ozone absorption-line intensity errors. Errors in hm are affected most by the former two errors and also by temperature-profile bias errors. The results when all errors are considered simultaneously indicate that it should ultimately be possible to determine u to within 10 percent or less and to determine hm to within 1.5 km when the root-mean-square radiance noise level is 1 percent or less. The calculations are also made for various degrees of cloudiness in the troposphere. The data show that the presence of clouds does not seriously affect results as long as there is some contrast between the ozone spectrum and the lower boundary emission spectrum. Finally, the inversion technique is applied to radiances measured from a balloon over Palestine, Texas, and to Nimbus III satellite data measured over the Bahama Islands.

Available in PDF, EPUB and Kindle. Book excerpt: An increasing allllo~/allce because of the anthropogenically induced ozone depletion and relevant illcrca5e of the surface ultraviolet (UV) radiation (including erythemal part of the UV spectrum) has resulted in the growth of interest to total ozone (TOZ) surface and satellite observations, surface UV measurements (with an emphasis on UV -B) and. the interpretation of observation results to assess potential impacts of the UV radiation enhancement on man and biosphere. The significance of this phenomenon is diJIcrent in various cowltries. Special attention has been paid, for instance, to ozone depletion and UV radiation increase at high latitudes (this problem has also been discussed during the Workshop). It is equally clear, however, that low and mid-latitude environmental dynamics requires carefuU monitoring and assessment of environm(:ntal trends as well. Such a conclusion is especially true for the Mediterranean Region where numerous resort places are located and subject to excessive levels of Solar Ultraviolet Radiation. This is why the NATO Advanced Rcsearch Workshop "Ground-Level and Satellite Ozone Observations: Changes in the Mediterranean Region" was organized and took place in Athens (Grcccc) during the Lime period 31 October -4 November 1995. It should be pointed out, however, that presentations discussed during the Workshop went far beyond the regional scale of consideration. This has been very important, because it opened an opportwlity to analyse the Mediterrane:an environmental situation in the broader contcx1 of the European global changes.

Book Remote Sensing and Atmospheric Ozone

Download or read book Remote Sensing and Atmospheric Ozone written by Arthur Philip Cracknell and published by Springer Science & Business Media. This book was released on 2012-06-21 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: The destruction of the ozone layer, together with global warming, is one of the hot environmental topics of today. This book examines the effect of human activities on atmospheric ozone, namely the increase of tropospheric ozone and the general diminution of stratospheric ozone and the production of the Antarctic ozone hole. Also discussed is the role of remote sensing techniques in the understanding of the effects of human activities on atmospheric ozone as well as in the development of social and political awareness of the damage to the ozone layer by man-made chemicals, principally CFCs. This led to the formulation and ratification in 1989 of the Montreal Protocol on controlling/banning the manufacture and use of chemicals that damage the ozone layer. Since then, remote sensing has played a key role in monitoring atmospheric ozone concentration and determining the success of the Montreal Protocol in protecting the ozone layer from further damage. In this book, the renowned authors discuss the sophisticated instruments that have been launched into space to study not only ozone but also other trace gases in the atmosphere, some of which play a key role in the generation and destruction of ozone in the atmosphere. Professors Cracknell and Varotsos also examine the satellite-flown instruments which are involved in monitoring the absorption of solar ultraviolet light in the atmosphere in relation both to the generation and destruction of ozone and consequently to human health. This scholarly book, written by the foremost experts in the field, looks at remote sensing and its employment in the various aspects of ozone science. It is widely acknowledged that global warming, due to anthropogenic greenhouse gases emissions, represents a threat to the sustainability of human life on Earth. However, many other threats are potentially just as serious, including atmospheric pollution, ozone depletion, water pollution, the degradation of agricultural land, deforestation, the depletion of the world's mineral resources and population growth.

Book Study of Atmospheric Ozone Variations from Surface and Satellite Data

Download or read book Study of Atmospheric Ozone Variations from Surface and Satellite Data written by Hatem Hussny Hassan and published by LAP Lambert Academic Publishing. This book was released on 2011-12 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: As it is more or less agreed that atmospheric ozone is created by the action of sunlight on Oxygen, it might reasonably by expected that the Ozone amount would be at maximum in Summer and at a minimum in Winter. Observations show that this is not the case, But theories suggest a maximum Ozone in quantity in Summer (June) and a minimum in Winter (December) in N-hemisphere whilst in reality the maximum in high N-latitudes is about March and the minimum about October. The discrepancy between theory and observation is most probably due to meteorological processes. One of the most important minor constituents of air is triatomic Oxygen (O3). Ozone has been existed in the atmosphere. Results had demonstrated and suggested that the absence of the part of the sun's spectra in the Ultra-Violet band be due to absorption by atmospheric Ozone. There are many kinds of measurements and observations of the total amount of Ozone. The measurements come from the ground-based instruments (DOBSON and BREWER Spectrometer) during scientific missions and TOMS (Total Ozone Mapping Spectrometer) Satellite.
