Download or read book The Atmosphere and Climate of Mars written by Robert M. Haberle and published by Cambridge University Press. This book was released on 2017-06-29 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s. These orbiters, landers and rovers have generated vast amounts of data that now span a Martian decade (roughly eighteen years). This new volume brings together the many new ideas about the atmosphere and climate system that have emerged, including the complex interplay of the volatile and dust cycles, the atmosphere-surface interactions that connect them over time, and the diversity of the planet's environment and its complex history. Including tutorials and explanations of complicated ideas, students, researchers and non-specialists alike are able to use this resource to gain a thorough and up-to-date understanding of this most Earth-like of planetary neighbours.

Download or read book Structure and Composition Measurements in Equatorial Ionospheric Bubbles written by R. Narcisi and published by . This book was released on 1980 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two multi-instrumented Terrier Malemute rockets including ion mass spectrometers were launched from Kwajalein on the nights of 17 and 23 July 1979 during equatorial Spread F events. Detailed ionospheric structure and composition measurements were made between about 100 and 590 km. The first flight penetrated six areas of 'bite-outs' spread over the range 265 to 560 km on upleg as well as several more depletions on downleg. The strongest irregularities, up to 90 percent depletion, occurred at the altitudes of 265 to 285 km just above the F region ledge at 250 km. There was no evidence of enhanced bottomside tracer ions (NO(+), O2(+) or meteoric ions) in any of the holes, which were composed mostly of O(+) and smaller amounts of N(+). From the composition signatures, the source of the bubbles appeared to be near the F region ledge. Within the higher altitude holes, the N(+)/O(+) ratios were smaller than the adjacent ionosphere ratios, indicating not only that the source regions were near the ledge, but also that the bubbles had initiated earlier when the ledge was at higher altitudes. While O(+) and N(+) exhibited strong fluctuations, NO(+) and O2(+) had fairly smooth profiles with scale heights similar to N2 and O2 respectively, demonstrating steady-state conditions and a stable neutral atmosphere with an exospheric temperature of about 1100K. This suggests that neutral atmospheric turbulence is not a major source of the ionospheric irregularities. Time periods for ion-chemical processes to achieve the observed composition are discussed in terms of bubble formation times and rise velocities.

Download or read book Atmospheric Boundary Layer Flows written by J. C. Kaimal and published by Oxford University Press. This book was released on 1994-01-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boundary layer meteorology is the study of the physical processes that take place in the layer of air that is most influenced by the earth's underlying surface. This text/reference gives an uncomplicated view of the structure of the boundary layer, the instruments available for measuring its mean and turbulent properties, how best to make the measurements, and ways to process and analyze the data. The main applications of the book are in atmospheric modelling, wind engineering, air pollution, and agricultural meteorology. The authors have pioneered research on atmospheric turbulence and flow, and are noted for their contributions to the study of the boundary layer. This important work will interest atmospheric scientists, meteorologists, and students and faculty in these fields.

Download or read book Neutral Composition Measurements of the Mesosphere and Lower Thermosphere written by Charles R. Philbrick and published by . This book was released on 1971 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recently developed rocket-borne mass spectrometer which employs a LN2 cryosorption pump has successfully obtained the first direct measurements of the major and minor neutral constituents of the mesosphere and lower thermosphere. The mass analysis is performed using an rf quadrupole spectrometer with an electron impact ion source. Measurements were obtained from two flights, and the preliminary results from one of these are presented. The constituents measured include N2, O2, Ar, O, CO2, O3, and several other minor constituents. Measurements were obtained from 70 to 120 km. Atomic oxygen measurements were obtained between 85 km and apogee on both up-leg and down-leg of the flight. The atomic oxygen measurements were obtained at lower altitudes by switching the ion source potentials on alternate spectral scans to ionize with 20-eV electrons. The lower ionizing energy reduces that portion of the signal at 16 amu due to dissociative ionization of O2. Number density profiles of individual constituents were obtained by normalizing the relative abundances to a density model. (Author).

Download or read book COSPAR: Space Research written by M. J. Rycroft and published by Elsevier. This book was released on 2013-10-22 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cospar Space Research, Volume XIX covers the proceedings of the Open Meetings of the Working Groups on Physical Sciences of the 21st Plenary Meeting of COSPAR, held in Innsbruck, Austria, from May 29 to June 10, 1978, focusing on the developments in space research. The contributions concentrate on remote sensing, middle atmosphere, ionosphere, magnetosphere, and materials science in space. The selection first offers information on global development of space research, including weather and climate, material sciences in space, planets, sun, stars, magnetosphere, and high energy astrophysics. The book then takes a look at the spectral characteristics of surface phenomena and their impact on the design of an optoelectronic multispectral system; use of weather satellite data in the evaluation of water resources; and atmospheric and surface radiation balance as identified from satellite data. The compilation discusses the assimilation of non-simultaneous satellite and conventional meteorological data using statistical weights; annual variation and variability of meteorological parameters in the stratosphere and mesosphere; and physical properties affecting the existence of small particles in the mesosphere. The book also focuses on the determination of density scale-height profiles, geomagnetic effects in the exosphere, and gravity waves and tidal winds in the equatorial thermosphere. The selection is a dependable source of data for readers interested in space research.

Download or read book Spacecraft that Explored the Inner Planets Venus and Mercury written by Thomas Lund and published by Springer Nature. This book was released on 2023-07-03 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of increasingly capable spacecraft were sent to explore the inner planets Venus and Mercury. The history of that planetary exploration is traced in this book along with the evolution of sophisticated spacecraft that unveiled long-sought secrets of the planets. The spacecraft were ingenious and reflected the best efforts of talented people working with the available technology of the day. Additionally, this book showcases engineering involved in those capable machines. A consecutive series of 34 planetary spacecraft, which span the time period 1961 to 2021, are described. This includes the unsuccessful missions of several early spacecraft that paved the way for a better understanding of Venus’ hostile environments. This book will describe many successful spacecraft sent to Venus by the Soviet Union and many successful spacecraft sent to Venus and to Mercury by the United States. The recent exploration of Venus by the European Space Agency’s Venus Express and the Japanese spacecraft Akatsuki can also be found in this book. The author draws on over 50 years of experience on aircraft and spacecraft systems to tell the story of these planetary spacecraft. The spacecraft experience includes being the technical lead for the landing radars on the Surveyor and Apollo lunar landers as well as providing analyses for the rendezvous radar for the Space Shuttle. Practical engineering experience is augmented by Master’s degrees in electrical engineering, physics, and business administration.
