Tornadoes, nature's most violent and unpredictable storms, descend from the clouds nearly one thousand times yearly and have claimed eighteen thousand American lives since 1880. However, the U.S. Weather Bureau--fearing public panic and believing tornadoes were too fleeting for meteorologists to predict--forbade the use of the word "tornado" in forecasts until 1938. Scanning the Skies traces the history of today's tornado warning system, a unique program that integrates federal, state, and local governments, privately controlled broadcast media, and individuals. Bradford examines the ways in which the tornado warning system has grown from meager beginnings into a program that protects millions of Americans each year. Although no tornado forecasting program existed before WWII, the needs of the military prompted the development of a severe weather warning system in tornado prone areas. Bradford traces the post-war creation of the Air Force centralized tornado forecasting program and its civilian counterpart at the Weather Bureau. Improvements in communication, especially the increasing popularity of television, allowed the Bureau to expand its warning system further. This book highlights the modern tornado watch system and explains how advancements during the latter half of the twentieth-century--such as computerized data collection and processing systems, Doppler radar, state-of-the-art television weather centers, and an extensive public education program--have resulted in the drastic reduction of tornado fatalities.

When the Soviets launched Sputnik in 1957, thousands of ordinary people across the globe seized the opportunity to participate in the start of the Space Age. Known as the "Moonwatchers," these largely forgotten citizen-scientists helped professional astronomers by providing critical and otherwise unavailable information about the first satellites. In Keep Watching the Skies!, Patrick McCray tells the story of this network of pioneers who, fueled by civic pride and exhilarated by space exploration, took part in the twentieth century's biggest scientific endeavor. Around the world, thousands of teenagers, homemakers, teachers, amateur astronomers, and other citizens joined Moonwatch teams. Despite their diverse backgrounds and nationalities, they shared a remarkable faith in the transformative power of science--a faith inspired by the Cold War culture in which they lived. Against the backdrop of the space race and technological advancement, ordinary people developed an unprecedented desire to contribute to scientific knowledge and to investigate their place in the cosmos. Using homemade telescopes and other gadgets, Moonwatchers witnessed firsthand the astonishing beginning of the Space Age. In the process, these amateur scientists organized themselves into a worldwide network of satellite spotters that still exists today. Drawing on previously unexamined letters, photos, scrapbooks, and interviews, Keep Watching the Skies! recreates a pivotal event from a perspective never before examined--that of ordinary people who leaped at a chance to take part in the excitement of space exploration.

The rather specialized field of solar and infrared radiation measurement has become more and more important in the face of growing demands by the renewable energy and climate change research communities for data that are more accurate and have increased temporal and spatial resolution. Updating decades of acquired knowledge in the field, Solar and Infrared Radiation Measurements details the strengths and weaknesses of instruments used to conduct such solar and infrared radiation measurements. Topics covered include: Radiometer design and performance Equipment calibration, installation, operation, and maintenance Data quality assessment Methods to use measured data to estimate irradiance for any surface With a broad range of content that will benefit students and more experienced readers alike, this resource serves as a primer and technical reference that presents the basic terminology and fundamentals for resource assessment. It explores the history of solar radiation instruments and addresses direct normal, global, diffuse, and tilted measurements, as well as the characteristics of instruments used for these measurements. The authors consider methods of assessing the uncertainty of solar measurements and then cover albedo, infrared, net, and spectral irradiance measurements and instrumentation. The book devotes a section to other meteorological instruments, and another to the basics for installing and operating a solar monitoring station. Appendices include information on solar resource assessment modeling and satellite-derived irradiance, along with other useful material. This book’s authors are experts who each have more than 30 years of experience developing and operating multiple measurement stations, working with industry to improve radiometry, and conducting various research projects.

The Syren of the Skies or, Olga Romanoff continues the tale of 'The Brotherhood of Freedom,' a worldwide brotherhood of anarchists fighting the world armed with fantastical airships. They must be quick in accomplishing their goals, as a dangerous comet is heading for the Earth.

Everything's gone wrong. The battleship Timora has crashed into Earth on its arrival, leaving INA stranded on a planet occupied and controlled by mechanized invaders she shouldn't be able to feel with her empathic senses...but she does. Worse, rather than searching for the man she loves, she’s stuck with a vengeful platoon sergeant she hates more than anything in the universe. In this hard-hitting, near-future military science-fiction thriller, the author behind the Better Hero Army name pens an unforgettable new twist on the sixth sense.

In this new pictorial history from Philip Kaplan, the perspectives of both RAF and Luftwaffe airmen are considered within the wider context of one of the most iconic and pivotal conflicts of modern history. ??The Blitz, primarily the bombing of London and the major cities of Britain by the German Air Force, lasted for fifty-seven nights from September 1940 into May 1941. Life under the bombing; the perspectives of German and British airmen; the experience of sheltering in the London Underground; first-hand accounts of the horror by survivors left behind; all these voices are consolidated to great effect, providing a suitable commentary to the rare archive photography on display.??Accounts and photographs of some of the most notable participants caught up in the proceedings include; Al Deere, Geoffrey Page, Brian Kingcome, Peter Townsend, Bob Doe and Ginger Lacey.

The rather specialized field of solar and infrared radiation measurements has become increasingly important due to the increased demands by the renewable energy and climate change research communities for data with higher accuracy and increased temporal and spatial resolutions. Recent advances in radiometry, measurement systems, and information dissemination also have increased the need for refreshing the literature available for this topic. This book provides the reader with an up-to-date review of the important aspects of solar and infrared radiation measurements: radiometer design; equipment installation, operation, maintenance, and calibration; data quality assessment parameters; and the knowledge necessary to properly interpret and apply the measured data to a variety of topics. Each of the authors has more than 40 years of experience with this subject, primarily as the result of developing and operating multiple measurement stations, working with the industry to improve radiometry, and conducting various research projects. The book’s scope and subject matter have been designed to help a wide audience gain a general understanding of this subject and to serve as a technical reference. A student new to the field will benefit from the review of terminology and the historical perspective for radiometry before addressing more detailed topics in radiometry that we hope will be of interest to the more experienced reader. Describes the strengths and weaknesses of irradiance instruments Provides detailed information on how to assess uncertainty in measurements Offers comprehensive background information needed to understand the use of solar instrumentation Discusses design concepts for shadowband radiometers, sky imagers, and satellite-based estimates of solar irradiance at the Earth’s surface Includes chapter-end questions, references, and useful links
