TIROS
Television InfraRed Observation Satellite (TIROS) is a series of early weather satellites launched by the United States, beginning with TIROS-1 in 1960. TIROS was the first satellite that was capable of remote sensing of the Earth, enabling scientists to view the Earth from a new perspective: space. The program, promoted by Harry Wexler, proved the usefulness of satellite weather observation, at a time when military reconnaissance satellites were secretly in development or use. TIROS demonstrated at that time that "the key to genius is often simplicity". TIROS is an acronym of "Television InfraRed Observation Satellite" and is also the plural of "tiro" which means "a young soldier, a beginner". The Advanced Research Projects Agency (now DARPA) initiated the TIROS program in 1958 and transferred the program to the National Aeronautics and Space Administration (NASA) in 1959. Participants in the TIROS program also included, United States Army Signal Research and Development Lab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TIROS-1
TIROS-1 (or TIROS-A) was the first operational weather satellite, the first of a series of ''Television Infrared Observation Satellites'' (TIROS) placed in low Earth orbit. Program The TIROS Program was NASA's first experimental step to determine if satellites could be useful in the study of the Earth. At that time, the effectiveness of satellite observations was still unproven. Since satellites were a new technology, the TIROS Program also tested various design issues for spacecraft: instruments, data and operational parameters. The goal was to improve satellite applications for Earth-bound decisions, such as "should we evacuate the coast because of the hurricane?". The TIROS-1 Program's first priority was the development of a Meteorology, meteorological satellite information system. Weather forecasting was deemed the most promising application of space-based observations. Spacecraft TIROS 1 was an 18-sided right Prism (geometry), prism, across opposite corners and hig ...

Weather Satellite
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites are mainly of two types: polar orbiting (covering the entire Earth asynchronously) or geostationary (hovering over the same spot on the equator). While primarily used to detect the development and movement of storm systems and other cloud patterns, meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, and energy flows. Other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El Niño and its effects on wea ...

Harry Wexler
Harry Wexler (March 15, 1911 – August 11, 1962) was an American meteorologist, born in Fall River, Massachusetts. Biography Wexler attended Harvard University, and in 1939 he was awarded a Ph.D. in meteorology under Carl-Gustaf Rossby from the Massachusetts Institute of Technology. He worked for the United States Weather Bureau from 1934 until 1942, then served as a Captain to a Lieutenant Colonel with the weather service of the Army Air Corps during World War II from 1942 until 1946. On September 14, 1944, Major Harry Wexler became the first scientist to deliberately fly into a hurricane. He accompanied a flight of a Douglas A-20 "Havoc" that flew into the hurricane to collect scientific data. In 1946 he returned to the U.S. Weather Bureau, becoming Chief of the Scientific Services division. As head researcher, Wexler encouraged a study into the atmospheres of planets other than the Earth. He is particularly noted for his work on the use of satellites for meteorological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meteorology
Meteorology is the scientific study of the Earth's atmosphere and short-term atmospheric phenomena (i.e. weather), with a focus on weather forecasting. It has applications in the military, aviation, energy production, transport, agriculture, construction, weather warnings and disaster management. Along with climatology, atmospheric physics and atmospheric chemistry, meteorology forms the broader field of the atmospheric sciences. The interactions between Earth's atmosphere and its oceans (notably El Niño and La Niña) are studied in the interdisciplinary field of hydrometeorology. Other interdisciplinary areas include biometeorology, space weather and planetary meteorology. Marine weather forecasting relates meteorology to maritime and coastal safety, based on atmospheric interactions with large bodies of water. Meteorologists study meteorological phenomena driven by solar radiation, Earth's rotation, ocean currents and other factors. These include everyday ...

Outgoing Longwave Radiation
In climate science, longwave radiation (LWR) is electromagnetic radiation, electromagnetic thermal radiation emitted by Earth's surface, atmosphere, and clouds. It is also referred to as terrestrial radiation. This radiation is in the infrared portion of the spectrum, but is distinct from the shortwave radiation, shortwave (SW) near-infrared radiation found in sunlight. Outgoing longwave radiation (OLR) is the longwave radiation emitted to space from the top of Earth's atmosphere. It may also be referred to as ''emitted terrestrial radiation''. Outgoing longwave radiation plays an important role in planetary cooling. Longwave radiation generally spans wavelengths ranging from 3–100 micrometres (μm). A cutoff of 4 μm is sometimes used to differentiate sunlight from longwave radiation. Less than 1% of sunlight has wavelengths greater than 4 μm. Over 99% of outgoing longwave radiation has wavelengths between 4 μm and 100 μm. The Radiative flux, flux of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Camera
A professional video camera (often called a television camera even though its use has spread beyond television) is a high-end device for creating electronic moving images (as opposed to a movie camera, that earlier recorded the images on filmstock, film). Originally developed for use in television studios or with Outside broadcasting, outside broadcast Production truck, trucks, they are now also used for music videos, direct-to-video movies (see digital movie camera), corporate and educational videos, wedding videos, among other uses. Since the 2000s, most professional video cameras are digital (instead of analog). The distinction between professional video cameras and movie cameras narrowed as HD digital video cameras with sensors the same size as 35mm movie cameras - plus Dynamic range#Photography, dynamic range (exposure latitude) and color rendition approaching film quality - were introduced in the late 2010s. Nowadays, HDTV cameras designed for broadcast television, news, sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Advisory Committee For Aeronautics
The National Advisory Committee for Aeronautics (NACA) was a United States federal agency that was founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved and its assets and personnel were transferred to the newly created National Aeronautics and Space Administration (NASA). NACA is an initialism, pronounced as individual letters rather than as a whole word, as was NASA during the early years after being established. Among other advancements, NACA research and development produced the NACA duct, a type of air intake used in modern automotive applications, the NACA cowling, and several series of NACA airfoils, which are still used in aircraft manufacturing. During World War II, NACA was described as "The Force Behind Our Air Supremacy" due to its key role in producing working superchargers for high altitude bombers, and for producing the laminar wing profiles for the North American P-51 Mustan ...
