High Resolution Dynamics Limb Sounder
The high-resolution dynamics limb sounder (HIRDLS) is an instrument on board the NASA Aura. It follows in the heritage of LRIR (Nimbus-6), LIMS and SAMS (Nimbus-7), ISAMS and CLAES (UARS). It was designed to observe global distribution of temperature and concentrations of O3, H2O, CH4, N2O, NO2, HNO3, N2O5, CFC-11, CFC-12, ClONO2, and aerosols in the upper troposphere, stratosphere, and mesosphere. After launch, activation of the HIRDLS instrument revealed that the optical path was blocked so that only 20% of the aperture could view the Earth's atmosphere. Engineering studies suggest that a piece of thermal blanketing material ruptured from the back of the instrument during the explosive decompression of launch. Attempts to remove this material mirror failed. However, even with the 80% blockage, measurements at high vertical resolution can be made at one scan angle.

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Aura (satellite)
Aura (EOS CH-1) is a multi-national NASA scientific research satellite in orbit around the Earth, studying the Earth's ozone layer, air quality and climate. It is the third major component of the Earth Observing System (EOS) following on Terra (launched 1999) and Aqua (launched 2002). Aura follows on from the Upper Atmosphere Research Satellite (UARS). Aura is a joint mission between NASA, the Netherlands, Finland, and the U.K. The Aura spacecraft is healthy and is expected to operate until at least 2022, likely beyond. The name " Aura" comes from the Latin word for air. The satellite was launched from Vandenberg Air Force Base on July 15, 2004, aboard a Delta II 7920-10L rocket. The Aura spacecraft has a mass of about . The body is long with the extended single solar panel about long. Aura flies in a sun-synchronous orbit, in formation with 3 other satellites, collectively known as the " A Train"; it is last in the formation. The other satellites in the formation are: * ...

International Global Atmospheric Chemistry
The International Global Atmospheric Chemistry (IGAC) project is a non-profit organization created in the late 1980s to address growing international concerns over rapid changes observed in Earth's atmosphere. It developed under joint sponsorship of the Commission on Atmospheric Chemistry and Global Pollution ( CACGP) of the International Association of Meteorology and Atmospheric Sciences (IAMAS), and the International Geosphere-Biosphere Programme The International Geosphere-Biosphere Programme (IGBP) was a research programme that ran from 1987 to 2015 dedicated to studying the phenomenon of global change. Its primary focus was coordinating "international research on global-scale and region ... (IGBP). External links More about IGAC Atmospheric chemistry {{environmental-org-stub ...

Microwave Limb Sounder
The microwave limb sounder (MLS) experiments measure (naturally occurring) microwave thermal emission from the limb (edge) of Earth's upper atmosphere. The data is used to create vertical profiles of atmospheric gases, temperature, pressure, and cloud ice. History * 12 September 1991 – NASA launches Upper Atmosphere Research Satellite (UARS) STS-48 mission, largely in response to threat of chlorofluorocarbons to ozone layer. * 15 July 2004 – NASA launches Earth Observing System (EOS) Aura mission with overall scientific objectives of determining whether global stratospheric ozone is recovering, measuring composition effects on climate variability, and studying pollution in the upper troposphere.

Founded in the 1930s by Caltech researchers, JP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
