Television Infrared Observation Satellite
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, Signal Corps (United States Army), United States Army S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Polar Operational Environmental Satellites
The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting. The spacecraft were provided by NASA and the European Space Agency (ESA), and NASA's Goddard Space Flight Center oversaw the manufacture, integration and test of the NASA-provided TIROS satellites. The first polar-orbiting weather satellite launched as part of the POES constellation was the Television Infrared Observation Satellite-N ( TIROS-N), which was launched on 13 October 1978. The final spacecraft, NOAA-19 (NOAA-N Prime), was launched on 6 February 2009. The ESA-provided MetOp satellite operated by EUMETSAT utilize POES-heritage instruments for the purpose of data continuity. The Joint Polar Satellite Syste ...

Advanced Microwave Sounding Unit
The advanced microwave sounding unit (AMSU) is a multi-channel microwave radiometer installed on meteorological satellites. The instrument examines several bands of microwave radiation from the atmosphere to perform atmospheric sounding of temperature and moisture levels. Products Level-1 radiance data are calibrated brightness temperatures. Level-2 geophysical data from AMSU include: * Temperature profile from 3 Bar (unit), mbar (45 km) to the surface * Water vapor profiles * Snow and ice coverage * Cloud liquid water * Rain Rate AMSU data is also used together with infrared radiances from HIRS, AIRS, or IASI to produce blended MW/IR level-2 geophysical products such as: * Temperature profiles * Water vapor profiles * Ozone * Cloud properties * Cloud-cleared IR radiances Applications AMSU data is used extensively in weather prediction. Brightness temperatures are processed as quickly as possible and sent to numerical weather prediction (NWP) centers around the world. ...

Advanced Very-high-resolution Radiometer
The Advanced Very-High-Resolution Radiometer (AVHRR) instrument is a space-borne sensor that measures the reflectance of the Earth in five spectral bands that are relatively wide by today's standards. AVHRR instruments are or have been carried by the National Oceanic and Atmospheric Administration (NOAA) family of polar orbiting platforms ( POES) and European MetOp satellites. The instrument scans several channels; two are centered on the red (0.6 micrometres) and near-infrared (0.9 micrometres) regions, a third one is located around 3.5 micrometres, and another two the thermal radiation emitted by the planet, around 11 and 12 micrometres. The first AVHRR instrument was a four-channel radiometer. The final version, AVHRR/3, first carried on NOAA-15 launched in May 1998, acquires data in six channels. The AVHRR has been succeeded by the Visible Infrared Imaging Radiometer Suite, carried on the Joint Polar Satellite System spacecraft. Operation NOAA has at le ...
