Related to weather satellite: weather radar

weather satellite,

artificial satellitesatellite, artificial,
object constructed by humans and placed in orbit around the earth or other celestial body (see also space probe). The satellite is lifted from the earth's surface by a rocket and, once placed in orbit, maintains its motion without further rocket propulsion.

 used to gather data on a global basis for improvement of weather forecasting. Information includes cloud cover, storm location, temperature, and heat balance in the earth's atmosphere. The first weather satellites in the United States were those of the Tiros series, which began in 1960; the Nimbus series, which moved in a polar orbit, was next; the Environmental Science Services Administration (ESSA) started in 1966 and launched weather satellites; and in 1972, the Earth Resources Technology Satellite (ERTS) provided photographs to help forecasting. Other meteorological satellites include a series of Geostationary Operational Environmental Satellites (GOES), which send weather data and pictures that cover a section of the United States; China, Japan, India, and the European Space Agency (ESA) have similar craft. The National Oceanic and Atmospheric Administration's satellite series relay meteorological data to stations on the surface, including information on possible changes in various weather parameters that may signal climateclimate,
average condition of the atmosphere near the earth's surface over a long period of time, taking into account temperature, precipitation (see rain), humidity, wind, barometric pressure, and other phenomena.

All other weather satellites operated by the agency as part of a geostationary constellation are healthy and monitoring weather across the nation each day.
More filters, or spectral bands, on the ABI will detect more information about volcanic ash, dust, clouds, winds, fires, rainfall rate, and hurricane intensity than today's geostationary weather satellites. Critical information about severe weather events can come as fast as 30 seconds, five times faster than today.
Queen's University Belfast has been appointed part of a UK group that will build one of the key instruments on Europe's next-generation of weather satellites.
"We have geostationary weather satellites ringing the planet," says Goodman, "but what we need is greater temporal sampling from [higher-resolution] lower-orbiting satellites that pass over a point on Earth much less frequently--two to four times per day--to achieve the needed global coverage." Goodman says the gaps in surface measurements are significant in the developing world--where there is less Earth-based monitoring--compared to European nations and the United States."
At the same time, the GOES-8 weather satellite experienced difficulties.
In the past year alone, more than 13 space shuttle flights were delayed, several attempts to free a stuck antenna on the Galileo space probe failed, and one weather satellite went dead (ironically, on the same day the Mars Observer fell silent).
(A group of Pennsylvania high school students modified a $15 Radio Shack radio antenna for their weather satellite station.) I was skeptical of Holly's antenna, which looked like a big old bird roost.
The 16 GPS satellites, 13,000 miles up, could send signals to a lower-orbit communications or weather satellite, explains Stanford senior research scientist David Hinston.
What I saw at this show were miniature weather stations that are set up in a field and there, through various sensors, monitor the soil moisture, check local weather conditions, communicate with a weather satellite and control irrigation based on all inputs.
The weather satellite will have to wait at least 24 hours to begin its mission for the National Oceanic Atmospheric Administration (NOAA) and NASA after the attempted liftoff from Vandenberg Air Force Base in California today was postponed to Nov.
