What is meant by meteorological balloon?
a balloon that carries meteorological instruments aloft in order to measure, record and return data concerning atmospheric pressure, temperature and humidity.
What is the definition radiosonde?
: a miniature radio transmitter that is carried aloft (as by an unpiloted balloon) with instruments for sensing and broadcasting atmospheric conditions.
Are radiosondes still used?
Radiosondes provide a primary source of upper-air data and will remain so into the foreseeable future.
How much does a radiosonde cost?
Each individual radiosonde costs about $200. The cost of establishing a radiosonde ground station makes it difficult to increase the spatial extent of the radiosonde network, which is particularly deficient in vast regions of the Southern Hemisphere.
How does a radiosonde work?
The radiosonde is a small, expendable instrument package that is suspended below a six foot wide balloon filled with hydrogen or helium. As the radiosonde rises at about 1,000 feet/minute (300 meters/minute), sensors on the radiosonde measure profiles of pressure, temperature, and relative humidity.
How much does weather balloon cost?
This will vary based on your needs, so we will want to discuss that before we give you an estimate for the entire project. After your initial investment in a StratoStar High-Altitude Weather Balloon Curriculum, the average cost of high-altitude weather balloon equipment is $200-$400.
What happens to a weather balloon at the end of its flight?
A typical weather balloon can last over two hours as it rises into the sky. But what happens when the balloons reach our upper atmosphere? … It expands and explodes because of the lower air pressure at higher altitudes. The time between each frame is 0.02 seconds.
Where do weather balloons go?
They are designed to. After they are launched, they can drift up to 120 miles downwind and up to 100,000 ft. (about 20 miles) into the atmosphere.
