An observation balloon is a type of balloon that is employed as an aerial platform for gathering intelligence and spotting artillery. The use of observation balloons began during the French Revolutionary Wars , reaching their zenith during World War I , and they continue in limited use today.
The aerostat consists of four major parts or assemblies: the hull and fin, windscreen and radar platform, airborne power generator, and rigging and tether; they are kite balloons obtaining aerodynamic lift from relative wind and buoyancy from being lighter than air.
A weather balloon, also known as a sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments to the stratosphere to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde.
The balloon flying over the U.S. is flying around 60,000 feet over the center of the country, officials said. An observation balloon at Van Cortland Park in New York City during a field artillery ...

[45] The Civil War TV mini-series, The Blue and the Gray, features a scene with Thaddeus Lowe testing his observation balloon during the 1862 Peninsula campaign. Lowe is played by actor ...
A balloon is a form of aerostat, along with the powered free-flying airship, although the American GAO has used the term "aerostat" to describe a tethered balloon in contrast to the powered airship. [1] Tethered balloons have been used for advertising, recreation, observation, and civil or military uses.
The sensor, which is the radiosonde instrument, is powered by a small battery and attached to the balloon; this is what measures the pressure, temperature and relative humidity as it ascends up ...
Earth observation (EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. [1] It can be performed via remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example).
