Balloon ride into the stratosphere

New Scientist, 2007
In 1862 a middle-aged meteorologist travelled in a balloon to an altitude of 11,000 metres and all to report on the ...

The MANTRA campaigns - studying the stratosphere from balloons

IEEE International Geoscience and Remote Sensing Symposium, 2003
The MANTRA (Middle Atmosphere Nitrogen Trend Assessment) series of high-altitude balloon flights is being undertaken to investigate changes in the concentrations of mid-latitude stratospheric ozone, and of nitrogen and chlorine compounds that play a role in ozone chemistry. Two balloons have been launched from Vanscoy, Saskatchewan, the first in August

Balloon-borne remote sensing of stratospheric constituents

Applied Optics, 1983
Data on species of interest in the photochemistry of the ozone layer obtained from balloon flights are presented. The flights made use of remote-sensing instruments that took measurements in the wavelength region from the ultraviolet to millimeter wavelengths.

Schumann resonances observed with a balloon in the stratosphere

Journal of Atmospheric and Terrestrial Physics, 1979
Abstract The electric vertical component of natural ELF noise has been measured with a balloon at two different altitudes, 20 and 26 km in the stratosphere for about 1 day on 3–4 October 1977 over the Pacific Ocean. Observations of high S N -ratio Schumann resonances were detected up to the 7th mode (44.9 Hz) but no higher mode could be ...

Carrier Balloon Trajectories in the Stratosphere

Journal of Applied Meteorology, 1980
Abstract The need for atmospheric sounding data between the surface and 30 mb for the Global Weather Experiment prompted the development of the Carrier Balloon System. During the development period, 23 constant-level balloon flights near 24 km were conducted. The wind trajectories from these flights are described.

Coverage and performance of stratospheric balloons wireless networks

2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016
In this paper we analyze the performance of wireless networks by using stratospheric balloons equipped by base stations (BS). We show that such a solution can be interesting in terms of performance and coverage. Considering a high altitude wireless network, we first establish an analytical expression of the Signal to Interference plus Noise Ratio (SINR)

Software and methodologies for stratospheric balloons

2003
Since the 1999, experts of ISTI (an Institute of the Italian National Research Council) collaborate with ASI (the Italian Space Agency) on the flight dynamic of the Stratospheric Balloons (pre-operation and operation activities included). The latest developments on Subsystems and methodologies for flight prediction will be discussed.

OSAS-B: A Balloon-Borne Terahertz Spectrometer for Atomic Oxygen in the Upper Atmosphere

IEEE Transactions on Terahertz Science and Technology
The oxygen spectrometer for atmospheric science on a balloon (OSAS-B) is the first 4.7-THz heterodyne spectrometer on a stratospheric balloon. It has been developed for remote sensing of the 4.7-THz emission of neutral atomic oxygen in the mesosphere and
