Heavy hydrogen in the stratosphere [PDF]

open access: yes, 2003
We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40º N in October 2002. Strong deuterium enrichments of up to

The stratospheric quasi-biennial oscillation observed in the semidiurnal ground pressure data [PDF]

open access: yesAnnales Geophysicae, 1995
Ground pressure observations made at Macao (22°N, 113°E) from 1953 to 1991 are analyzed and compared with the stratospheric quasi-biennial oscillation (QBO) data obtained during the same interval.

Observations of meteoric material and implications for aerosol nucleation in the winter Arctic lower stratosphere derived from in situ particle measurements [PDF]

open access: yes, 2005
Number concentrations of total and non-volatile aerosol particles with size diameters >0.01 μm as well as particle size distributions (0.4–23 μm diameter) were measured in situ in the Arctic lower stratosphere (10–20.5 km altitude). The measurements were

Seasonal and annual variations of aerosol concentrations in the troposphere and stratosphere over Syowa Station observed by a balloon-borne optical particle counter

open access: yesAntarctic Record, 2010
This report summarizes observations of tropospheric and stratospheric aerosols by a balloon-borne optical particle counter (Aerosol sonde) performed at Syowa Station from April 1997 to January 2008.

Evaluation of Antarctic Ozone Profiles derived from OMPS-LP by using Balloon-borne Ozonesondes

open access: yesScientific Reports, 2021
Predicting radiative forcing due to Antarctic stratospheric ozone recovery requires detecting changes in the ozone vertical distribution. In this endeavor, the Limb Profiler of the Ozone Mapping and Profiler Suite (OMPS-LP), aboard the Suomi NPP ...

Chemical ozone loss in the Arctic winter 1991–1992 [PDF]

open access: yes, 2007
Chemical ozone loss in winter 1991–1992 is recalculated based on observations of the HALOE satellite instrument, Version 19, ER-2 aircraft measurements and balloon data.

Acoustic Waves From a Distant Explosion Recorded on a Continuously Ascending Balloon in the Middle Stratosphere

open access: yesGeophysical Research Letters, 2023
A helium‐filled mylar balloon carrying a smartphone and infrasound sensors ascended to a stratospheric height of 35 km over the surface detonation of a chemical explosive, with a total acoustic propagation distance of 127 km.

Validation of MIPAS-ENVISAT H2O operational data collected between July 2002 and March 2004 [PDF]

open access: yes, 2013
Water vapour (H2O) is one of the operationally retrieved key species of the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) instrument aboard the Environmental Satellite (ENVISAT) which was launched into its sun-synchronous orbit on 1 ...

EUSO-BALLOON a pathfinder for detecting UHECR's from the edge of space

open access: yesEPJ Web of Conferences, 2013
EUSO-Balloon has been conceived as a pathfinder mission for JEM-EUSO, to perform an end-to-end test of the subsystems and components, and to prove the global detection chain while improving our knowledge of the atmospheric and terrestrial UV background ...
