Infrasound direction of arrival determination using a balloon-borne aeroseismometer [PDF]

JASA Express Letters, 2022
Free-floating balloons are an emerging platform for infrasound recording, but they cannot host arrays sufficiently wide for multi-sensor acoustic direction finding techniques.

In situ observations of stratospheric HCl using three-mirror integrated cavity output spectroscopy [PDF]

Atmospheric Measurement Techniques, 2021
Stratospheric HCl observations are an important diagnostic for the evaluation of catalytic processes that impact the ozone layer. We report here in situ balloon-borne observations of HCl employing an off-axis integrated cavity output spectrometer (OA ...

Evidence of horizontal and vertical transport of water in the Southern Hemisphere tropical tropopause layer (TTL) from high-resolution balloon observations [PDF]

Atmospheric Chemistry and Physics, 2016
High-resolution in situ balloon measurements of water vapour, aerosol, methane and temperature in the upper tropical tropopause layer (TTL) and lower stratosphere are used to evaluate the processes affecting the stratospheric water budget: horizontal

Balloon-borne Cosmic Microwave Background experiments [PDF]

EPJ Web of Conferences, 2019
Stratospheric balloon experiments play a unique role in current Cosmic Microwave Background (CMB) studies. CMB research has entered a precision phase, harvesting the detailed properties of its anisotropy, polarization and spectrum, at incredible ...

Intercomparison of in situ water vapor balloon-borne measurements from Pico-SDLA H₂O and FLASH-B in the tropical UTLS [PDF]

Atmospheric Measurement Techniques, 2016
In this paper we compare water vapor mixing ratio measurements from two quasi-parallel flights of the Pico-SDLA H2O and FLASH-B hygrometers. The measurements were made on 10 February 2013 and 13 March 2012, respectively, in the tropics near Bauru, São ...

Aerodynamic Drag Analysis of Superpressure and Zero Pressure Balloons using Large Eddy Simulations (LES) [PDF]

Journal of Applied Fluid Mechanics
Stratospheric balloons are an essential part of the scientific research community. In previous stratospheric balloon models used for trajectory prediction and station-keeping, the aerodynamic drag has usually been modeled as similar to that of a sphere ...
