Lightweight avionics platform to access atmospheric environmental science [PDF]

, 2014
There is a region of the atmosphere between approximately 10-40 km above the Earth’s surface that is inaccessible to most winged aircraft and that rockets visit only fleetingly, but where small unmanned balloons are increasingly being used to carry ...

EnKF and expectation‐maximization based parameter estimation of a convective gravity‐wave parameterization using Strateole 2 constant‐level balloon data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An offline methodology is applied to estimate parameters of a convective gravity‐wave scheme using momentum flux (MF) observations from constant‐level balloons (left panels: pdfs of east and west MFs in green from observations and black from EnKF). The approach integrates an ensemble Kalman filter with an expectation‐maximization algorithm and permits ...

CNR Ozone Sounding Merged (COSM) Dataset From Existing Global Archives

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
The COSM dataset unifies over 101,000 ozonesonde profiles from SHADOZ, NDACC and WOUDC into a harmonized, quality‐controlled archive spanning 1978–2024. It improves global spatial and temporal coverage, supports climate and chemistry studies, and provides a robust resource for satellite validation, model evaluation and trend analysis.

Ozone loss derived from balloon-borne tracer measurements in the 1999/2000 Arctic winter [PDF]

, 2005
Balloon-borne measurements of CFC11 (from the DIRAC in situ gas chromatograph and the DESCARTES grab sampler), ClO and O3 were made during the 1999/2000 Arctic winter as part of the SOLVE-THESEO 2000 campaign, based in Kiruna (Sweden).

Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Telemetry system for research stratospheric balloon [PDF]

2017 International Conference on Applied Electronics (AE), 2017
The paper presents telemetry system for stratospheric balloon mission based on the UHF transceivers designed for Internet of Things. The system operates in 869.5 MHz frequency band. The system uses very short packet without channel coding that can be successfully received and decoded under low signal to noise ratio.
