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 ...

Atmospheric carbonyl sulfide (OCS) measured remotely by FTIR solar absorption spectrometry [PDF]
Atmospheric Chemistry and Physics, 2018 Atmospheric OCS abundances have been retrieved from infrared spectra measured by the Jet Propulsion Laboratory (JPL) MkIV Fourier transform infra-red (FTIR) spectrometer during 24 balloon flights and during nearly 1100 days of ground-based ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Middle-atmospheric response to a future increase in humidity arising from increased methane abundance [PDF]
, 2004 The response of the middle atmosphere to an increase in humidity arising from a possible future increase in CH4 is examined in a general circulation model with interactive H2O and O3.

Casolba: Balloon Calibration of Solar Cells
E3S Web of Conferences, 2017 In order to make accurate measurements, sun simulators used for solar cell characterisation need to be calibrated with standard solar cells. These so-called secondary working standards are derived from primary reference cells and are used for every cell ...

Low-voltage Power Supply Subsystem for a Sub-Orbital Particle Physic Instrument
Advances in Electrical and Electronic Engineering, 2014 The Japanese Experiment Module–Extreme Universe Space Observatory (JEM-EUSO) is a wide-field (+/-~30°of aperture) 2.5m refractor telescope to be installed in the International Space Station (ISS). The instrument looks downward from its orbit, into Earthâ€

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Stratospheric sulfate aerosol (SSA) is an important part of the Earth's climate system. SSA climate impact is determined in part by particle composition, which has been measured from orbit. The weight percent of sulfuric acid in SSA has been determined from atmospheric infrared transmittance spectra recorded with the Atmospheric Chemistry ...

Three-dimensional model study of the Arctic ozone loss in 2002/2003 and comparison with 1999/2000 and 2003/2004 [PDF]
, 2004 We have used the SLIMCAT 3-D off-line chemical transport model (CTM) to quantify the Arctic chemical ozone loss in the year 2002/2003 and compare it with similar calculations for the winters 1999/2000 and 2003/2004.

A global stratospheric bromine monoxide climatology based on the BASCOE chemical transport model [PDF]
Atmospheric Chemistry and Physics, 2009 A new climatology of stratospheric BrO profiles based on a parameterization using dynamical and chemical indicators has been developed, with the aim to apply it to the retrieval of tropospheric BrO columns from space nadir measurements.
