Unraveling atmospheric physics and chemistry of long-range transport of pollutants: Development of novel tools and methods
… of PM2.5. In the third chapter, we introduced a physics-based convective mixing scheme and explored the impact of implementing this scheme in CMAQ on the LRT of pollutants. Results revealed the potential of the new scheme to substantially increase or decrease CO concentrations at different …

Trace gas imaging in the atmosphere with a Fabry-Pérot interferometer - a case study for sulfur dioxide
Atmospheric trace gas imaging allows the direct assessment of chemical dynamics, transport and mixing processes and is therefore desired in atmospheric physics and chemistry. For instance, the application of imaging measurements at trace gas point sources can substantially improve the determination …

High resolution Doppler spectroscopy of a transiting ultra-hot Jupiter at optical wavelengths
… are fascinating laboratories for extreme atmospheric physics, and their size, translucent atmospheres and proximity to their host stars makes them excellent targets for characterisation through transmission spectroscopy. Recently, ultra-hot Jupiters (UHJs) have emerged as a distinct class …

Multi-Scale Studies to Develop a Holistic Understanding of Solid Fuel Combustion at Residential Scale
… primary aerosols, which play important roles in atmospheric physics and chemistry, and affects regional and global climate with a net warming effect. To curb the adverse impacts of HAP, the United Nations has set a Sustainable Development Goal of eradicating energy poverty by 2030.</p><p>Research …

Thermal and Radiative Properties of Exoplanet Atmospheres Across the Mass Range
… investigating important considerations for the atmospheric retrieval of isolated brown dwarfs. These objects provide remarkable laboratories for understanding atmospheric physics in the low-irradiation regime, and can be observed more precisely than exoplanets. As such, they provide a glimpse …

Development of ground and space based instrumentation for middle and upper atmospheric studies
… with this system is to obtain measurements of atmospheric tides, planetary and gravity wave amplitudes and phase in the lower thermosphere. Measurement of waves into the lower thermosphere is accomplished using Rayleigh lidar methods with high power-aperture (PA) products using new technology …

Recovering the hydrocarbon distributions in Saturn's upper atmosphere through mathematical inversion.
The spacecraft Voyager 2 UVS occultation experiments measured the ultraviolet absorption properties of the upper atmosphere of Saturn. In the extreme-ultraviolet wavelength region from 1300 Å to 1700 Å, CH₄, C₂H₂, C₂H₄, C₂H₆ and C₄H₂ are the major absorbers in the Saturnian upper atmosphere. In …

Optical studies of the mesospheric region
A three-field photometer has been employed at the University of Adelaide's Buckland Park field site to collect optical observations of the 557.7nm OI and 730nm OH airglow emissions. Data have been collected on an almost continuous basis since May 1995 through to May 2000, with observations made …

Contaminated Sweeping Langmuir Probes on Sounding Rocket Platforms
… simulations and in-situ data from the APEP (Atmospheric Perturbations around Eclipse Path) sounding rocket mission demonstrate the impacts of voltage sweep profiles on contaminated probes. These design considerations made prior to launch can have irreversible and detrimental effects on the …

Instrument and Influence: The Problem of Fair Weather Electricity (1850–1930)
… a history of the fair weather problem, an atmospheric electric phenomenon, between 1850 and 1930. The analogy and presumed identity between lightning and the sparks drawn from electrical machines in 1752 has been heralded as a pivotal moment in the history of physics. That same year, …

Visualising the Aurora: Embodied and Instrumental Sensing throughout the International Polar and Geophysical Years (1880-1960)
… a transient, unpredictable and intangible atmospheric object. Photography, spectroscopy, radio imaging and the introduction of the all-sky perspective were integral technological developments, influencing the ways in which the aurora was presented and viewed. Nevertheless, experiential …
