Atmospheric interventions
… is important for these environments to have an atmospheric affect that is absorbed through the senses. Architecture is then seen as a stimulus by provoking and challenging the body and creating a consciousness of body and environment. This thesis states that the sensorial appreciation in …

Terahertz wireless communication through atmospheric atmospheric turbulence and rain
… is mainly studied under propagation through atmospheric turbulence and rain. However, as real outdoor weather conditions are temporally and spatially varying, it is difficult to obtain reproducible atmospheric conditions to verify results of independent measurements making it a challenge to …

Atmospheric Deposition Monitoring to Assess Trends in Atmospheric Species
*This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation). The CD requires the following system requirements: Microsoft Office.

Atmospheric microplastic pollution
… the beginning of the new field of research on theatmospheric transport of microplastic and its potential terrestrial and oceanicsource. Taking atmospheric deposition samples from the French Pyrenees Iwas able to illustrate the first atmospheric transport of microplastics of at least95km using …

Investigating the pH of atmospheric fine particles and implications for atmospheric chemistry
Particle acidity is a critical but poorly understood quantity that affects many aerosol processes and properties, including aerosol composition and toxicity. In this study, particle pH and water (which affects pH) are predicted using a thermodynamic model and measurements of RH, T, and inorganic …

Measurements of Atmospheric Radicals
<p>Atmospheric particulate matter (PM) is a global health concern. PM<sub>2.5</sub> is formed primarily through combustion processes such as automobile use and industrial activity. Natural sources of PM<sub>2.5</sub> result from events like volcanos and wildfires. Upon inhalation, PM<sub>2.5</sub> …

Atmospheric organic aerosol - water interactions
Atmospheric aerosols are responsible for adverse health effects and uncertain climate forcing. Depending on their composition, they can directly affect climate by scattering or absorbing solar radiation and they can also indirectly affect by serving as cloud condensation nuclei (CCN). While the …

Infrasound as upper atmospheric monitor
… of the upper atmosphere. Depending on the atmospheric conditions, stratospheric, mesospheric and thermospheric arrivals are observed during intervals of explosive volcanic activity. It is found that the travel times and dominant frequencies of the thermospheric arrivals exhibit a coherent …

Surfactant Behavior in Atmospheric Aerosols
Atmospheric aerosols are very important in the Earth climate system due to their role in cloud formation and the global radiation budget. However, there are still many unanswered questions about how the composition of the aerosol varies and how this composition affects the climate system. While …

Warm and cold atmospheric frontogenesis
Various differences and similarities of warm and cold frontogenesis are numerically modeled. The hydrostatic, adiabatic, Boussinesq primitive equations are integrated on a two dimensional grid. The frontogenesis is forced by an a1ong·front gradient of potential temperature and by a vertically …

Multiple frequency atmospheric radar techniques
… of pulsed-Doppler very high frequency (VHF) atmospheric radars, especially with regards to the two-frequency technique known as frequency domain interferometry (FDI). This technique consists of transmitting alternate pulses on two distinct carrier frequencies. The two resulting time series …

Fluctuating concentrations in atmospheric dispersion
… concentration measurements from a series of atmospheric dispersion experiments conducted under both unstable and stable meteorological conditions. The experiments were undertaken at two different sites, over both flat and gently rolling terrain. Two types of surface-level point aerosol …

Evolution of atmospheric baroclinic waves
The evolution of atmospheric baroclinic waves is investigated by a six-layer forced dissipative quasi-geostrophic $\beta$-plane channel model. In the control run, the model has: (i) a realistic zonal thermal forcing, (ii) a surface Ekman layer, a Newtonian cooling and an interior biharmonic …

Precursors to atmospheric blocking events
Atmospheric blocking disturbs synoptic-scale features from their normal eastward progression, causing extreme weather conditions for the duration of the blocking event. Blocking precursors, as indicators of meridional flow preceding the onset of strong Atlantic blocking episodes, have been …

Precursors to atmospheric blocking events
Atmospheric blocking events disturb synoptic-scale features from their normal eastward progression, causing anomalous weather conditions for the duration of the blocking event. The essence of blocking can be captured by variation of potential temperature ([theta]trop) on the dynamically-defined …
