Optical Emissions Generated During Ionospheric Heating, Charles Kiumo Mutiso Jun 2008

Optical Emissions Generated During Ionospheric Heating, Charles Kiumo Mutiso

Master's Theses - Daytona Beach

Ionospheric heating, accomplished by transmitting a high-frequency electromagnetic wave into the atmosphere, stimulates a large number of linear and non-linear wave-plasma interactions. One outcome of these interactions is the acceleration of thermal ionospheric electrons, leading to the production of induced optical emissions. Detection of these emissions yields information regarding wave-plasma interactions, which are of fundamental importance in many physical processes, and provides an effective means of remotely sensing ionospheric constituents and dynamics.

During an ionospheric heating experiment performed at the High Power Auroral Stimulation facility in Alaska (64.9° N, 146.8° W), a modified Czerny-Turner grating spectrometer acquired high resolution optical …

Local Anthropogenic Impact On Particulate Elemental Carbon Concentrations At Summit, Greenland, Gayle S.W. Hagler, M Bergin, E A. Smith, M Town, Jack E. Dibb May 2008

Local Anthropogenic Impact On Particulate Elemental Carbon Concentrations At Summit, Greenland, Gayle S.W. Hagler, M Bergin, E A. Smith, M Town, Jack E. Dibb

Earth Sciences

Summit, Greenland is a remote Arctic research station allowing for field measurements at the highest point of the Greenland Ice Sheet. Due to the current reliance on diesel generators for electricity at Summit, unavoidable local emissions are a potential contamination threat to the measurement of combustion-related species in the air and snow. The effect of fossil-fuel combustion on particulate elemental carbon (EC) is assessed by a combination of ambient measurements (∼1 km from the main camp), a series of snow pits, and Gaussian plume modeling. Ambient measurements indicate that the air directly downwind of the research station generators experiences particulate …

Hazard Adaptations Along The Ohio River: A Case Study Of Bushman's Lake, Clark County, Indiana, Jennifer L. Lathem

All-Inclusive List of Electronic Theses and Dissertations

Hazard researchers define a hazard as a threat to people and their belongings (Cutter 2001). An adaptation, for the purposes of this research, is any alteration, physical or behavioral, made by a person in which the person is better able to survive in their "hazardous" natural environment. The challenge facing individuals and communities is the ability to adapt to these hazards so as to continue with normal everyday life. People living near a waterway are faced with flooding, which becomes a hazard when it alters everyday social structures. The purpose of this study is to identify flood hazard adaptations in …

Algorithm Development For Column Water Vapor Retrieval Using The Sun And Aureole Measurement (Sam) Sensor, Joshua Bruce Williams May 2008

Algorithm Development For Column Water Vapor Retrieval Using The Sun And Aureole Measurement (Sam) Sensor, Joshua Bruce Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To understand and model the energetics of the Sun-Earth connection, measurements of specific atmospheric molecules are beneficial. The objective is to formulate an algorithm to derive temporally varying atmospheric water vapor concentrations as functions of altitude, latitude, and longitude from solar irradiance absorption measurements. The Visidyne SAM (Sun and Aureole Measurement) instrument, which studies the size and distribution of cloud particles, was used to obtain the experimental data. By introducing a spectrometer to the SAM instrument, column water vapor is produced as part of the data product. A new model optimized algorithm is developed and tested versus existing algorithms. Through …

The Impact Of Local Sources And Long-Range Transport On Aerosol Properties Over The Northeast U.S. Region During Intex-Na, K L. Thornhill, Gao Chen, Jack E. Dibb, C. Jordan, Ali Omar, E L. Winstead, Greg Schuster, A D. Clarke, Cameron Mcnaughton, Eric Scheuer, D R. Blake, Glen Sachse, L Gregory Huey, H B. Singh, Bruce E. Anderson

Earth Sciences

We use data collected aboard the NASA DC-8 aircraft during the summer 2004, Intercontinental Transport and Chemical Evolution Experiment over North America (INTEX-NA) field campaign to examine the origin, composition, physical and optical properties of aerosols within air masses sampled over and downwind of the northeastern U.S. We note that aerosol concentrations within the region exhibited steep vertical gradients and significant variability in both time and space. An examination of air mass chemical signatures and backward trajectories indicates that transport from four, significantly different source regions contributed to the variability: the subtropical Atlantic Ocean (AO); the U.S. west coast and …

Earth Sciences

Gas-phase elemental mercury (Hg°) was measured aboard the NASA DC-8 aircraft during the Intercontinental Chemical Transport Experiment Phase B (INTEX-B) campaign in spring 2006. Flights were conducted around Mexico City and on two subsequent deployments over the North Pacific based out of Honolulu, Hawaii and Anchorage, Alaska. Data obtained from 0.15–12 km altitude showed that Hg° exhibited a relatively constant vertical profile centered around 100 ppqv. Highly concentrated pollution plumes emanating from the Mexico City urban agglomeration revealed that mixing ratios of Hg° as large as 500 ppqv were related to combustion tracers such as CO, but not SO2 which …

Large-Amplitude Temperature Waves In The Upper Atmosphere, Jarron Lembke, Vincent B. Wickwar Apr 2008

Large-Amplitude Temperature Waves In The Upper Atmosphere, Jarron Lembke, Vincent B. Wickwar

Posters

Recent LIDAR research at USU found a noctilucent cloud (NLC) near the minimum of a large-amplitude temperature wave in the upper mesosphere. Such a large-amplitude wave had not been seen previously. Initial analysis suggested that this wave might be related to the diurnal tide, but greatly amplified. This research set out to learn whether these waves are a common feature. Large waves or temperature “bumps” exceeding 10 K were found in more than half the observations. A later stage will be to see if they are linked to the tides.

High-Precision, High-Accuracy Timekeeping In Distributed Survey Systems, Brian R. Calder, Rick Brennan, J Marcus, C Malzone, Peter Canter Apr 2008

High-Precision, High-Accuracy Timekeeping In Distributed Survey Systems, Brian R. Calder, Rick Brennan, J Marcus, C Malzone, Peter Canter

Center for Coastal and Ocean Mapping

Accurate and precise timekeeping between computers in a distributed survey system is essential to ensure adequate data quality, especially with Multibeam Echosounders (MBES) which can otherwise suffer from significant motion artefacts. We show that clock synchronisation on the order of 100-150ns (rms) is readily achievable in a modern MBES-based survey system utilising an Ethernet-based time synchronisation mechanism and some custom timekeeping software. We also show that improving the timekeeping eliminates motion artefacts in the observed bathymetry, and simplifies the patch-test procedure.
