Application Of Density Altitude Climatology To General Aviation Impacts, Thomas A. Guinn Ph.D., Daniel J. Halperin Ph.D., Sarah Strazzo Ph.D.
Application Of Density Altitude Climatology To General Aviation Impacts, Thomas A. Guinn Ph.D., Daniel J. Halperin Ph.D., Sarah Strazzo Ph.D.
Journal of Aviation/Aerospace Education & Research
Density altitude (DA) plays a key role in flight safety because it helps pilots anticipate poor aircraft performance when temperatures are warmer than standard. In this study, a 30-year climatology of DA for the conterminous United States was created using the fifth-generation European Centre for Medium-Range Weather Forecasts atmospheric reanalysis of the global climate (ERA5) dataset was applied to four separate DA-based, aircraft-performance, rules-of-thumb for general aviation (GA) flight. The goal was to demonstrate a technique to create educational visualization tools showing the variation of operational flight impacts with both month and location. Four such parameters were chosen to show …
Past The Tipping Point, But With Hope Of Return: How Creating A Geoengineering Compulsory Licensing Scheme Can Incentivize Innovation, Brooke Wilson
Past The Tipping Point, But With Hope Of Return: How Creating A Geoengineering Compulsory Licensing Scheme Can Incentivize Innovation, Brooke Wilson
Washington and Lee Journal of Civil Rights and Social Justice
This Note explores the patenting of geoengineering technologies and issues arising from the early stages of this high-risk, high-reward technology. This Note focuses on one possible solution to solving the issues surrounding the patenting of geoengineering technology: Creating a specialized compulsory licensing scheme.

Small unmanned aerial systems (sUAS) are increasingly being used to conduct atmospheric research. Because of the dynamic nature and inhomogeneity of the atmospheric boundary layer (ABL), the ability of instrumented sUAS to make on-demand 3-dimensional high-resolution spatial measurements of atmospheric parameters makes them particularly suited to ABL investigations. Both fixed-wing and multirotor sUAS have been used for ABL investigations. Most investigations to date have included in-situ measurement of thermodynamic quantities such as temperature, pressure and humidity. When wind has been measured, a variety of strategies have been used. Two of the most popular techniques have been deducing wind from inertial …
How Airport Construction Will Evolve With The Increased Effects Of Climate Change, Xavier M. Ashley
How Airport Construction Will Evolve With The Increased Effects Of Climate Change, Xavier M. Ashley
Beyond: Undergraduate Research Journal
This report addressed the effects rising global temperatures resulting from climate change have had on flight operations in their entirety. The research objective was to discover what methods could enhance climate adaptation in airport construction, as higher mean-surface temperatures have an increasingly negative effect on aircraft performance. The findings would primarily be of interest to the Federal Aviation Administration (FAA) Primary Office presiding over the planning and development of airports. Overall, the report provided a comprehensive analysis of global warming’s effects on aviation, including the implications of degraded aircraft performance and sea-level rise for coastal airports. Additionally, it examined comparative …

Do Wind Turbines Affect Weather Conditions?: A Case Study In Indiana, Meghan F. Henschen, Brittany Herrholtz, Lacey Rhudy, Kathryn Demchak, Brian Doogs, Joshua Holland, Erik Larson, Johnny Martin, Matthew Rudkin
The Journal of Purdue Undergraduate Research
Wind turbines are becoming increasingly widespread in the United States as the world looks for cleaner sources of energy. Scientists, policymakers, and citizens have strong opinions regarding the positive and negative effects of wind energy projects, and there is a great deal of misinformation about wind energy circulating on the Web and other media sources. The purpose of this study is to gain a better understanding of how the rotation of hundreds of turbines can influence local weather conditions within a wind farm and in the surrounding areas. This experiment measures temperature, atmospheric pressure, wind speed, wind direction, relative humidity, …

Migratory Movements Of Emus And Control Efforts, John L. Long, T. J. Tozer
Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH little data has been recorded on movements or migrations of the Emu (Dromaius novea-hollandiae), it is well known throughout the farming community that some such movement occurs in September and October in most years at least.
