Selection Of A Reanalysis Meteorological Product For Use In Solar Resource Assessment, Anthony Lopez

Geography and the Environment: Graduate Student Capstones

The U.S. Department of Energy’s National Renewable Energy Laboratory and collaborators are updating the National Solar Radiation Database with the next-generation satellite-based solar resource assessment known as the Physical Solar Model (PSM). This is part of an effort to achieve NREL and DOE’s goal to make solar energy technologies cost competitive with other forms of energy in the United States. Required in this effort is the selection of an appropriate meteorological reanalysis product- that provides critical inputs for solar energy estimation. This analysis quantitatively and qualitatively assessed the spatial and temporal accuracy of three meteorological reanalysis products using ground measurements. …

Modis-Derived Spatiotemporal Changes Of Major Lake Surface Areas In Arid Xinjiang, China, 2000–2014, Qingting Li, Linlin Lu, Cuizhen Wang, Yingkui Li, Yue Sui, Huadong Guo

Faculty Publications

Inland water bodies, which are critical freshwater resources for arid and semi-arid areas, are very sensitive to climate change and human disturbance. In this paper, we derived a time series of major lake surface areas across Xinjiang Uygur Autonomous Region (XUAR), China, based on an eight-day MODIS time series in 500 m resolution from 2000 to 2014. A classification approach based on water index and dynamic threshold selection was first developed to accommodate varied spectral features of water pixels at different temporal steps. The overall classification accuracy for a MODIS-derived water body is 97% compared to a water body derived …

An Approach To Optimal Hyperspectral And Multispectral Signature And Image Fusion For Detecting Hidden Targets On Shorelines, Charles R. Bostater

Ocean Engineering and Marine Sciences Faculty Publications

Hyperspectral and multispectral imagery of shorelines collected from airborne and shipborne platforms are used following pushbroom imagery corrections using inertial motion motions units and augmented global positioning data and Kalman filtering. Corrected radiance or reflectance images are then used to optimize synthetic high spatial resolution spectral signatures resulting from an optimized data fusion process. The process demonstrated utilizes littoral zone features from imagery acquired in the Gulf of Mexico region. Shoreline imagery along the Banana River, Florida, is presented that utilizes a technique that makes use of numerically embedded targets in both higher spatial resolution multispectral images and lower spatial …

Tracking Of Karst Contamination Using Alternative Monitoring Technologies: Hidden River Cave Kentucky, Caren Raedts, Christopher Smart

Sinkhole Conference 2015

Karst groundwater contamination presents great challenges for efficient monitoring because of rapid, discrete transport and the diversity of contaminants. Here a low cost approach is described and applied to Hidden River Cave, Kentucky, where a long history of contamination has been experienced. Local knowledge was acquired through informal interviews and coupled with observations of contaminant residues, faunal distributions and fluorescence spectra in the cave. The resulting patterns were interpreted using Google Earth and Street View to identify specific contaminant sources in the affected sub-catchment of the cave. Despite success in matching contaminant sources with the contamination history and pattern, the …

‘Capitalism A Nuh’ Wi Frien’. The Formatting Of Farming Into An Asset, From Financial Speculation To International Aid, Luigi Russi, Tomaso Ferrando

Catalyst: A Social Justice Forum

This paper deciphers the formatting of farming into an asset by tracking the modalities by which financial calculation is enabled across different sites of agency.

The first focus of our analysis are commodity futures markets, which have witnessed a double spike in prices in 2008 and in 2012. In the paper, we look at these hikes as the outcome of endogenous dynamics, caused by the changing makeup of market participants after 2000, which turned futures markets into resources for hedging commodity index-linked derivative products.

We subsequently analyse the increasing reliance on financial actors placed by public development agencies that channel …

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …

Classification, Visualization, And Analysis Of The Islamic State’S Narrative, Steven D. Bixler

Geography and the Environment: Graduate Student Capstones

The Islamic State (IS) declared the establishment of a Caliphate on June 29, 2014 in Mosul, Iraq. Since that declaration, IS has communicated a four-part narrative to the global community through Dabiq magazine, its e-publication. Each of the ten editions of Dabiq has provided insight into IS’s aspirations and reinforced its message of rejecting post-colonial structures. Critical to realizing its objective is establishing a foothold for the Caliphate through jihad (holy war), establishing legitimacy through jamaah (governance), achieving tawhid (unity), and expanding through hijrah (immigration). Each publication contains these narrative elements to document IS’s progress. Classifying, visualizing, and mapping will …

Migration Governance And Migration Rights In The Southern African Development Community (Sadc): Attempts At Harmonization In A Disharmonious Region, Belinda Dodson, Jonathan Crush

Southern African Migration Programme

This paper examines prospects for enhanced regional migration governance and protection of migrants’ rights in the Southern African Development Community (SADC). Migration in this region is substantial in scale and diverse in nature, incorporating economic, political and mixed migration flows. In addition to movements between countries within the region, migrants also come from across the African continent and even further afield. At its foundation in 1992, SADC as an institution initially embraced a vision of intra-regional free movement, but this has not become a reality. If anything, there has been a hardening of anti-migrant attitudes, not least in the principal …

Online Mapping Tools For Geolocating Amish Settlements, Andrew M. Wilson, Brian J.B. Lonabocker, Megan E. Zagorski

Environmental Studies Faculty Publications

This technical note demonstrates the value of using online mapping tools as a method of geolocating Amish settlements. Primarily using freely available Bing and Google maps and published lists of the addresses of Amish ministers, we geolocated 1,362 Amish households in Ohio and 1,203 in Pennsylvania, representing about 10% of Amish households in those states. From these data we were able to derive a population density map of the Amish across Ohio and Pennsylvania. We caution that our map is merely a model and based on several assumptions, but the product is a finer resolution map of Amish distribution than …

Modeling Vegetation Mosaics In Sub-Alpine Tasmania Under Various Fire Regimes, Gabriel I. Yospin, Samuel W. Wood, Andrés Holz, David M.J.S. Bowman, Robert E. Keane, Cathy Whitlock

Geography Faculty Publications and Presentations

Western Tasmania, Australia contains some of the highest levels of biological endemism of any temperate region in the world, including vegetation types that are conservation priorities: fire-sensitive rainforest dominated by endemic conifer species in the genus Athrotaxis; and fire-tolerant buttongrass moorlands. Current management focuses on fire suppression, but increasingly there are calls for the use of prescribed fire in flammable vegetation types to manage these ecosystems. The long-term effects of climate and alternative management strategies on the vegetated landscape are unknown. To help identify controls over successional trajectories, we parameterized a spatially explicit landscape-scale model of vegetation and fire …

Short-Tailed Temperature Distributions Over North America And Implications For Future Changes In Extremes, Paul C. Loikith, J. David Neelin

Geography Faculty Publications and Presentations

Some regions of North America exhibit nonnormal temperature distributions. Shorter-than-Gaussian warm tails are a special subset of these cases, with potentially meaningful implications for future changes in extreme warm temperatures under anthropogenic global warming. Locations exhibiting shorter-than-Gaussian warm tails would experience a greater increase in extreme warm temperature exceedances than a location with a Gaussian or long warm-side tail under a simple uniform warm shift in the distribution. Here we identify regions exhibiting such behavior over North America and demonstrate the effect of a simple warm shift on changes in extreme warm temperature exceedances. Some locations exceed the 95th percentile …

Spatial Information Divergence: Using Global And Local Indices To Compare Geographical Masks Applied To Crime Data, Ourania Kounadi, Michael Leitner

Faculty Publications

Advances in Geographic Information Science (GISc) and the increasing availability of location data have facilitated the dissemination of crime data and the abundance of crime mapping websites. However, data holders acknowledge that when releasing sensitive crime data there is a risk of compromising the victims' privacy. Hence, protection methodologies are primarily applied to the data to ensure that individual privacy is not violated. This article addresses one group of location protection methodologies, namely geographical masks that are applicable for crime data representations. The purpose is to identify which mask is the most appropriate for crime incident visualizations. A global divergence …

The purpose of this Capstone will be to provide city, county, and eventually state, entities with the knowledge to better identify those areas which would fall under the auspice of the Healthy Food Financing Initiative, as laid out in a report by the United States Department of Agriculture’s Economic Research Council on “Food Deserts.” Food deserts are those areas in which access to nutritious foods is limited by distance, by lack of transportation, or both. Food deserts have also been linked to obesity in children and adults, with the attendant health problems. With this knowledge, starting at the local level, …

American Dreamer: First-Time Homeownership And The Affective Geographies Of Dwelling, Stephen Boatright

Dissertations, Theses, and Capstone Projects

This research examines the experiences novice homebuyers in New York City and Oakland, CA have during the home search and decision-making processes. Using a mixed-method approach that combines ethnography with critical discourse analysis and non-representational theory, this work examines the ideology of homeownership as well as the tensions that stem from its emotional affordances. It addresses a lacuna in the housing literature regarding the turbulent everyday emotional tensions that buyers confront as they navigate the highly professionalized real estate industry. Homeownership is lauded for being a relatively low-risk tool for highly leveraged investment; however, using data drawn from a series …

Aerosol And Urban Heat Island Effects On Warm Cloud-Top Shortwave Infrared Reflectance And Visible Albedo, Heather Glickman-Eliezer

Dissertations, Theses, and Capstone Projects

This study uses ten years of Geostationary Operational Environmental Satellite (GOES) data (1999-2009) to assess urban effects of anthropogenic aerosols and Urban Heat Island (UHI) on cloud-top radiative properties of optically thick clouds. GOES images at noon local time of channels 1, 2, and 4 are used to calculate visible albedo, and shortwave infrared reflectance at 3.9-µm. Cloud-top particle radius is inversely related with SWIRR. Albedo and cloud fraction are measured for cold and warm clouds, and SWIRR is used as a particle-radius proxy for warm clouds only. AERONET fine-mode particle retrievals (fAOD) from the CCNY station are used for …

China's Nine-Dashed Map: Continuing Maritime Source Of Geopolitical Tension, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

The South China Sea (SCS) is becoming an increasingly contentious source of geopolitical tension due to its significance as an international trade route, possessor of potentially significant oil and natural gas resources, China’s increasing diplomatic and military assertiveness, and the U.S.’ recent and ongoing Pacific Pivot strategy. Countries as varied as China, Taiwan, the Philippines, Indonesia and other adjacent countries have claims on this region’s islands and natural resources. China has been particularly assertive in asserting its SCS claims by creating a nine-dash line map claiming to give it de facto maritime control over this entire region without regard to …

No time to waste: Crowdsourcing global wastewater treatment data

Worldwide, over 80 percent of wastewater is discharged into water bodies without undergoing treatment, severely impairing human well-being and ecosystem vitality along the way. National performance on wastewater treatment is difficult to quantify and is poorly understood due to a lack of common definitions, poor data collection standards, and limited historical data. To address this, the Yale Environmental Performance Index (EPI), a research group that produces a biennial ranking of country-level environmental performance, developed a first-of-its kind national wastewater treatment indicator.[1]

The indicator assesses wastewater treatment performance for 183 countries, …

Moving Fluid Mud Sondes, Optical And Acoustic Sensing Methods In Support Of Coastal Waterway Dredging, Charles R. Bostater, Tyler A. Rotkiske

Ocean Engineering and Marine Sciences Faculty Publications

Airborne, Satellite and In-Situ optical and acoustical imaging provides a means to characterize surface and subsurface water conditions in shallow marine systems. An important research topic to be studied during dredging operations in harbors and navigable waterways is the movement of fluidized muds before, during and after dredging operations. The fluid movement of the surficial sediments in the form of flocs, muck and mud is important to estimate in order to model the transport of solids material during dredging operations. Movement of highly turbid bottom material creates a lutocline or near bottom nephelometric layers, reduces the penetration of light reaching …

Stone Walls And Shopping Malls: Retail Landscapes In The Bluegrass, Jason Richards

Kaleidoscope

This paper is an analysis of the recent use of veneered stone walls in the contemporary retail landscapes of the Bluegrass. These walls have been used in conjunction with other elements of the region’s landscape symbol vocabulary to re-create the equine landscape of Central Kentucky in commercial spaces. They seek to evoke the region’s symbolic landscape of wealthy horse estates, utilizing their inaccessibility to elicit an associative attitude of aspiration in the shopper. But they also speak to the values of the businesses and citizens who produce them. The earliest of these walls were found in the street frontage and …

Evapotranspiration In The Nile Basin: Identifying Dynamics, Trends, And Drivers 2002-2011, H. Alemu, A. T. Kaptué, G. B. Senay, M. C. Wimberly, Geoffrey Henebry

Natural Resource Management Faculty Publications

Analysis of the relationship between evapotranspiration (ET) and its natural and anthropogenic drivers is critical in water-limited basins such as the Nile. The spatiotemporal relationships of ET with rainfall and vegetation dynamics in the Nile Basin during 2002–2011 were analyzed using satellite-derived data. Non-parametric statistics were used to quantify ET-rainfall interactions and trends across land cover types and subbasins. We found that 65% of the study area (2.5 million km2) showed significant (p < 0.05) positive correlations between monthly ET and rainfall, whereas 7% showed significant negative correlations. As expected, positive ET-rainfall correlations were observed over natural vegetation, mixed croplands/natural vegetation, and croplands, with a few subbasin-specific exceptions. In particular, irrigated croplands, wetlands and some forests exhibited negative correlations. Trend tests revealed spatial clusters of statistically significant trends in ET (6% of study area was negative; 12% positive), vegetation greenness (24% negative; 12% positive) and rainfall (11% negative; 1% positive) during 2002–2011. The Nile Delta, Ethiopian highlands and central Uganda regions showed decline in ET while central parts of Sudan, South Sudan, southwestern Ethiopia and northeastern Uganda showed increases. Except for a decline in ET in central Uganda, the detected changes in ET (both positive and negative) were not associated with corresponding changes in rainfall. Detected declines in ET in the Nile delta and Ethiopian highlands were found to be attributable to anthropogenic land degradation, while the ET decline in central Uganda is likely caused by rainfall reduction.
