Downscaling Daily Maximum And Minimum Air Temperature In The Midwestern Usa: A Hybrid Empirical Approach, Justin T. Schoof, S C. Pryor, S M. Robeson

Publications

A new hybrid empirical downscaling technique is presented and applied to assess 21st century projections of maximum and minimum daily surface air temperatures (Tmax, Tmin) over the Midwestern USA. Our approach uses multiple linear regression to downscale the seasonal variations of the mean and standard deviation of daily Tmax and Tmin and the lag-0 and lag-1 correlations between daily Tmax and Tmin based on GCM simulation of the large-scale climate. These downscaled parameters are then used as inputs to a stochastic weather generator to produce time series of the daily Tmax and Tmin at 26 surface stations, in three time …

Dynamically And Statistically Downscaled Seasonal Simulations Of Maximum Surface Air Temperature Over The Southeastern United States, Young-Kwon Lim, D W. Shin, Steven Cocke, T E. Larow, Justin T. Schoof, James J. O'Brien, Eric P. Chassignet

Publications

Coarsely resolved surface air temperature (2 m height) seasonal integrations from the Florida State University/Center for Ocean-Atmospheric Prediction Studies Global Spectral Model (FSU/COAPS GSM) (~1.8º lon.-lat. (T63)) for the period of 1994 to 2002 (March through September each year) are downscaled to a fine spatial scale of ~20 km. Dynamical and statistical downscaling methods are applied for the southeastern United States region, covering Florida, Georgia, and Alabama. Dynamical downscaling is conducted by running the FSU/COAPS Nested Regional Spectral Model (NRSM), which is nested into the domain of the FSU/COAPS GSM. We additionally present a new statistical downscaling method. The rationale …

This study assessed the horizontal and vertical accuracy of the Applanix Digital Sensor System (DSS"") 301 orthophotographs. The study area was located on the University of Arkansas at Monticello campus and included 950 acres. To assess the spatial accuracy of the DSS, 56 Ground Control …

Visual Representations Of The Spatial Relationship Between Bermuda High Strengths And Hurricane Tracks, Jason T. Knowles, Michael Leitner

Faculty Publications

The 2004 and 2005 hurricane seasons dramatically demonstrated the magnitude of the societal significance of hurricanes, negatively impacting on all scales from the personal to the national. Although definitive identification of the forcing mechanisms controlling hurricane tracks and landfall patterns remains elusive, increasing evidence supports the hypothesis that the increase in hurricane activity along the Gulf Coast is due to a southwestward shift in the position of the Bermuda High. This research uses multiple visualization techniques to explore the spatial correlation between Bermuda High strengths - as interpreted from the North Atlantic Oscillation (NAO) index - and hurricane tracks. Using …

Use Of The Global Positioning System In The Field Recovery Of Scattered Human Remains, Ginesse A. Listi, Mary H. Manhein, Michael Leitner

Faculty Publications

This study examines the Global Positioning System (GPS) as a tool for field mapping of scattered human remains or other materials in forensic investigations. Two aspects of the GPS are considered: (1) the level of accuracy that can be obtained using a mid-priced GPS unit, and (2) the effectiveness of using the GPS to map scattered materials. The positional accuracy of the GPS receiver was tested using a National Geodetic Survey (NGS) point located in Baton Rouge, LA. The utility of the GPS for mapping was investigated by setting up a mock field recovery and mapping the remains using both …

Riding The Wheel: Selling American Women Mobility And Geographic Knowledge, Christina E. Dando

Geography and Geology Faculty Publications

The bicycle's “prime” was a mere decade, 1890-1900, but in this brief window, it had a profound impact on American women’s lives. This paper will examine the role of the media in transforming women's relationship to their world, altering how, where and why they moved through the landscape, drawing from work on cartographic culture, actor-network theory and consumption and mass culture. Through popular magazine articles, stories, advertisements, and maps, American women (as well as men) were “informed” of the possibilities the bicycle had to offer, modeling geographic mobility, greater spatial awareness, and the practice of both cartography and landscape. Women …

Model Estimation Of Land-Use Effects On Water Levels Of Northern Prairie Wetlands, Richard A. Voldseth, W.Carter Johnson, Tagir Gilmanov, Glenn R. Guntenspergen, Bruce V. Millett

Natural Resource Management Faculty Publications

Wetlands of the Prairie Pothole Region exist in a matrix of grassland dominated by intensive pastoral and cultivation agriculture. Recent conservation management has emphasized the conversion of cultivated farmland and degraded pastures to intact grassland to improve upland nesting habitat. The consequences of changes in land-use cover that alter watershed processes have not been evaluated relative to their effect on the water budgets and vegetation dynamics of associated wetlands. We simulated the effect of upland agricultural practices on the water budget and vegetation of a semipermanent prairie wetland by modifying a previously published mathematical model (WETSIM). Watershed cover/landuse practices were …

Spatial And Morphological Change Of Eliot Glacier, Mount Hood, Oregon, Keith Michael Jackson

Dissertations and Theses

Eliot Glacier is a small (1.6 km²), relatively well-studied glacier on Mount Hood, Oregon. Since 1901, glacier area decreased from 2.03 ± 0.16 km² to 1.64 ± 0.05 km² by 2004, a loss of 19%, and the terminus retreated about 600 m. Mount Hood's glaciers as a whole have lost 34% of their area. During the first part of the 20th century the glacier thinned and retreated, then thickened and advanced between the 1940s and 1960s because of cooler temperatures and increased winter precipitation and has since accelerated its retreat, averaging about 1.0 m a^{-1 …}

What Does Not Kill You: Historical Materialism And The Body, Reecia Orzeck

Faculty Publications - Geography, Geology, and the Environment

In recent decades the body has become an important object of inquiry within the discipline of geography, as it has within the humanities and social sciences more generally. Though often critical of the tenets of poststructuralism, Marxist geographers have responded with enthusiasm to the imperative that we denaturalize the body, and have demonstrated a capacious store of resources available to this task. Building on recent efforts by geographers to conceptualize a Marxist theory of the body, this paper moves in two directions. Aligning myself with those interested in demonstrating the constructedness of the body, I begin by arguing both that …

Tree Species Identification In An Urban Environment Using A Data Fusion Approach, Matthew A. Voss

Dissertations and Theses @ UNI

This thesis explores a data fusion approach combining hyperspectral, LiDAR, and multispectral data to classify tree species in an urban environment. The study area is the campus of the University of Northern Iowa.

In order to use the data fusion approach, a wide variety of data was incorporated into the classification. These data include: a four-band Quickbird image from April 2003 with 0.6m spatial resolution, a 24-band AISA hyperspectral image from July 2004 with 2m spatial resolution, a 63-band AISA Eagle hyperspectral image from October 2006 with lm spatial resolution, a high resolution, multiple return LiDAR data set from April …

Impact Of Lidar Nominal Post-Spacing On Dem Accuracy And Flood Zone Delineation, George T. Raber, John R. Jensen, Michael E. Hodgson, Jason A. Tullis, Bruce A. Davis, Judith Berglund

Faculty Publications

Lidar data have become a major source of digital terrain information for use in many applications including hydraulic modeling and flood plane mapping. Based on established relationships between sampling intensity and error, nominal post-spacing likely contributes significantly to the error budget. Post-spacing is also a major cost factor during lidar data collection. This research presents methods for establishing a relationship between nominal post-spacing and its effects on hydraulic modeling for flood zone delineation. Lidar data collected at a low post-spacing (approximately 1 to 2 m) over a piedmont study area in North Carolina was systematically decimated to simulate datasets with …

An Institutional Analysis Of Oil And Gas Sector Development And Environmental Management In The Yukon Territory, Jason C. May

Theses and Dissertations (Comprehensive)

This thesis investigates the ways in which oil and gas development priorities and concern for the environment are integrated within strategic planning and management frameworks, and how associated conflict is addressed, in a case study of the Yukon. Because substantial ground-based oil and gas activity is yet to occur in the territory, a thorough understanding of the institutions and institutional arrangements set to govern future oil and gas development is a valuable tool for gauging the capacity to integrate these priorities. Therefore, this thesis employs the Institutional Analysis and Development (IAD) framework to analyze the legislation, regulations, policies, and institutions …

The Promises And Prospects Of Geography In Higher Education, Lily Kong

Research Collection School of Social Sciences

The idea for this JGHE symposium came to me as I reflected on the spatial turn in the humanities and social sciences, and felt encouraged by the growing influence of geography in the intellectual spaces of other disciplines. Amidst positive thoughts, I wondered if the institutional position of the discipline had strengthened with its recently enhanced intellectual position, and what the geography of geography's institutional presence and strength was. For sure, anecdotal stories circulate regarding the opening or closure of a geography department, a renaming, a split and so forth…. A symposium of papers from different parts of the world …

Linking Research And Policy: The Case Of Ghana's Rice Trade Policy, Aharon Degrassi

Faculty Publications, Geography

Agricultural trade policies, in particular import tariffs to protect domestic production, constitute a highly contested field of agricultural policy. In view of the recent focus on “evidence-based policy making†in the international development debate, the question arises as to which extent research-based evidence is used in such policy decisions, and which role research plays as compared to other political factors. Against this background, this paper seeks to examine and explain research-policy linkages in the case of rice tariff reform in Ghana. It is based on literature reviews and 70 interviews. The paper uses a historical cultural political economy approach, and …

Lightning Signature Assessment To Forecast Tornado Formation, Mary Snow, Richard Snow, Nicole Kufa

Publications

Recent research suggests that a maximum rate of lightning strikes occurs at least 15 to 20 minutes prior to tornado formation within a supercell storm. These maxima are associated with strengthening updrafts as they appear in radar measurements. An increase in lightning rates correlates with an increase of shear in the lower part of the storm. In combination with a strong updraft or downdraft, this shear can provide the ingredients for rotation and possibly a tornado. Polarity reversal of lightning around the time of tornado touchdown also has been examined. Thus, increasing lightning flash rates and reversal of lightning strike …

Geography's Place In Higher Education In Singapore, Lily Kong

Research Collection School of Social Sciences

Unlike the other papers in this symposium, which deal with countries where there are large numbers of universities, and comparison can be made over time and across space of geography's place in higher education, this paper focuses on a country that was for a long time described as a 'one-university town': Singapore. What interesting story call there be when geography's presence in higher education is so circumscribed? In this paper, the author illustrates how geography's,fate in higher education in Singapore is closely bound up with developments in other parts of the world, not unlike the way in which the country's …

The Battle Over Our Land: Urbanization Versus Farmland Preservation In The Greater Golden Horseshoe, Kali Mikulica

Theses and Dissertations (Comprehensive)

Urban sprawl continues to advance further and further into the countryside, as individuals trade cramped urban spaces for much larger rural lots and longer commutes to work. This increased sprawl permanently converts productive agricultural land to urban uses, especially in regions surrounding rapidly expanding cities. It is for this reason that farmland preservation has become a significant issue for policy officials in recent decades. According to the literature, there are numerous methods of protecting prime agricultural land in the face of urbanization; however there are few studies that focus on how these different policy techniques affect farmers. The Ontario government …

Evapotranspirative Controls In A Low Arctic Tundra Environment, Daring Lake, Nwt, Canada, Shawn Lecompte

Theses and Dissertations (Comprehensive)

Determining the extent to which changes in vegetation assemblages influence evapotranspiration in the Arctic could potentially contribute to a more realistic estimation of evaporation in a warming climate.

This project aims to determine whether variations in PET and AET rates measured at six tundra vegetation communities can be attributed to the differing vegetation. This will provide a more realistic estimate of change in the water and energy cycles, as well as evaporative processes for a warmer future, caused by enhanced global warming. Predictions of temperature and precipitation regarding future climate in Canada’s Western low Arctic vary greatly. The majority of …

Biomass Estimation And Classification Of Secondary Succession Using Radar And Optical Remote Sensing Data Based On Textural And Spectral Analysis In Amazonia, Ping Jiang

All-Inclusive List of Electronic Theses and Dissertations

Deforestation that happened during past decades in the Amazon Basin has been potentially affecting the global climate and carbon-cycle by contributing a vast amount of carbon into the atmosphere. Above-ground biomass (AGB) estimation of secondary successional and mature forests using remote sensing technology has been attracting scientists' attention. Optical sensor data are sensitive to forest canopies only, and therefore have limitations in AGB estimation, especially for tropical forests with complex structures and abundant species. Radar signals have the ability to penetrate canopies to detect the sub-layers of forests, and therefore potentially have a better performance in AGB estimation. Based on …
