Uncertainties in climate data analysis
… but also what we do not know and by how much. In climate data analysis, this involves an accurate specification of measured quantities and a consequent analysis that consciously propagates the measurement errors at each step. The dissertation presents a thorough analytical method to quantify …

Generalized Bathtub Hazard Models for Binary-Transformed Climate Data
… framework to time series methods as applied to climate data. Data collected from the Kentucky Mesonet will be used to study the distributional properties of the duration of high and low-energy wind events relative to an arbitrary threshold. Our objectiveswere to fit bathtub models proposed in …

Application of nonlinear dimensionality reduction to climate data for prediction
… a physically appealing method of decomposing the data, as it substitutes the euclidean distances in the manifold by an approximation of the geodesic distances. We expect that this method could be successfully applied to other oscillatory extended systems and, in particular, to meteorological …

Wildfire Risk Assessment Using Convolutional Neural Networks and Modis Climate Data
… costing governments billions in funding. As climate change intensifies drought volatility across the Western United States, wildfires are likely to become increasingly severe. Wildfire risk assessment and hazard maps are currently employed by fire services, but can often be outdated. This …

A Study of Dimensionality Reduction Techniques and its Analysis on Climate Data
… variety of domains such as pattern recognition, data compression, image segmentation and clustering. Different methods exploit different features in the data to reduce dimensionality. Principle component Analysis is one such method that exploits the variance in data to embed data onto a lower …

Science and the Structure of Social Experiment: A Socio-political Study of Climate Data Infrastructure
… this literature see in such media phenomena as climate change denial, vaccine hesitancy, and resistance to public health and environmental measures more generally a growing trend of public doubt over well-established, consensus generating scientific research. Each of these analyses has its own …

What can we learn from climate data? : Methods for fluctuation, time/scale and phase analysis
… observe nature and formulate theories about the climate system. Since some decades powerful computers are capable to simulate the past and future evolution of climate. Time series analysis tries to link the observed data to the computer models: Using statistical methods, one estimates …

Multivariate Extreme Value Theory with an application to climate data in the Western Cape Province
… in any region. Together with an ever-changing climate it has become markedly noticeable that there is an upward trend in extreme weather conditions. The aim of this study is to evaluate the efficacy of univariate and multivariate extreme value theory models on climate data in the Western Cape …

Evaluation of climate data sources and investigation of performance prediction models for mechanistic-empirical pavement designs
… recent enhancements include addition of MERRA climate data (satellite-based data provided through NASA), a reflective-cracking model for overlay performance prediction, a tool to design short jointed plain concrete pavement (SJPCP) over asphalt concrete (AC), and major bugs were resolved to …

Analysis of Historical Cooperative Observation Program (COOP) Climate Data Through Trend and Correlation Determination for Selected South Dakota Sites and Comparisons of COOP Sensors with the Automated Weather Data Network (AWDN) Remote Sensors
… studies COOP and AWDN weather observation data to increase the understanding of climate at several locations in South Dakota. In the first study, frozen soil temperatures were studied for Cottonwood, SD. The timing of when soil was considered frozen and thawed each year was determined which …

Feeling the Climate Crisis
This project visualizes the ongoing climate crisis through the means of kinetic sculptures that are made with found natural objects juxtaposed with electromechanical elements. Together they create movement patterns that express climate data. The project attempts to create an experience that allows …

Comparative analysis between MERRA and updated MEPDG climate database in the state of Tennessee
… Pavement Design Guide (MEPDG) addresses climate effects on pavement design in a comprehensive way, which allows for investigating the effect of climate inputs on pavement performance. However, it requires detailed climate inputs, which might not be available for most of the state DOT. The …

INCORPORATING CLIMATE CHANGE PROJECTIONS INTO RISK MEASURES OF INDEX-BASED INSURANCE
… a complete working example of using regional climate model projections to estimate the changing risks of temperature index-based insurance products defined for a series of locations in California. This region is a major agricultural producer for the US and the world. The climate model …

Assessing maize water requirements in the context of climate change uncertainties over southern Africa
Climate change studies are subject to high uncertainties partly resulting from data reliability. This study investigates the challenges of using statistical downscaled climate data to examine the likely impacts of climate change on maize growth in southern Africa in the context of these …

Bias Correction and Downscaling of Climate Model Outputs Required for Impact Assessments of Climate Change in the U.S. Northeast
<p>Global Climate Models (GCMs) are the typical sources of future climate data required for impact assessments of climate change. However, GCM outputs are related to model-related uncertainties and involve a great deal of biases. Bias correction of model outputs is, therefore, necessary before …

Potential past and future tree migration responses to climate change
Anthropogenic climate change is leading to dramatic fluctuations of essential climate dynamics and has become a major threat to modern ecosystem services and biodiversity because of its magnitude and rate of change. Climate is a well-known key constraint of species and ecosystem functions affecting …

A Spatial Suitability Assessment of Maize and Tobacco in Response to Temperature and Rainfall Changes in Zimbabwe
Climate is changing, and this change poses threats to the agricultural sector. The impacts of climate are expected to become more extreme as the earth warms, and this change will affect climate suitability for different types of crops. The degree to which an increase in temperature patterns and …

Model parameter uncertainty and climate change effects in hydropower vulnerability projections
… vulnerable to drought conditions exacerbated by climate change, with reservoir levels falling below minimum power pool thresholds. An under-examined component of this vulnerability is how model parameter uncertainty affects simulated reservoir levels. Here, I investigate the extent to which …

Attribution of the 2015-2016 hydrological drought in KwaZulu-Natal to anthropogenic climate change
… on the environment, society and the economy. Climate change is predicted to exacerbate extreme events such as droughts that would adversely affect already vulnerable regions such as KZN. The main aim of this study is to implement the attribution procedure, to determine if climate change has …

Outside the Coffee Belt: A Study on the Suitability and Sustainability of Coffee Plants in California Due to Climate Change Using GIS
<p>California has a unique climate that is suitable for growing a variety of agricultural crops. As stated by the California Department of Food and Agriculture, California’s agricultural abundance includes more than 400 commodities, and of these, over a third of the vegetables and three-quarters of …
