Coupling of Integrated Biosphere Simulator to Regional Climate Model version 3
… Biosphere Simulator (IBIS) to Regional Climate Model version 3 (RegCM3), and an assessment of the coupled model (RegCM3-IBIS). RegCM3 is a 3-dimensional, primitive equation limited area model used throughout the world for seasonal predictability and regional climate studies. IBIS is a …

Temperature trends of the Late Cambrian through the Middle Ordovician : implications for Ordovician climate and biodiversification
… Phanerozoic--the end Ordovician mass extinction. Climate change has been invoked as a contributing factor to both events. Much research has focused on the end Ordovician extinction and thus, paleotemperatures of the last 15 million years of the period are relatively well documented. Data for the …

Evaluating multi-satellite chlorophyll-a datasets an ocean colour case study within the Southern Benguela
… Initiatives such as the Ocean Colour Climate Change Initiative (OC-CCI) produce merged multi-satellite products to create consistent long-term time-series datasets for climate studies at a global scale. Their ability to handle variable in-water conditions is critical for their mission …

Arctic Cloud, Radiation and their Interactions with Sea Ice
… is a convenient and necessary tool in the Arctic climate study. However, their uncertainties should be quantified first before utilizing these reanalyses in Arctic climate studies. Therefore, we first estimate the uncertainties of Arctic cloud and radiative properties in five global reanalysis …

Bias correction of global circulation model outputs using artificial neural networks
Climate studies and effective environmental management plans require unbiased climate datasets. This study develops a new bias correction approach using a three layer feedforward neural network to reduce the biases of climate variables (temperature and precipitation) over northern South America. …

Paleosols as Holocene proxy climate indicators, McLean County, North Dakota
… has provided an excellent opportunity for paleoclimate reconstruction. Analyses included texture, stable carbon, radiocarbon, pollen, and phytoliths. The variations in these properties between individual soil horizons served to reconstruct the former environments of each soil horizon. </p> <p> …

Trend Reversal in Lake Michigan Contribution to Snowfall
… the Laurentian Great Lakes impact the region’s climate is by augmenting snowfall in downwind locations during autumn and winter months. Among many negative consequences, this surplus of snow can cause substantial property damage to homes and can escalate the number of traffic accident-related …

Equilibration of an atmosphere by geostrophic turbulence
A major question for climate studies is to quantify the role of turbulent eddy fluxes in maintaining the observed atmospheric mean state. It has been argued that eddy fluxes keep the mid-latitude atmosphere in a state that is marginally critical to the deepest mode of baroclinic instability, which …

A multi-criteria evaluation of land-surface models and application to semi-arid regions
… Schemes (SVATS) are used in global climate studies to simulate and help understand the complex interactions between the climate and the biosphere. There currently exists a multitude of SVATS of varying complexity differing in terms of the modeled physics and the manner and …

Asynchronous, distributed optimization for the coordinated planning of air and space assets
… impact Earth observing sensors in two use areas; climate studies and intelligence collection operations. The primary contributions of this thesis include our approach to the asynchronous and distributed nature of the problem and the development of a value function to facilitate the coordination of …

An urban weather generator coupling a building simulation program with an urban canopy model
… intended to integrate building energy and urban climate studies for the first time. It is based on the premise that at the same time buildings are affected by their urban environment, the urban climate is affected by the energy performance of buildings. To predict this reciprocal interaction, the …

Socially Perceptive Assistant Principals: A Descriptive Study of Secondary School Administrators in Johnson County, Florida
… satisfaction and may have an impact on school climate. Studies have linked leadership success with higher levels of emotional intelligence. Emotional intelligence can be split into two areas: the ability to understand and control one’s own emotions, and understanding other’s emotions and …

Study and prediction of the energy interactions between buildings and the urban climate
… interactions between buildings and the urban climate through the development and evaluation of a set of models. Based on first principles, these models include three different Urban Canopy and Building Energy Models (UC-BEMs), with different levels of detail and applications, and a novel urban …

Study On the Basin Scale Salt Exchange In the Indian Ocean Using Satellite Observations and Model Simulations
… the most important variables in the oceanic and climate studies, a gap in the Indian Ocean observing system to date has been the scarcity of surface salinity data. This study involves the use of numerical model outputs and salinity derived from satellites and Argo floats to understand the …

School Climate Study in Greater Atlanta Schools of the Georgia-Cumberland Conference
<p>School climate is a relevant topic for both public and private parochial schools to understand the value placed upon the school by the stakeholders. School climate studies are a critical component of effective education delivery in all school settings. The researcher was most interested in the …

Considering the effect of pulp chemistry during flotation on froth stability
… is of high importance in the current economic climate. Studies have shown that the pulp phase chemistry has a strong effect on the froth phase and therefore it is necessary to investigate how the manipulation of pulp chemistry factors can improve flotation performance. Research into the …

Optical characterisation of Southern Ocean phytoplankton
… a period of years to decades, as is required for climate studies. In many cases, these are the primary systematic observations available for chronically undersampled marine systems such as the SO. Inversion algorithms are applied to satellite radiometry with the goal of characterising the optical …
