Remote Sensing Of Cloud Properties Using Oxygen A-Band Spectral Measurements, Siwei Li Jan 2012

Remote Sensing Of Cloud Properties Using Oxygen A-Band Spectral Measurements, Siwei Li

Legacy Theses & Dissertations (2009 - 2024)

Clouds play an important role in the climate system through their radiative effects and their vital link in the hydrological cycle. Detailed knowledge of the three dimensional (3-D) distribution of cloud macrophysical and microphysical properties is crucial to properly characterize radiative forcing by clouds and to quantify the response of the climate. In this study, a multi-layer cloud detection algorithm is developed by utilizing photon path length distributions retrieved from oxygen A-band spectral measurements. Case studies from measurements at the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site demonstrate that this photon path length method can detect multi-layer clouds …


The Analytic Reconciliation Of Classic Mayan Elite Pottery : Squaring Pottery Function With Form, Adornment, And Residual Contents, Jennifer Ann Loughmiller-Newman Jan 2012

The Analytic Reconciliation Of Classic Mayan Elite Pottery : Squaring Pottery Function With Form, Adornment, And Residual Contents, Jennifer Ann Loughmiller-Newman

Legacy Theses & Dissertations (2009 - 2024)

This dissertation presents a multidisciplinary means of determining the actual content (foodstuff, non-foodstuff, or lack of contents) of Classic Mayan (A.D. 250-900) vessels. Based on previous studies that have identified the residues of foodstuffs named in hieroglyphic texts (e.g. cacao), this study is designed to further investigate foodstuff residues in the elite vessels indicated by text or image to contain those residues, and the methods employed for residue characterization. Prior to studies utilizing residue analysis, the content of Classic Maya vessels largely had long been inferred largely by ethnographic analogy, associating specific vessel forms with specific uses based on ethnographic …


Modeling For Policy Change : A Feedback Perspective On Improving The Effectiveness Of Coastal And Marine Management, Donald David Robadue Jr. Jan 2012

Modeling For Policy Change : A Feedback Perspective On Improving The Effectiveness Of Coastal And Marine Management, Donald David Robadue Jr.

Legacy Theses & Dissertations (2009 - 2024)

Those advocating for effective management of the use of coastal areas and ecosystems have long aspired for an approach to governance that includes information systems with the capability to predict the end results of various courses of action, monitor the impacts of decisions and compare results with those predicted by computer models in order to suggest alterations in the actions needed if the goals are not being achieved. This dissertation draws on system dynamics modeling, content analysis and professional experience to explore four decades of experience in the United States as well as international cases to reveal lessons and strategies …
