Download or read book An Observing System Simulation Experiment for Soil Moisture Measurements from the SMAP Radiometer written by Alexandra Georges Konings and published by . This book was released on 2009 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Soil Moisture Active Passive (SMAP) satellite, to be launched in 2013, will use both radiometer and radar data to estimate soil moisture. Improved soil moisture knowledge has many applications in hydroclimatology, numerical weather prediction, flood forecasting, and human health. In this thesis, an observing system simulation experiment (OSSE) was used to study the error structure of radiometer measurements using two different retrieval algorithms. In an OSSE, geophysical fields are used to create a model of surface emission, which is coupled to an orbital sampling module and proposed retrieval algorithms. Comparing output from the retrieval algorithm to the starting soil moisture values demonstrates retrieval error. Significant uncertainty remains about the optimal representation of the effect of dielectric mixing, soil roughness, and vegetation opacity on radiometric emissions at a given soil moisture. The effect of this uncertainty on retrieval algorithms is studied by using different representations for each term in the forward and retrieval modules of the OSSE. Uncertainty due to roughness causes less error than errors in dielectric mixing and vegetation opacity treatment. In both algorithms, the retrieval shows a spatially variable bias, which is particularly large when using a single-polarization retrieval algorithm. The spatial and temporal variation of the bias, and the implications for characterization and removal of this bias as a possible error reduction strategy, are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents three distinct pillars for analysis, design, and planning: urban water cycle and variability as the state of water being; landscape architecture as the medium for built-by-design; and total systems as the planning approach. The increasing demand for water and urban and industrial expansions have caused myriad environmental, social, economic, and political predicaments. More frequent and severe floods and droughts have changed the resiliency and ability of water infrastructure systems to operate and provide services to the public. These concerns and issues have also changed the way we plan and manage our water resources. Focusing on urban challenges and contexts, the book provides foundational information regarding water science and engineering while also examining topics relating to urban stormwater, water supply, and wastewater infrastructures. It also addresses critical emerging issues such as simulation and economic modeling, flood resiliency, environmental visualization, satellite data applications, and digital data model (DEM) advancements. Features: Explores various theoretical, practical, and real-world applications of system analysis, design, and planning of urban water infrastructures Discusses hydrology, hydraulics, and basic laws of water flow movement through natural and constructed environments Describes a wide range of novel topics ranging from water assets, water economics, systems analysis, risk, reliability, and disaster management Examines the details of hydrologic and hydrodynamic modeling and simulation of conceptual and data-driven models Delineates flood resiliency, environmental visualization, pattern recognition, and machine learning attributes Explores a compilation of tools and emerging techniques that elevate the reader to a higher plateau in water and environmental systems management Water Systems Analysis, Design, and Planning: Urban Infrastructure serves as a useful resource for advanced undergraduate and graduate students taking courses in the areas of water resources and systems analysis, as well as practicing engineers and landscape professionals.

Available in PDF, EPUB and Kindle. Book excerpt: Retrieval of soil moisture using microwave spaceborne refers to the measurement and estimation of the amount of water present in the soil using satellite-borne microwave radiometers. The microwave radiometry technology works by measuring the microwave radiation emitted by the soil surface, which is related to the soil moisture content. The data collected by these radiometers is then processed using algorithms to estimate the soil moisture content. Soil moisture information is crucial for a variety of applications, including weather prediction, drought monitoring, irrigation planning, vegetation monitoring, and water resource management. The ability to obtain soil moisture measurements on a large scale through spaceborne technology provides a powerful tool for improving our understanding of land surface processes and the water cycle. Spaceborne soil moisture retrieval has proven to be an effective method for monitoring soil moisture over large areas and has provided valuable information for numerous studies in hydrology, agriculture, and climate modeling. However, the accuracy of these estimates is dependent on several factors, including the calibration of the radiometer, the development of robust algorithms, and the availability of ground validation data. Ongoing research is focused on improving the accuracy of soil moisture retrieval from spaceborne microwave radiometers and increasing our understanding of the relationships between soil moisture and other land surface variables. Xray systems in medical science, laser scanning for atmospheric constituents, and sonar sounding of sea level. Remote sensing utilizes electromagnetic radiation as an information carrier from the target to the sensing device. It involves the interaction of electromagnetic radiations to the targeting object. The radiations, reflected, transmitted, or emitted by the object are captured by the sensors to find the target information. These sensors can be mounted on different platforms such as automotive vehicles, aircraft, rockets, hot air balloons, drones, space shuttles, and satellites. Remote sensing is part of countless possible innovations due to the roaming of the satellites around our Earth. Satellites play a crucial role in developing various technologies such as global mapping, GPS, urban planning, etc. The primary applications of remote sensing are the study of Earth's surface, Earth's atmosphere, LU/LC management, climate change monitoring, agriculture, drought, etc.
