Book Description
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.

Book Description
Remote sensing is the acquisition of information of an object or phenomenon, by the use of either recording or real-time sensing device(s), that is not in physical or intimate contact with the object (such as by way of aircraft, spacecraft, satellite, buoy, or ship). In practice, remote sensing is the stand-off collection through the use of a variety of devices for gathering information on a given object or area. Human existence is dependent on our ability to understand, utilize, manage and maintain the environment we live in - Geoscience is the science that seeks to achieve these goals. This book is a collection of contributions from world-class scientists, engineers and educators engaged in the fields of geoscience and remote sensing.

Book Description
Past research has comprehensively assessed the capabilities of satellite sensors operating at microwave frequencies, both active (SAR, scatterometers) and passive (radiometers), for the remote sensing of Earth’s surface. Besides brightness temperature and backscattering coefficient, microwave indices, defined as a combination of data collected at different frequencies and polarizations, revealed a good sensitivity to hydrological cycle parameters such as surface soil moisture, vegetation water content, and snow depth and its water equivalent. The differences between microwave backscattering and emission at more frequencies and polarizations have been well established in relation to these parameters, enabling operational retrieval algorithms based on microwave indices to be developed. This Special Issue aims at providing an overview of microwave signal capabilities in estimating the main land parameters of the hydrological cycle, e.g., soil moisture, vegetation water content, and snow water equivalent, on both local and global scales, with a particular focus on the applications of microwave indices.
