Book excerpt: Fully polarimetric scattering of electromagnetic waves from snow and sea ice is studied with a layered random medium model and applied to interpret experimental data obtained under laboratory controlled conditions. The snow layer is modeled as an isotropic random medium. The sea ice is described as an anisotropic random medium due to the elongated form of brine inclusions. The underlying sea water is considered as a homogeneous half-space. The scattering effects of both random medium are described by three dimensional correlation functions with variances and correlation lengths corresponding to the fluctuation strengths and the physical geometry of the inhomogeneities, respectively. The strong fluctuation theory is used to calculate the effective permittivities of the random media. The distorted Born approximation is then applied to obtain the covariance matrix which describes th full polarimetric scattering properties of the remotely sensed media. (mm).

Download or read book Remote Sensing of Sea Ice with Wideband Microwave Radiometry written by Oguz Demir and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea ice is one of the most important components of Earth’s cryosphere that regulates heat flow between the ocean and atmosphere, impacts water cycles and oceanic currents due to salt transport during the melt and freeze seasons, provides a natural habitat for many life forms, and affects global transportation. Remote sensing of sea ice has become more important than ever given the substantial reduction in sea ice extent in the Arctic in recent decades. A major advantage of remote sensing for sea ice studies is the continuous monitoring available from space that eliminates the need for expensive and difficult in-situ measurements. Although satellite-borne passive microwave radiometer observations of sea ice have been performed since the 1970s, significant challenges remain. Radiometer measurements at frequencies greater than approximately 19 GHz can detect sea ice concentration and extent but are impacted by clouds. L-band radiometers operating at 1.4 GHz have been shown to successfully estimate sea ice thicknesses up to ~1.5 m; however, thickness sensing performance is limited by the penetration depth in sea ice at this signal frequency. Radiometers operating at lower frequencies have not been used on satellites to date due to the strong man-made radio frequency interference (RFI) present at frequencies less than 1.4 GHz. The Ultra-Wideband Software-defined Microwave Radiometer (UWBRAD) was developed at The Ohio State University to observe thermal emissions in the presence of RFI. The instrument performs RFI detection and mitigation algorithms at multiple frequency channels from 0.5 – 2.0 GHz. As a result, UWBRAD is capable of retrieving sea ice thickness for ice thicknesses greater than 1.5 m due to its lower operating frequencies. In addition, the measurement of sea ice thermal emissions over the 0.5-2 GHz spectrum reveals additional information on ice characteristics and can allow the simultaneous retrieval of sea ice thickness and salinity. This dissertation examines the remote sensing of sea ice through wideband microwave radiometry. Sea ice thermal emissions are modeled for UWBRAD’s 0.5-2 GHz frequency spectrum and compared with measurements from validation campaigns. A retrieval process is also described to characterize ice thickness and salinity. Results from the two successful campaigns in which the instrument was operated in Greenland and in the Arctic are demonstrated. In addition, wideband retrieval performance is further investigated to explore the effect of available ancillary data, and Arctic scale retrieval simulations are described that provide additional insights to guide future wideband radiometer remote sensing missions.
Download or read book Springer Handbook of Atmospheric Measurements written by Thomas Foken and published by Springer Nature. This book was released on 2021-11-09 with total page 1761 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical handbook provides a clearly structured, concise and comprehensive account of the huge variety of atmospheric and related measurements relevant to meteorologists and for the purpose of weather forecasting and climate research, but also to the practitioner in the wider field of environmental physics and ecology. The Springer Handbook of Atmospheric Measurements is divided into six parts: The first part offers instructive descriptions of the basics of atmospheric measurements and the multitude of their influencing factors, fundamentals of quality control and standardization, as well as equations and tables of atmospheric, water, and soil quantities. The subsequent parts present classical in-situ measurements as well as remote sensing techniques from both ground-based as well as airborn or satellite-based methods. The next part focusses on complex measurements and methods that integrate different techniques to establish more holistic data. Brief discussions of measurements in soils and water, at plants, in urban and rural environments and for renewable energies demonstrate the potential of such applications. The final part provides an overview of atmospheric and ecological networks. Written by distinguished experts from academia and industry, each of the 64 chapters provides in-depth discussions of the available devices with their specifications, aspects of quality control, maintenance as well as their potential for the future. A large number of thoroughly compiled tables of physical quantities, sensors and system characteristics make this handbook a unique, universal and useful reference for the practitioner and absolutely essential for researchers, students, and technicians.

Available in PDF, EPUB and Kindle. Book excerpt: Our progress over the last year has been along several dimensions: 1. Exploration and understanding of Earth Observatory System (EOS) mission with available data from NASA. 2. Comprehensive review of state of the art techniques and uncovering of limitations to be investigated (e.g. computational, algorithmic ...). and 3. Preliminary development of resolution enhancement algorithms. With the advent of well-collaborated satellite microwave radiometers, it is now possible to obtain long time series of geophysical parameters that are important for studying the global hydrologic cycle and earth radiation budget. Over the world's ocean, these radiometers simultaneously measure profiles of air temperature and the three phases of atmospheric water (vapor, liquid, and ice). In addition, surface parameters such as the near surface wind speed, the sea surface temperature, and the sea ice type and concentration can be retrieved. The special sensor microwaves imager SSM/I has wide application in atmospheric remote sensing over the ocean and provide essential inputs to numerical weather-prediction models. SSM/I data has also been used for land and ice studies, including snow cover classification measurements of soil and plant moisture contents, atmospheric moisture over land, land surface temperature and mapping polar ice. The brightness temperature observed by SSM/I is function of the effective brightness temperature of the earth's surface and the emission scattering and attenuation of the atmosphere. Advanced Microwave Scanning Radiometer (AMSR) is a new instrument that will measure the earth radiation over the spectral range from 7 to 90 GHz. Over the world's ocean, it will be possible to retrieve the four important geographical parameters SST, wind speed, vertically integrated water vapor, vertically integrated cloud liquid water L.
