Available in PDF, EPUB and Kindle. Book excerpt: Global rainfall over land and ocean is estimated using measurements of upwelling microwaves by a satellite passive microwave radiometer. Radiative transfer calculations through a cloud model are used to parameterize an inversion technique for retrieving rain rates from brightness temperatures measured by the Special Sensor Microwave Imager (SSM/I). The rainfall retrieval technique is based on the interaction between multi-spectral microwave radiances and millimeter sized liquid and frozen hydrometeors distributed in the satellite's field of view. The rain rate algorithm is sensitive to both hydrometeor emission and scattering while being relatively insensitive to extraneous atmospheric and surface effects. Separate formulations are used over ocean and land to account for different background microwave characteristics and the algorithm corrects for inhomogeneous distributions of rain rates within the satellite's field of view. Estimates of instantaneous and climate scale rainfall are validated through comparisons with modeled clouds, surface radars, rain gauges and alternative satellite estimates. The accuracy of the rainfall estimates is determined from a combination of validation comparisons, theoretical sampling error calculations, and modeled sensitivity to variations in atmospheric and surface radiative properties. An error budget is constructed for both instantaneous rain rates and climate scale global estimates. At a one degree resolution, the root mean square errors in instantaneous rain rate estimates are 13% over ocean and 20% over land. The root mean square errors in global rainfall totals over a four month period are found to be 46% over ocean and 63% over land. Global rainfall totals are computed on a monthly scale for a three year period from 1987 to 1990. The time series is analyzed for climate scale rainfall distribution and variability.

This book was released on 2023-06-14 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a selection of refereed papers presented at the 6 Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment held in Florence, Italy on March 15-18, 1999. Over the last two decades, passive microwave remote sensing has made considerable progress, and has achieved significant results in the study of the Earth's surface and atmosphere. Many years of observations with ground-based and satellite-borne sensors have made an important contribution to improving our knowledge of many geophysical processes of the Earth's environment and of global changes. The evolution in microwave radiometers aboard satellites has increased steadily over recent years. At the same time, many investigations have been carried out both to improve the algorithms for the retrieval of geophysical parameters and to develop new technologies. The book is divided into four main sections: three of these are devoted to the observation of the Earth's surface and atmosphere, and the fourth, to future missions and new technologies. The first section deals with the study of sea and land surfaces, and reports recent advances in remote sensing of ocean wind, sea ice, soil moisture and vegetation biomass, including electromagnetic modelling and the assimilation of radiometric data in models of land surface processes. The following two sections are devoted to the measurement of atmospheric quantities which are of fundamental importance in climatology and meteorology, and, since they influence radio-wave propagation, they also impact on several other fields, including geodesy, navigational satellite and radioastronomy. The last section presents an overview of new technologies and plans for future missions.

Download or read book Remote Sensing of Precipitation written by Silas Michaelides and published by MDPI. This book was released on 2019-07-23 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precipitation is a well-recognized pillar in global water and energy balances. An accurate and timely understanding of its characteristics at the global, regional, and local scales is indispensable for a clearer understanding of the mechanisms underlying the Earth’s atmosphere–ocean complex system. Precipitation is one of the elements that is documented to be greatly affected by climate change. In its various forms, precipitation comprises a primary source of freshwater, which is vital for the sustainability of almost all human activities. Its socio-economic significance is fundamental in managing this natural resource effectively, in applications ranging from irrigation to industrial and household usage. Remote sensing of precipitation is pursued through a broad spectrum of continuously enriched and upgraded instrumentation, embracing sensors which can be ground-based (e.g., weather radars), satellite-borne (e.g., passive or active space-borne sensors), underwater (e.g., hydrophones), aerial, or ship-borne.

This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The power of microwave remote sensing for studying the oceans of the world was demonstrated conclusively by the SEASAT mission in 1978. Since then, no further satellite-flown instruments have been available to provide further data of this type. However, the proposed launch of ESA's ERS-1 satellite will lead to a new set of active microwave instruments being flown in space in 1990. Even though similar data has been obtained from aircraft-flown instruments SAR, scatterometers, altimeters etc. - a great deal of activity has been taking place to develop the necessary expertise in handling and analysing such data when it comes on-stream from ERS-1 and from subsequent satellites. It was against this background that the scientific Affairs Division of NATO again agreed to sponsor an ASI in Dundee in 1988. Its purpose was to review existing knowledge of the extraction of marine and atmospheric geophysical parameters from satellite-gathered microwave data and to enable scientists to prepare themselves and their computing systems to utilise the new data when it becomes available. The importance of the data is largely as input parameters to assist in the fitting of boundary conditions in large computer models. The course was concerned more with the non-imaging instruments, that is with passive radiometers, altimeters and scatterometers, than with the (imaging) synthetic aperture radar.

Available in PDF, EPUB and Kindle. Book excerpt: Passive Microwave Remote Sensing of Oceans Igor V. Cherny and Victor Yu. Raizer In Passive Microwave Remote Sensing of Oceans, the detailed results of more than 20 years of experimental and theoretical investigations in the field of ocean remote sensing, utilising microwave radiometric techniques and multi-frequency aerospace instruments, are presented. Experimental results presented in this book to some extent contradict the traditional view that microwave radiometry and, in particular, millimetre-wave frequencies are not useful for remote sensing of oceans. The authors show that studies of the ocean and atmosphere as a coupled system, and of processes occurring at the ocean surface and in deep water, can be reliably evolved using compact passive radiometric sensors. They further demonstrate that for studies of global, large-scale and local processes in the ocean-atmosphere system, only the combination of microwave and optical techniques will reveal the spatial structure and dynamics of the ocean surface at scales from centimetres to several hundred metres. The text first introduces ocean surface phenomena, discussing the ocean-atmosphere interface, the classification of surface waves, the generation and statistics of wind waves, and wave-breaking and foaming processes. The microwave emission characteristics of the ocean surface are then described, and the influence of wind waves, bubble-foam-spray coverage, oil spills and sea ice are discussed. The instruments and methods used for passive microwave remote sensing of the oceans from both aircraft and from satellites are reviewed. Microwave observations of processes in the ocean-atmosphere system are then described in detail, incorporating a new approach for microwave diagnostics of deep-ocean processes. Examples presented include the Rossby soliton, frontal zone in the Kurosio region, influence of brief showers on the subsurface layer, and interaction of tropical cyclones with the ocean during their origin and subsequent trajectories over the ocean surface. Readership: Undergraduate and postgraduate students studying remote sensing, marine science, oceanography, geography, geophysics, meteorology, climatology, atmospheric physics and environmental science. Professional oceanographers and those interested in oceanographic remote sensing processes and their applications, marine scientists and engineers, environmental scientists, and those studying the ocean-atmosphere system.

Available in PDF, EPUB and Kindle. Book excerpt: As already noted, rainfall retrievals using data from MWIs such as TMI are superior to those using data from MWSs such as AMSU. Figure 5 compares GSMaP_TMI-retrieved and GSMaP_AMSU-retrieved rain rates at 0.1 × 0.1 with rain rates estimated from the groundbased radar at Kwajalein Island, Republic of the Marshall Islands (Wolff et al. 2005). Although it is hard to tell whether the pattern of the GSMaP_TMI rain rates is biased with respect to the Kwajalein radar estimated-rain rates, the GSMaP_AMSU algorithm clearly overestimates (underestimates) rainfall at light (heavy) rain rates. While the TMI scan at a.

Download or read book NOAA s Role in Space Based Global Precipitation Estimation and Application written by National Research Council and published by National Academies Press. This book was released on 2007-03-13 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Oceanic and Atmospheric Administration (NOAA) uses precipitation data in many applications including hurricane forecasting. Currently, NOAA uses data collected from the Tropical Rainfall Measuring Mission (TRMM) satellite that was launched in 1997 by NASA in cooperation with the Japan Aerospace Exploration Agency. NASA is now making plans to launch the Global Precipitation Measurement (GPM) mission in 2013 to succeed TRMM, which was originally intended as a 3 to 5 year mission but has enough fuel to orbit until 2012. The GPM mission consists of a "core" research satellite flying with other "constellation" satellites to provide global precipitation data products at three-hour intervals. This book is the second in a 2-part series from the National Research Council on the future of rainfall measuring missions. The book recommends that NOAA begin its GPM mission preparations as soon as possible and that NOAA develop a strategic plan for the mission using TRMM experience as a guide. The first book in the series, Assessment of the Benefits of Extending the Tropical Rainfall Measuring Mission (December 2004), recommended that the TRMM mission be extended as long as possible because of the quality, uniqueness, and many uses of its data. NASA has officially extended the TRMM mission until 2009.
