Passive Microwave Remote Sensing Of Land Atmosphere Interactions

No detailed description available for "Passive Microwave Remote Sensing of Land-Atmosphere Interactions".

Recent advances in theory and observations using passive microwave remote sensing have hightlighted the potential of spaceborne sensors for contributing to the required land surface measurements of soils, vegetation, snow cover and precipitation. Furthermore, the spatial resolution of passive microwave observations matches the special scales of large-scale models of land-atmosphere interactions both for data assimilation and validation. In order to stimulate and focus this research a workshop, sponsored by ESA and NASA, was organized to review the state-of-the-art in microwave radiometry related to land applications and to exchange ideas leading into new directions for future research. This volume contains the refereed papers from the aforementioned ESA/NASA workshop, which are arranged by topic, as well as the (edited) working group reports.

We will show in this monograph some possibilities of using the potential of satellite passive microwave radiometric methods for the analysis of variations of heat and dynamic processes in the ocean–atmosphere interface in a wide range of time scales – from mesometeorogical (hours, daily) to seasonal (month) and multiyear (climatic) ones. The most essential mechanisms of intercommunication of natural microwave radiation of the system ocean–atmosphere (SOA) with the vertical turbulence fluxes of sensible, latent heat, as well as the momentum at the boundary of the SOA are studied. We will consider the turbulence heat fluxes as the factors generated by the c- otic movements in the atmosphere, when every small individual part of air is moved irregularly. Here, one can observe a transfer of the energy from large-scale to sma- scales; the average distance between the air particles is increased with a time. Also, the potential of remote sensing the characteristics of heat and water adv- tion and their accumulation in the atmosphere boundary layer are demonstrated. In these studies, we mean mainly the middle and high latitudes of the North Atlantic, which are forming the weather conditions and climatic trends over Europe and European territories of the Russia.

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.

This book covers the fundamentals of satellite microwave instrument calibration, remote sensing sciences and algorithms, as well as the applications of the satellite microwave observations in weather and climate research.
