Radar interferometry and its application to changes in the Earth's surface
Reviews of Geophysics - Tập 36 Số 4 - Trang 441-500 - 1998
D. Massonnet, K. L. Feigl
Geophysical applications of radar interferometry to measure changes in the Earth's surface have exploded in the early 1990s. This new geodetic technique calculates the interference pattern caused by the difference in phase between two images acquired by a spaceborne synthetic aperture radar at two distinct times. The resulting interferogram is a contour map of the change in distance betwee...... hiện toàn bộ
Multiscale geophysical imaging of the critical zone
Reviews of Geophysics - Tập 53 Số 1 - Trang 1-26 - 2015
A. Parsekian, Kamini Singha, B. J. Minsley, W. Steven Holbrook, Lee Slater
AbstractDetails of Earth's shallow subsurface—a key component of the critical zone (CZ)—are largely obscured because making direct observations with sufficient density to capture natural characteristic spatial variability in physical properties is difficult. Yet this inaccessible region of the CZ is fundamental to processes that support ecosystems, society, and the...... hiện toàn bộ
Paleoceanographic events—Recognition, resolution, and reconsideration
Reviews of Geophysics - Tập 17 Số 7 - Trang 1474-1494 - 1979
Michael A. Arthur
Studies of the last 125 million years of oceanographic and climatic history have benefited greatly from the impetus provided by the Deep Sea Drilling Project. Knowledge of the sedimentary and paleontologic record of the major ocean basins, in conjunction with study of pelagic marine sections exposed on land, has permitted both the testing of old and the development of new hypotheses to exp...... hiện toàn bộ
On the North Atlantic Circulation
Reviews of Geophysics - Tập 31 Số 1 - Trang 29-49 - 1993
William J. Schmitz, Michael S. McCartney
A new, speculative, and, we hope, provocative summary of the North Atlantic circulation is described, including both horizontal currents (wind‐driven) and the primarily (thermohaline) meridional flows that involve the transformation of warm to cold water at high latitudes. Our picture is based on a synthesis of a variety of independent investigations that are contained in the literature as...... hiện toàn bộ
Global‐scale attribution of anthropogenic and natural dust sources and their emission rates based on MODIS Deep Blue aerosol products
Reviews of Geophysics - Tập 50 Số 3 - 2012
Paul Ginoux, Joseph M. Prospero, Thomas E. Gill, N. Christina Hsu, Ming Zhao
Our understanding of the global dust cycle is limited by a dearth of information about dust sources, especially small‐scale features which could account for a large fraction of global emissions. Here we present a global‐scale high‐resolution (0.1°) mapping of sources based on Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue estimates of dust optical depth in conjunction with...... hiện toàn bộ
ENVIRONMENTAL CHARACTERIZATION OF GLOBAL SOURCES OF ATMOSPHERIC SOIL DUST IDENTIFIED WITH THE NIMBUS 7 TOTAL OZONE MAPPING SPECTROMETER (TOMS) ABSORBING AEROSOL PRODUCT
Reviews of Geophysics - Tập 40 Số 1 - 2002
Joseph M. Prospero, Paul Ginoux, Omar Torres, Sharon E. Nicholson, Thomas E. Gill
We use the Total Ozone Mapping Spectrometer (TOMS) sensor on the Nimbus 7 satellite to map the global distribution of major atmospheric dust sources with the goal of identifying common environmental characteristics. The largest and most persistent sources are located in the Northern Hemisphere, mainly in a broad “dust belt” that extends from the west coast of North Africa, over the Middle ...... hiện toàn bộ
The Shuttle Radar Topography Mission
Reviews of Geophysics - Tập 45 Số 2 - 2007
T. G. Farr, P. A. Rosen, E.R. Caro, Robert E. Crippen, Riley Duren, S. Hensley, M. Kobrick, Mimi Paller, Ernesto Rodríguez, L. E. Roth, David Seal, S. Shaffer, J. Shimada, Jeffrey W. Umland, Marian Werner, M. E. Oskin, Douglas W. Burbank, Douglas Alsdorf
The Shuttle Radar Topography Mission produced the most complete, highest‐resolution digital elevation model of the Earth. The project was a joint endeavor of NASA, the National Geospatial‐Intelligence Agency, and the German and Italian Space Agencies and flew in February 2000. It used dual radar antennas to acquire interferometric radar data, processed to digital topographic data at 1 arc ...... hiện toàn bộ

What Is the Range of Soil Water Density? Critical Reviews With a Unified Model
Reviews of Geophysics - Tập 56 Số 3 - Trang 532-562 - 2018
Chao Zhang, Ning Lu
AbstractThe soil water density is defined as the ratio of soil water mass to soil water volume. It is a cornerstone in defining thermodynamic states of either saturated or unsaturated soils for quantifying water storage and movement in the subsurface and for mechanical stability of landscape. So far, it has been widely treated as identical to the free water density...... hiện toàn bộ
Atmospheric gravity waves generated in the high‐latitude ionosphere: A review
Reviews of Geophysics - Tập 20 Số 2 - Trang 293-315 - 1982
R. D. Hunsucker
A review of theoretical and observational results describing atmospheric gravity wave (AGW)/traveling ionospheric disturbance (TID) phenomena at high latitudes is presented. Some recent experimental studies of AGW's using the Chatanika incoherent scatter radar and other geophysical sensors are reported. Specifically, the following features are described in detail: (1) cause/effect relation...... hiện toàn bộ
