Joint inversion of Rayleigh wave phase velocity and ellipticity using...
Rayleigh wave ellipticity, or H/V ratio, observed on the surface is particularly sensitive to shallow earth structure. In this study, we jointly invert measurements of Rayleigh wave H/V ratio and phase...
View ArticleHow moderate sea states can generate loud seismic noise in the deep ocean
The location of oceanic sources of the micrometric ground displacement recorded at land stations in the 0.1–0.3 Hz frequency band (“double frequency microseisms”) is still poorly known. Here we use one...
View ArticleCo-variation of temperature and precipitation in CMIP5 models and satellite...
Current variability of precipitation (P) and its response to surface temperature (T) are analysed using coupled (CMIP5) and atmosphere-only (AMIP5) climate model simulations and compared with...
View ArticleOn the space-time distribution of major explosive volcanic eruptions on Earth
Explosive volcanic activity on Earth is typically discontinuous in space and time. The occurrence of spatial/temporal eruption clusters due to mutual cause-and-effect relationships or external triggers...
View ArticleDust transport from non-East Asian sources to the North Pacific
It is generally thought that East Asia dominates the supply of eolian dust to the North Pacific. Here we show the first data-based evidence of dust primarily from non-East Asian sources even during...
View ArticleJoint analysis of displacement time series retrieved from SAR phase and...
We study the impact of jointly analyzing the phase and amplitude information of a SAR dataset on the interpretation of the surface displacement over time in areas characterized by large dynamics. In...
View ArticleA method for disentangling El Niño–mean state interaction
The amplitude of the El Niño-Southern Oscillation (ENSO) is known to fluctuate in long records derived from observations and general circulation models (GCMs), even when driven by constant external...
View ArticleA physical mechanism for North Atlantic SST influence on the Indian summer...
A link between the Atlantic Multidecadal Oscillation (AMO) and multidecadal variability of the Indian summer monsoon rainfall is unraveled and a long sought physical mechanism linking Atlantic climate...
View ArticleCoupling between Greenland blocking and the North Atlantic Oscillation pattern
Through the adoption of a bidimensional blocking index based on geopotential height, it is shown that the blocking frequency over Greenland is not only a key element in describing the North Atlantic...
View ArticleHow is the ocean filled?
The ocean surface rapidly exchanges heat, freshwater, and gases with the atmosphere, but once water sinks into the ocean interior, the inherited properties of seawater are closely conserved. Previous...
View ArticleAcoustic emission monitoring of hydraulic fracturing laboratory experiment...
Carbon dioxide (CO2) is often used for enhanced oil recovery in depleted petroleum reservoirs, and its behavior in rock is also of interest in CO2 capture and storage projects. CO2 usually becomes...
View ArticleWeighing the ocean: Using a single mooring to measure changes in the mass of...
Combining ocean and earth models, we show that there is a region in the central Pacific ocean where ocean bottom pressure is a direct measure of interannual changes in ocean mass, with a noise level...
View ArticleSeasonal inflow of warm water onto the southern Weddell Sea continental...
To capture the austral summer to winter transition in water mass properties over the southern Weddell Sea continental shelf and slope region, 19 Weddell seals were tagged with miniaturized...
View ArticleOn the interpretation of constrained climate model ensembles
An ensemble of models can be interpreted in two ways. The first treats each model as an approximation of the true system with some random error. Alternatively, the true system can be interpreted as a...
View ArticleIce loss from the Southern Patagonian Ice Field, South America, between 2000...
A time-series composed of 156 ASTER derived Digital Elevation Models (DEMs) and a radar-penetration-bias corrected version of the Shuttle Radar Topography Mission (SRTM) DEM is used to derive ice...
View ArticleSubduction of oceanic asthenosphere: Evidence from sub-slab seismic anisotropy
The oceanic asthenosphere is characterized as a low viscosity channel down to 200–300 km depth separating the cold lithosphere from above, and it is intimately linked to a layer of low seismic velocity...
View ArticleRadiative forcing by light absorbing impurities in snow from MODIS surface...
The episodic deposition of dust and carbonaceous particles to snow decreases snow surface albedo and enhances absorption of solar radiation, leading to accelerated snowmelt, negative glacier mass...
View ArticleSecular temperature trends for the southern Rocky Mountains over the last...
Pre-instrumental surface temperature variability in the Southwestern United States has traditionally been reconstructed using variations in the annual ring widths of high altitude trees that live near...
View ArticleSatellite-based estimates of reduced CO and CO2 emissions due to traffic...
During the 2008 Olympics, the Chinese government made a significant effort to improve air quality in Beijing, including restrictions on traffic. Here we estimate the reductions in carbon monoxide (CO)...
View ArticleHow large are projected 21st century storm track changes?
Projected changes in the extra-tropical wintertime storm tracks are investigated using the multi-model ensembles from both the third and fifth phases of the World Climate Research Programme's Coupled...
