Big Data Google Earth Engine Sentinel-1 Glacier velocity field SAR off-set tracking San Rafael Glacier San Quintin Glacier
2018/5/11
The glaciers are a natural global resource and one of the principal climate change indicator at global and local scale, being influenced by temperature and snow precipitation changes. Among the parame...
ANALYZING THE VELOCITY OF VEGETATION PHENOLOGY OVER THE TIBETAN PLATEAU USING GIMMS NDVI3g DATA
Vegetation Phenology Velocity GIMMS NDVI Tibetan Plateau Climate Change
2018/5/17
Global environmental change is rapidly altering the dynamics of terrestrial vegetation, and phenology is a classic proxy to detect the response of vegetation to the changes. On the Tibetan Plateau, th...
oint Inversion of the 3D P Wave Velocity Structure of the Crust and Upper Mantle under the Southeastern Margin of the Tibetan Plateau Using Regional Earthquake and Teleseismic Data
3D P-wave velocity structure China seismic array detection Panxi region Chuan-Dian Block Daliangshan Block southeastern margin of Qinghai–Tibet Plateau
2018/4/10
The special seismic tectonic environment and frequent seismicity in the southeastern margin of the Qinghai–Tibet Plateau show that this area is an ideal location to study the present tectonic movement...
Using growth velocity to predict child mortality
anthropometry, longitudinal growth, mortality, prediction, WHO growth velocity standards
2018/11/28
Background: Growth assessment based on the WHO child growth velocity standards can potentially be used to predict adverse health outcomes. Nevertheless, there are very few studies on growth velocity t...
Strain pattern of the Southern Tyrrhenian slab from moment tensors of deep earthquakes:implications on the down-dip velocity
southern tyrrhenian seimin strain rate tensor down-dip velocity aseismic subduction
2015/9/28
Seismic strain is analysed along the slab face of the Southern Tyrrhenian subduction zone using focal mechanisms of deep earthquakes which occurred in the period 1960-1998. Results show that the slab ...
Low velocity and low electricalresistivity layers in the middle crust
seismic and electromagnetic studies Earth's crust Baltic and Ukranian shields
2015/9/14
Some Deep Seismic Sounding (DSS) revealed low velocity layers in the upper and middle crust of old platforms.The layers are often characterised by a lower electrical resistivity. It is not clear, howe...
Shear-wave velocity structure at Mt. Etna from inversion of Rayleigh-wave dispersion patterns (2 s < T < 20 s)
