geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. here we present the question: is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? the obtained answer is: yes. this investigation showed an agreeme...

the seismic anisotropy is a subject of interest for seismologists and geologists. the information of seismic anisotropy has significant role in geology interpretations (savage, 1999). in this study, we have investigated the upper crust anisotropy in bam area by means of shear wave splitting sg phase. we have selected more than three hundred aftershocks from iiees local temporary seismic network...

C points, that is, isolated points of circular polarization in transverse fields of varying polarization, are classified morphologically into three distinct types known as lemons, stars, and monstars. These morphologies are interpreted here according to two natural parameters associated with the singularity, namely, the anisotropy of the C point and the polarization azimuth on the anisotropy ax...

Abstract For several decades, shear-wave splitting (SWS) parameters (fast polarization orientations and splitting times) have been widely measured to reveal the orientation and strength of mantle anisotropy. One of the most popularly used techniques for obtaining station-averaged SWS parameters is the multiple-event stacking technique (MES). Results from previous studies suggest the splitting t...

Many researchers have used the birefringence of P‑to‑S converted waves from Moho discontinuity to constrain anisotropy Earth’s crust. However, this practice ignores substantial influence that has on initial amplitude wave, which adds splitting acquired during its propagation seismometer. We find large variations in Ps estimates with back-azimuth occur theoretically presence P‑wave anisotropy, n...

Constraints on upper crustal seismic anisotropy provide insight into the local stress orientation and structural fabric, but such constraints are scarce except in areas with dense recordings of local seismicity. We investigate directionally dependent Rayleigh wave ellipticity, or Rayleigh wave H/V (horizontal to vertical) amplitude ratios, between 8 and 20 s period across USArray to infer azimu...

While designed for ocean observation, scatterometer and radiometer data have proven very useful in a variety of cryosphere studies. Over large regions of Antarctica, ice sheet and bedrock topography and the snow deposition, drift, and erosional environment combine to produce roughness on various scales. Roughness ranges from broad, basin scale ice-sheet topography at 100 km wavelengths, to larg...
