Diurnal variation of tropospheric temperature at a tropical station

The vertical velocity in the troposphere-lower stratosphere region measured using MST radar has been utilized to evaluate the temperature profile in the region. The diurnal variation of the tropospheric temperature on one day in Augus...

Observational Properties of Harmonic EMIC Waves: Statistical Study

Abstract Electromagnetic ion cyclotron (EMIC) waves are discrete electromagnetic emissions separated by multiple ion gyrofrequencies. Harmonic EMIC waves are defined as waves with a strong electric or magnetic field (or both) at the harmoni...

Observations on Stratospheric-Mesospheric-Thermospheric temperatures using Indian MST radar and co-located LIDAR during Leonid Meteor Shower (LMS)

The temporal and height statistics of the occurrence of meteor trails during the Leonid meteor shower revealed the capability of the Indian MST radar to record large numbers of meteor trails. The distribution of radio meteor trails du...

Modulation of Mode‐Water Eddies on Upper Ocean Responses to Tropical Cyclones

Abstract The modulation of anticyclonic subsurface‐intensified mode‐water eddies (MWEs) on the oceanic physical and biological responses to tropical cyclones (TCs) is investigated using satellite measurements, in situ observations and numer...

Review of progress in passive seismic reflection exploration

Seismic exploration is a key method for the study of underground structures. Active seismic surveys can acquire high signal-to-noise ratio reflection data; however, the operation of active seismic surveys is complicated, and the exploration...

Two-Stage Framework for Efficient UAV-Based Wildfire Video Analysis With Adaptive Compression and Fire Source Detection

Uncrewed Aerial Vehicles (UAVs) have become increasingly important in disaster emergency response by facilitating aerial video analysis. Due to the limited computational resources available on UAVs, large models cannot be run efficiently fo...

Ice Nucleation Enhancement in Ambient Aerosols Under High‐Salinity Conditions: Insights From Cloud Chamber Experiments

Abstract Ice‐nucleating particles (INPs) play a role in mixed‐phase clouds, yet the processes controlling their properties remain poorly understood. Water‐soluble salts such as sodium chloride (NaCl) depress the freezing temperature of clou...

A Multi-Frequency Tomographic Inverse Scattering Using Beam Basis Functions

We present an overview of a beam-based approach to ultra-wide band (UWB) tomographic inverse scattering, where beam-waves are used for local data-processing and local imaging, as an alternative to the conventional plane-wave and Green’s fun...

Correlations Between Subduction of Linear Oceanic Features and Arc Volcanism Volume Around the Pacific Basin

Abstract Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions. In this study, we address a fundamental question, namely, how do subduct...

The solar wind plasma density control of night-time auroral particle precipitation

DMSP F6 and F7 spacecraft observations of the average electron and ion energy, and energy fluxes in different night-time precipitation regions for the whole of 1986 were used to examine the precipitation features associated with solar win...

The Beginning of a Wilson Cycle in an Accretionary Orogen: The Mongol–Okhotsk Ocean Opened Assisted by a Devonian Mantle Plume

Abstract The opening of oceans within accretionary orogens is important for understanding the Wilson cycle. The Mongol–Okhotsk Ocean (MOO) began opening within the early Paleozoic accretionary collage of the Central Asian Orogenic Belt (CAO...

Geophysics for the mineral exploration geoscientist

Providing a balance between principles and practice, this state-of-the-art overview of geophysical methods takes readers from the basic physical phenomena, through the acquisition and processing of data, to the creation of geological models...

Encyclopedic Dictionary of Applied Geophysics

The fourth edition of SEG's best seller is a valuable, comprehensive reference that is a must for every geophysicist, geologist, explorationist, engineer, energy adviser, economist, editor, and student involved in the field. Hundreds of ter...

Fractals and Chaos in Geology and Geophysics

This book introduces the fundamental concepts of fractal geometry and chaotic dynamics. These concepts are then related to a variety of geological and geophysical problems, illustrating just what chaos theory and fractals really tell us and...

Glacier Geophysics

From physical measurements on glaciers and experimental studies of ice properties a framework of concept and theory is being built which bids fair to place glaciers among the more quantitatively understandable phenomena in the earth science...

The New Geophysics

Abstract New Geophysics of critically microcracked rock is a new understanding of fluid‐rock deformation that matches much of the behaviour of in situ rock observed throughout the Earth's crust and uppermost mantle. The behaviour of rock in...

Geophysics as a science

Abstract "Geophysics" means "Physics of the Earth." While in physics one tries to eliminate the effects of the gravitational, electric, and magnetic fields of the earth, in geophysics these fields, their properties and effects, and the stru...

Geophysics in Engineering Investigations

The Construction Directorate of the DTI supports the programme of innovation and research to improve the construction industry's performance and to promote more sustainable construction. Its main aims are to improve quality and value for mo...

Green’s functions for geophysics: a review

The Green's function (GF) method, which makes use of GFs, is an important and elegant tool for solving a given boundary-value problem for the differential equation from a real engineering or physical field. Under a concentrated source, the ...
