Solar flux dependence of coherence scales in scintillation patterns produced by ESF irregularities [PDF]
Annales Geophysicae, 2005 The coherence scale length, defined as the 50% decorrelation scale length along the magnetic east-west direction, in the ground scintillation pattern obtained at a dip equatorial location, due to scattering of VHF radio waves by equatorial spread F ...

Seasonal variabilities of low-latitude mesospheric winds [PDF]
Annales Geophysicae, 1998 Observations of mesospheric winds over a period of four years with the partial reflection radar at Tirunelveli (8.7°N, 77.8°E), India, are presented in this study. The emphasis is on describing seasonal variabilities in mean zonal and meridional winds

Geomagnetic Polarity Timescale [PDF]
, 2001 Dating and time control are essential geoscience, because they allow us to rock sequences from different environments of deposition. Most importantly, accurate time control allows us to calculate rates of change, which is necessary for understanding underlying processes and mechanisms.

Low-latitude geomagnetic signatures during major solar energetic particle events of solar cycle-23 [PDF]
Annales Geophysicae, 2006 The frequency of occurrence of disruptive transient processes in the Sun is enhanced during the high solar activity periods. Solar cycle-23 evidenced major geomagnetic storm events and intense solar energetic particle (SEP) events.

Annual Review of Earth and Planetary Sciences, 2012 Observations of Earth's magnetic field from space began more than 50 years ago. A continuous monitoring of the field using low Earth orbit (LEO) satellites, however, started only in 1999, and three satellites have taken high-precision measurements of the geomagnetic field during the past decade.

First analysis of GLE 72 event on 10 September 2017: Spectral and anisotropy characteristics
, 2018 Using neutron monitor and space-borne data we performed an analysis of the second ground level enhancement of solar cycle 24, namely the event of 10 September 2017 (GLE 72) and derive the spectral and angular characteristics of GLE particles.
