Publikováno v: Annales Geophysicae, Vol 29, Pp 1209-1214 (2011)

The All-Sky interferometric meteor (SKYiMET) radar (MR) derived winds in the vicinity of the equatorial electrojet (EEJ) are discussed. As Thumba (8.5° N, 77° E; dip lat. 0.5° N) is under the EEJ belt, there has been some debate on the reliabil

Publikováno v: Annales Geophysicae, Vol 27, Pp 3853-3860 (2009)

The electrodynamic effects on the low-mid latitude ionospheric region have been investigated using GPS (global positioning system) data, ionosonde data and ΔH values, during the very large solar flare (X17.2/4B) of 28 October 2003. The results br

Autor: G. Manju, T. Kumar Pant, S. Ravindran, R. Sridharan

Publikováno v: Annales Geophysicae, Vol 27, Pp 2539-2544 (2009)

The present paper investigates the response of the equatorial and low latitude ionosphere over the Indian longitudes to the events on 29 October 2003 using ionosonde data at Trivandrum (8.5° N (0.5° N geomagnetic), 77° E) and SHAR (13.7° N (5.

Autor: G. Manju, C. V. Devasia, R. Sridharan

Publikováno v: Annales Geophysicae, Vol 25, Pp 855-861 (2007)

A study has been carried out on the occurrence of bottom side equatorial spread F (ESF) and its dependence on the polarity and magnitude of the thermospheric meridional wind just prior to ESF occurrence during summer, winter and equinox seasons of
