Height gradient of F region vertical drift in the evening equatorial ionosphere

Sastri, J. H; Varma, V. K. M; Nayar, S. R. P (American Geophysical Union, 1995-10)

Simultaneous measurements of F-region vertical drift are made in the evening hours (1700-2100 IST) at Trivandrum (dip 0.6°N) and Kodaikanal (dip 4°N) on fifteen days during December 1993- January 1994 using the HF phase ...
Response of equatorial F layer vertical drift in the dusk sector to the change in the radiative output of the Sun in 1992

Sastri, J. H (American Geophysical Union, 1995-06)

A study is made of the effect of the rapid and large decline in the solar radiative output that occurred from March through May 1992 on the postsunset maximum in F layer vertical drift Vzp over Kodaikanal (dip 3°N). Between ...
Response of equatorial-low latitude ionosphere to sudden expansion of magnetosphere

Sastri, J. H; Huang, Y. N; Shibata, T; Okuzawa, T (American Geophysical Union, 1995-10)

The response of the equatorial-low latitude nightside ionosphere to the geomagnetic negative sudden impulse(si-) on March 15, 1993 is studied using recordings of Doppler velocity of ionospheric echoes at vertical incidence ...
