A new model of equatorial ionospheric scintillations in the Indian zone

The seasonal mean daily variations of 40, 140 and 360 MHz scintillations observed at Ootacamund, India during 1975-76 showed large differences with those computed from the model given by Fremouw et al (1977). A new model has been suggested taking into account the observations at equatorial regions; however, it could not be tested for different solar activity periods.
