Abstract: 
First results from a unique coordinated campaign involving the Multi wavelength Daytime Photometer and 
the VHF radar from a dip equatorial station, Thumba , Trivandrum, India, concerning the daytime 
mesopause temperature variabilities and its possible consequences on the phenomenon of Equatorial 
Electrojet and also the effects of the variations in the dynamo electric fields on the thermospheric OI 
630 nm airglow through the electrodynamical coupling are presented.   These results highlight the
complex coupled nature of the equatorial atmospheric system, and the significant control of the neutral 
atmospheric parameters and their variabilities on the equatorial ionospheric phenomena.
