Fine scale structure and turbulence parameters in the equatorial middle atmosphere
Abstract
Two rockets carrying identical spherical probe payloads were launched from Thumba, India to measure positive ion density of the mesosphere and lower thermosphere over an equatorial location. Data obtained show the presence of strong irregularities in the ion density. From the measured positive ion current, the spectra of the spatial density fluctuation, turbulent velocity, energy dissipation rate, and eddy diffusion coefficients have been derived in the altitude range of 70-100 km. The results are found to be different from those at middle and high latitudes.
