Abstract: To estimate the scintillations effects in troposphere for the Indian climate. Here the scintillations are the one of the most important prop-agation impairment at high frequencies(>10GHz) and low elevation angles(<10ᵒ) in the satellite communication systems particularly in adaptive link control systems design. India’s climate is tropical climate and vary with respect seasonally. Up to below 4 km range atmosphere is called tropical region. Scintillations defined by received signal passing through this tropical climate which has turbulent mixed up with rapid signal fluctuations because due to the solar radiation earth surface heated up and small scale variations occurred in refractive index of the medium[1].
Keywords: Temperature, Pressure, Humidity, Scintillations. Ka Band Frequency, Elevation Angle.
