Atmospheric radars, otherwise known as clear air radars, are advanced remote sensing system to investigate the atmospheric features through observation of the winds. They primarily depend on the back-scattered signals due to radio refractive index gradients associated with turbulent eddies to determine the velocity and range. Detecting the weak clear-air signal dictates the use of long coherent dwell times, low-noise system, low antenna side lobes, and careful attention to siting and potential interference [1]. In recent years, atmospheric radars have emerged as powerful tools for atmospheric research around the globe due to its capability of accurately measuring both the horizontal and vertical components of the wind in the vertical. The state-of-the-art VHF radar operating at 205 MHz at the Advanced Centre for Atmospheric Radar Research, Cochin University of Science and Technology (CUSAT) has played a pivotal role in exploring the physical processes occurring not only in the troposphere and lower stratosphere, but also in the earth's ionosphere reaching up to the F-region. In addition to estimating the 3-dimensional wind components ranging from 315 m to beyond 20 km above the earth's surface, it has the potential of detecting sub-metre scale field-aligned irregularities (FAI) in the E-and F-regions. The unexploited 200 MHz frequency band has the advantage of high signal to noise ratio, less cosmic noise, and good vertical coverage and in addition to high resolution especially in the lower troposphere. This paper unravels the potential of this particular Radar in exploring diverse atmospheric/ionospheric processes in the southern peninsular region.
