Lower Atmospheric Wind Profile Studies and Validation of VHF Doppler Radar of University of Calcutta

An active phased-array VHF Doppler radar operated at 53 MHz is being established by University of Calcutta, Kolkata, at Ionosphere Field Station (latitude: 22.93 °N, longitude: 88.50 °E), Haringhata of the University near the transition between tropical-to-sub-tropical regions. A Pilot Array is presently operational. When completed, the main radar will be a unique facility to study the lower atmospheric dynamics over the eastern and north-eastern parts of India. Initial results of three components of wind profiles, i.e. zonal wind (u), meridional wind (v), and vertical wind (w) and their validation through balloon-borne GPS Radiosonde measurements made during July 2019 have been presented in this paper.
