Abstract
A doppler SODAR for measurement of wind characteristics at different heights has been installed at HASL, IGCAR, Kalpakkam and is in operation since January 1990. The technical specifications and basic aspects of SODAR, siting considerations and installation details are given. The report also discusses some observations regarding the site selection, installation and operation of SODARs. The basic theory of SODARs, some aspects of turbulence and dispersion in atmosphere and the various stability classification schemes areoutlined. Some details regarding land/sea-breeze circulations and inversions are also given.
