Professor Sivakumar Venkataraman

Dr Venkataraman's research focuses on atmospheric studies by using different insitu and satellite data-sets and is actively involved in various levels of teaching at the university.

He has published about 90 research articles and 4 book chapters, being a first author of more than 12 journal and 16 conference proceedings (average 8 publication/per year).

His research work includes (1) studies on middle atmospheric thermal structure and wave dynamics; (2) mesospheric temperature inversion; (3) studies on gravity waves, planetary waves, equatorial waves and etc., (4) stratospheric warming and planetary waves, (5) Aerosols and clouds, (6) general characteristics of the tropopause and its relation to the ozone concentration and the stratosphere-troposphere exchange, (7) remote sensing techniques and (8) various kinds of pollution measurements.

He is sat on the panel for various events: several NRF programmes, CSIR-NLC-Science and Education and Technology (SET) panel and the Technical committee member of CSIR Bi-annual conference (2008). He's been: the Vice-President and Council Member of South Africa Society for Atmosphere Science (SASAS) in 2007, on the Steering Committee member of South Africa – Space research (2010 - 2015), Session convener – ‘Remote Sensing of the atmosphere’ in Asia Oceania Geosciences Society (AOGS) (2008 - 2010) and different international/national Journal reviewer and Editor of the peer reviewed conference proceeding of SASAS (2010 - 2013).
