Sreedharan Krishnakumari Satheesh (born 1970) is an Indian meteorologist and a professor at the Centre for Atmospheric and Oceanic Sciences of the Indian Institute of Science (IISc). He holds the chair of the Divecha Centre for Climate Change, a centre under the umbrella of the IISc for researches on climate variability, climate change and their impact on the environment. He is known for his studies on atmospheric aerosols and is an elected fellow of all the three major Indian science academies viz. Indian Academy of Sciences Indian National Science Academy and the National Academy of Sciences, India as well as The World Academy of Sciences. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to Earth, Atmosphere, Ocean and Planetary Sciences in 2009. He received the TWAS Prize of The World Academy of Sciences in 2011. In 2018, he received the Infosys Prize (in Physical Sciences category), one of the highest monetary awards in India that recognize excellence in science and research, for his work in the field of climate change.
Biography
S. K. Satheesh, born on 1 May 1970 in Thiruvananthapuram, the capital city of the south Indian state of Kerala to Sreedharan Nair and Krishnakumari Amma, did his graduate studies in science at the University of Kerala during 1987-90 and completed his master's degree from the same university in 1990. Enrolling at Kerala University, he did his doctoral studies at the Vikram Sarabhai Space Centre and after securing a PhD in 1997, he moved to the US for his post-doctoral work which was done at the Center for Clouds, Chemistry and Climate (C4) of Scripps Institution of Oceanography during 1998–2000. On his return to India, he joined the Centre for Atmospheric and Oceanic Sciences (CAOS) of the Indian Institute of Science as an assistant professor and has been serving IISc since then. During this period, he held the post of an associate professor from 2006 till he became a professor in 2011. He is the incumbent chairman of Divecha Center For Climate Change, a research wing of IISc for climate-related studies. He also served as a visiting scientist at the University of Bern and is an adjunct professor at the Aryabhatta Research Institute of Observational Sciences (ARIES) and the Indian Institute of Science Education and Research, Bhopal.
Satheesh is married to Deepshikha singh and the couple has one son, Satdeep Satheesh. The family lives in Bengaluru, India. His brother-in-law, Jaivir singh is an alumnus of IIT Kanpur and is currently a physics teacher at the Allen career institute.
Legacy
Satheesh is reported to have done extensive studies on atmospheric aerosols and his work is known to have widened our understanding of their impact on climate. He elucidated how the radiation balance of the Earth-atmosphere system and climate are influenced by the aerosols and one of his principal contributions is the hypothesis he suggested for the resolution of anomalous absorption paradox, a meteorological problem where cloud absorption measurements, at times, show inconsistency with the theoretical calculations. He has also experimentally shown how human-generated soot results in higher atmospheric temperatures by absorbing sunlight. Dust Absorption Efficiency (DAE) is another area of focus of his researches and he has studied the topic in relation to Afro-Asian regions and Indian deserts. His studies have been documented in several peer-reviewed articles; ResearchGate an online repository of scientific articles, has listed 171 of them. Two of his articles, Enhanced aerosol loading over Arabian Sea during pre-monsoon season: Natural or Anthropogenic? and Short wave versus long wave radiative forcing due to aerosol over Indian Ocean: Role of sea-surface winds, were included in the AGU Highlights by the American Geophysical Union during 2002–03 and his article, Radiative Effects of Natural Aerosols: A Review was listed as a Top 25 Hottest Article by ScienceDirect, an online scientific database.
Satheesh was a member of the first phase of Indian Ocean Experiment (INDOEX) conducted by an international team of scientists in 1999 and his article on the experiment warned of the rising aerosol levels in the atmosphere and its negative impact on climate. He also explained how monsoons were affected by the dust-containing aerosols of Arabian and Saharan regions and the sea-salt carrying aerosols of the Arabian sea. He has delivered several keynote or invited speeches on the topic.
