The people behind
Aerosol Tattvam
A lifetime exploring the atmosphere.
Two generations bringing its stories to life.
Aerosol Tattvam is a father-son endeavour, shaped by decades of atmospheric research and a shared desire to make scientific knowledge accessible beyond the laboratory.
The scientific vision comes from Prof. Achuthan Jayaraman. The digital experience is built and maintained by his son, Siddharth Jayaraman. Together, they bring research, experience and technology into a space for anyone curious about the atmosphere.
Prof. Achuthan
Jayaraman
Scientific Editor | Atmospheric Scientist | Former Director, National Atmospheric Research Laboratory
For more than four decades, Prof. Achuthan Jayaraman has explored the Earth's atmosphere, particularly the tiny suspended particles known as aerosols and their influence on atmospheric radiation and climate.
His research has taken him from the upper atmosphere, using rocket- and balloon-borne instruments to investigate aerosol properties, to the Indian Ocean, where ship-based experiments helped reveal how aerosols affect the Earth's radiation balance. His work includes contributions to the development of India's first Nd:YAG backscatter lidar for atmospheric aerosol measurements and to major international research initiatives, including the Indian Ocean Experiment (INDOEX).
Beginning his scientific career at the Physical Research Laboratory (PRL), Ahmedabad, he went on to serve as Director of the National Atmospheric Research Laboratory (NARL), Gadanki, from 2007 to 2017. He has also contributed to international scientific assessments and collaborations, including as a Lead Author of the Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report and as Vice-President of the Committee on Space Research (COSPAR).
His contributions have been recognised through several scientific honours, including election as a Fellow of the Indian Academy of Sciences and the ISRO Merit and Performance Excellence Awards.
At Aerosol Tattvam, he brings this experience to a different audience. As Scientific Editor, he shapes the scientific direction of the publication, drawing on his research, field experience and personal scientific archives to explore the atmosphere with clarity, curiosity and depth.

Website Development & Stewardship
Behind the website is another part of the story.
Siddharth Jayaraman, Prof. Jayaraman's son, is responsible for designing, developing, hosting and maintaining Aerosol Tattvam.
His contribution is to give the science a digital home: bringing together research, historical materials and scientific stories in a form that readers can discover, explore and revisit.
What began as an opportunity to share his father's knowledge has become a collaboration between generations, combining a lifetime of scientific experience with the technology to bring it to a wider audience.
