Who is prof Manikandan Mathur, the IIT-Madras scientist who helped ISRO and NASA optimise NISAR satellite?
Agencies Unlike earlier Earth observation satellites that struggled with coastal imaging and cloud interference, NISAR will offer high-resolution imagery—down to tens of metres—and revisit the same location every 12 days. An IIT-Madras professor has played a pivotal role in shaping how NISAR, the Indo-US Earth observation satellite launched on Wednesday, will track and analyse coastal regions. Prof Manikandan Mathur, from the Geophysical Flows Lab at the Centre of Excellence in the Department of Aerospace Engineering, collaborated with ISRO and NASA to fine-tune the satellite's operational strategy. He provided key input on optimal imaging frequency, timing, and selection of coastal zones for monitoring. Prof Mathur stressed the importance of closely observing the north Indian Ocean to better understand coastal processes and their links to weather systems and pollution dispersal. His team plans to use NISAR's data to study interactions between river discharge and ocean waters in the Bay of Bengal, the dynamics of internal gravity waves along India's coasts, and how these phenomena influence regional weather patterns, including extreme rainfall and flooding. Unlike earlier Earth observation satellites that struggled with coastal imaging and cloud interference, NISAR will offer high-resolution imagery—down to tens of metres—and revisit the same location every 12 days. 'NISAR addresses both major limitations of past missions and will also capture fine-scale Earth surface features never observed before,' Prof Mathur was quoted as saying by the Times of India. He called the mission a "unique collaboration" that combines the strengths of two frequency bands contributed by ISRO and NASA. Prof Mathur also highlighted the potential of open access to NISAR data to significantly advance Indian research, especially for young scientists. 'Awareness of what satellite imaging can achieve is set to grow within the Indian scientific community,' he noted. He added that the data would also unlock new possibilities for experts in machine learning and data science to contribute to socially impactful research.

How an IIT-Madras professor has helped Isro, Nasa fine-tune Nisar's operational settings
CHENNAI: An IIT-Madras professor has contributed to shaping how Nisar, the Indo-US satellite launched on Wednesday, will observe coastal regions. Prof Manikandan Mathur of the Geophysical Flows Lab, Centre of Excellence, Department of Aerospace Engineering, IIT-Madras, helped and fine-tune the satellite's operational settings by advising on when, how often, and which coastal regions should be imaged. Tired of too many ads? go ad free now He highlighted the need for high-resolution observations of the north Indian Ocean to improve understanding of coastal processes and their role in weather modelling and pollutant transport. Prof Mathur and his team plan to use Nisar data to study how river water mixes with the ocean in the Bay of Bengal, internal gravity waves in the coastal Indian Ocean, and how these processes influence regional weather and high-impact events like intense rainfall and flooding in the Indian subcontinent. Unlike earlier Earth observation satellites, which have either been poor in imaging coastal regions or perform poorly in cloudy weather, Nisar will provide images at resolutions of a few tens of metres and revisit the same location every 12 days. 'Nisar will overcome both these drawbacks, in addition to its imaging of very fine scale features on the Earth's surface that we have never seen before,' he said. 'This is a unique collaboration between Isro and Nasa, combining the best of the capabilities of two different frequency bands,' he added. Prof Mathur added that the open access to Nisar data would be game-changing for the Indian scientific community, especially young researchers. 'The general awareness amongst the Indian scientific community about what is possible using satellite imaging is going to increase significantly,' he said. It would also open up a very exciting, societally relevant area of application for the machine learning and data science community, he added.
