He demonstrated aerosol indirect effects showing the importance of aerosol-cloud feedback via cloud condensation nuclei during summer monsoon over India for the first time.

Kanpur supersite successfully operated a state of art eddy co-variance flux tower, ceilometer, microwave radiometer and launched radiosondes which provided a wealth of information on near surface energy balance, cloud properties and atmosphere thermodynamics which has helped better prediction of monsoon rainfall(https://sntripathi.in/category/measurements/).

Prof. Tripathi's work on the discoloration of the Taj Mahal exemplifies his proficiency in establishing an interdisciplinary strategy to pin down a compelling cause-effect relationship and reach a firm conclusion.

He played a key role in the development and deployment of one of India's first scientifically validated sensors based air quality monitoring networks in multiple cities.

Prof. SN Tripathi has been the lead Principal Investigator (PI) for a DST-Intel supported project, administered by Indo-US Science and Technology Forum (IUSSTF), titled "SATVAM" (Streaming Analytics over Temporal Variables for Air quality Monitoring).

The SATVAM devices were created with sensor interface circuit boards developed indigenously, low-power data communication technologies, renewable-energy-based autonomous power sources for the monitoring network, and real-time machine learning calibrations as well as spatial and temporal analytics dashboards.

In this work, his team proposed a unique calibration method that could reduce the co-location time of particulate matter (PM) low-cost sensors with a reference monitor.

Prof. Tripathi conducted the first cloud-related experiment in India, which was funded by the Department of Science and Technology's ICRP and the Indian Space Research Organisation's Geosphere Biosphere Program (ISRO GBP).

Prof. Tripathi was Principal Investigator in the international 2008 TIGERZ experiment intense operating period (IOP) in the Indo Gangetic Plain (IGP) around the industrial city of Kanpur, India, during the pre-monsoon conducted in collaboration with the NASA Goddard Space flight Center and Canada.

Prof. Tripathi's vision for lateral translation of knowledge and expertise to serve the crucial cause of academic involvement in nuclear safety investigations is demonstrated by establishing the National Aerosol Facility (NAF) in collaboration with BRNS/BARC, Department of Atomic Energy, India.
