D. Bala Subrahamanyam is an Indian space and atmospheric scientist working at the Space Physics Laboratory of the Vikram Sarabhai Space Centre, which is part of the Indian Space Research Organisation. He serves as a Scientist/Engineer “SG” and heads the Numerical Atmosphere Modelling (NAM) Branch at the laboratory. His research primarily focuses on atmospheric science and space-related environmental studies, including boundary-layer meteorology, regional atmospheric modelling, numerical weather prediction, air–sea interaction processes, data assimilation, and the use of artificial intelligence and machine learning in atmospheric research. Dr. Subrahamanyam obtained his Ph.D. in Physics from Mahatma Gandhi University, Kottayam, with research on the marine atmospheric boundary layer over the tropical Indian Ocean. Over the years, he has contributed to several national and international research programs related to atmospheric observations, ocean–atmosphere interaction, and weather prediction. Before joining ISRO’s Space Physics Laboratory as a scientist, he worked as a research fellow and research associate at the same institute and also served as a project scientist at the Indian National Centre for Ocean Information Services. His work supports the scientific understanding of atmospheric processes relevant to space and Earth system science.
