Dr. AKSHAY KUMAR SAGAR

About

P.Scientist II at the National Center for Medium Range Weather Forecasting (NCMRWF), specializing in renewable energy, tropical cyclones, extreme weather events, and machine learning applications in atmospheric science. With over nine years of experience in satellite data analysis and AI-driven climate modeling, my work focuses on renewable energy, cyclone genesis, Accumulated Cyclone Energy (ACE), air pollution, greenhouse gases, and the climatic impacts of solar geoengineering across the Indian subcontinent.
My research integrates causal inference, deep learning, and geospatial analytics to uncover robust precursor regions for cyclonic activity and long-term climate variability. I have extensive experience with Python, ArcGIS, MATLAB, and advanced data science libraries, including Scikit-learn, PyTorch, and Google Earth Engine. My technical expertise spans trajectory modeling (HySPLIT), radar data analysis (wradlib), and handling large-scale satellite datasets.
Authored 13 peer-reviewed publications and book chapters on topics such as greenhouse gas trends, monsoon dynamics, and climate mitigation strategies. My interdisciplinary approach bridges Earth system science, statistical modeling, and AI to advance understanding of climate extremes in South Asia and beyond.
