About

Dr. Prakash Chauhan is a distinguished Earth observation scientist whose research focuses on atmospheric aerosol retrieval, satellite remote sensing, and climate dynamics over the Indian subcontinent and surrounding oceans. His most significant contribution lies in pioneering the operational retrieval of aerosol optical depth (AOD) from geostationary satellite data, specifically using the INSAT-3D Imager. His landmark 2014 paper, which has garnered 7 citations, introduced a single visible channel algorithm based on clear-sky composites to derive AOD at 0.65 μm wavelength over the Indian subcontinent and Indian Ocean region—a first for geostationary earth orbit satellites. This work has been instrumental in enabling real-time monitoring of aerosol loading, crucial for understanding regional climate forcing, air quality, and monsoon dynamics. Dr. Chauhan’s research bridges the gap between satellite technology and environmental applications, providing high-temporal-resolution data that supports both scientific inquiry and policy-making. His contributions have advanced the field of atmospheric remote sensing, offering a robust framework for aerosol studies in data-sparse tropical regions. Through his innovative algorithms and operational products, Dr. Chauhan continues to shape our understanding of aerosol impacts on weather and climate.
