Research Scientist I


Hydrology Applications




Dr. Biswas is a Research Scientist at NOAA Physical Sciences Laboratory (PSL) in Boulder, Colorado and the Cooperative Institute of Research in the Atmosphere (CIRA) at the Colorado State University (CSU) in Fort Collins, Colorado. He is currently working with the Hydrology Applications Division (HAD) in PSL where he is involved in research advancing precipitation estimation and prediction in regions with complex topography focusing on radar- based remote sensing techniques. Before joining as a research scientist, Dr. Biswas worked as a research associate at NOAA PSL while pursuing his Ph.D. at CSU. His present projects include Advanced Quantitative Precipitation Estimation (AQPI), Study of Precipitation, the Lower Atmosphere and Surface for Hydrometeorology (SPLASH), and Surface Atmosphere Integrated Field Laboratory (SAIL). His research interests lie primarily in the areas of radar meteorology, dual-polarization radar systems, satellite remote sensing of clouds and precipitation, data sciences in hydrometeorology, electromagnetics, and digital signal processing. He earned his Bachelor’s degree in Electronics and Communication Engineering from West Bengal University of Technology, India. He earned both his Master's and Ph.D. degrees in Electrical Engineering from Colorado State University in Fort Collins. He is a member of IEEE Geoscience and Remote Sensing Society (GRSS), the American Meteorological Society (AMS), and the American Geophysical Union (AGU).
