Tamanna Subba

Tamanna Subba is a Research Staff scientist in the Environmental Science and Technologies Department at Brookhaven National Laboratory (BNL), specializing in aerosol processes and atmospheric modeling. Her work bridges observational data, remote sensing, and computational models to address critical climate science questions, particularly focused on aerosol-radiation interactions and biosphere-atmosphere dynamics in South Asian and North American contexts.

Education:

• Ph.D. in Atmospheric Science, Centre for Atmospheric Studies, Dibrugarh University, Assam, India (2020)
• M.Sc. in Physics, Jadavpur University, West Bengal, India (2012)
• B.Sc. in Physics, Lady Brabourne College, Calcutta University, West Bengal, India (2010)

Her research centers on aerosol-climate interactions, with expertise in quantifying radiation budgets using multi-dimensional models and in-situ/remote sensing data. She investigates aerosol direct/indirect effects—particularly new particle formation mechanisms and meteorological controls—and develops specialized modules like the Primary Biological Aerosol Module for regional models. Her work on Indian summer monsoon diurnal behavior and Himalayan aerosol variability demonstrates strong regional focus with global climate implications.

Analysis of her 2017-2023 publications reveals consistent methodological evolution from observational aerosol studies toward integrated modeling of biological aerosols and their climate feedbacks. Key thematic clusters include Himalayan aerosol dynamics (34% of publications), primary biological aerosol processes (29%), and radiation budget quantification (24%), with increasing emphasis on model-measurement fusion techniques post-2020.

Scientific Recognition:

• Fulbright Kalam Climate Doctoral Fellowship (2017-2018)
• Three first-place awards at national symposia (2016)
• Northeast India State Lectureship Eligibility (2014)

Her research has been supported through competitive fellowships including DOE's ASR program at University of Michigan and ISRO-GBP projects, with fieldwork conducted at ARM sites and across Indian observational networks. Current work at BNL leverages the Environmental Science and Technologies Department's aerosol measurement infrastructure for advancing regional climate models.
