About

Tomi Raatikainen is an atmospheric scientist whose research centers on the radiative impacts of light-absorbing organic aerosols, particularly brown carbon (BrC). His major contribution lies in providing some of the first measurement-based estimates of the direct radiative effect of BrC over the Indo-Gangetic Plain, a critical region for understanding aerosol-climate interactions. By leveraging data from the AErosol RObotic NETwork (AERONET), Raatikainen’s work has helped quantify how brown carbon influences the Earth’s energy balance, moving beyond model-based assumptions to empirical evidence. His most-cited paper (2015) has garnered 34 citations, underscoring its influence in the field. This research is notable for highlighting the previously underestimated warming effect of BrC in South Asia, where biomass burning and urban emissions are prevalent. Raatikainen’s findings are essential for improving climate models and informing policy on air quality and radiative forcing. His work bridges observational data and climate science, making him a key figure in aerosol research. For students and researchers, his studies offer a clear example of how ground-based measurements can unravel the complex role of organic aerosols in regional and global climate change.
