The EMS Young Scientist Award 2020 will be presented to Velle Toll, University of Tartu, Estonia, nominated with the publication: “Weak average liquid-cloud-water response to anthropogenic aerosols”, V. Toll, M. Christensen, J. Quaas, N. Bellouin, Nature (2019), https://doi.org/10.1038/s41586-019-1423-9.
Velle Toll receives the award for his work that significantly improved the understanding of the anthropogenic air pollution particles, clouds and climate. The findings rely on a novel analysis of the properties of polluted clouds downwind of variety of anthropogenic air pollution sources using MODIS satellite data. These findings invalidate the hypothesis that increases in cloud water cause a substantial climate cooling effect and translate into reduced uncertainty in projections of future climate.
Velle Toll’s field of primary research covers aerosol climate forcing, aerosol-cloud interactions, atmospheric remote sensing and climate change.
Velle Toll received his PhD in Atmospheric Physics in 2016 from the University of Tartu, Estonia. His thesis topic was “Direct radiative impacts of atmospheric aerosols on meteorological conditions over Europe”.
From 2012 to 2015 he was a research assistant at the University of Tartu, Institute of Physics, Department of Atmospheric Physics, and working for the Estonian Environment Agency, Department of Numerical Modelling as a NWP model developer. After two years at the Department of Meteorology at the University of Reading doing postdoctoral climate research, he returned to the Department of Atmospheric Physics at the University of Tartu as a researcher. He has also been teaching various subjects in atmospheric sciences at the University of Tartu since 2015.
