Bio:

Yohei Shinozuka’s research employs airborne observation of aerosols to reveal their cloud-nucleating and radiative properties and to promote remote sensing and modeling.

Of the known causes of the ongoing climate change one of the most poorly quantified is the atmospheric particles—their interactions with clouds and radiation, to be specific. Their complex and variable nature needs to be better understood and monitored. He performs direct measurements of aerosols from research aircraft with high horizontal, vertical and temporal resolution. His analysis uncovers the properties of the sampled aerosols and supports retrievals and simulations on larger spatiotemporal scales.
