UCLA atmospheric scientist Kuo-Nan Liou has been named recipient of the 2018 Carl-Gustaf Rossby Research Medal for intellectual leadership and seminal contributions to improving the theory and application of atmospheric radiative transfer and its interactions with clouds and aerosols.

The award, which is the highest honor bestowed by the American Meteorological Society, recognizes outstanding individuals and organizations of the weather, water, and climate community. Among his achievements, Liou discovered the depolarization principle to differentiate ice crystals from water droplets and, along with graduate students, developed a unified theory for light scattering by ice crystals and aerosols for application to remote sensing and climate research.

Liou, a distinguished professor of atmospheric and oceanic sciences since 1997 and founding director of UCLA’s Joint Institute for Regional Earth System Science and Engineering will be honored in January at the 98th annual meeting of the American Meteorological Society.
