Liu Chao-han (simplified Chinese: 刘兆汉; traditional Chinese: 劉兆漢; pinyin: Liú Zhàohàn; born 3 January 1939) is a radio engineer/scientist and an international leader in solar terrestrial physics and remote sensing research.
He started his academic career at the University of Illinois at Urbana-Champaign in 1965 where he taught Electrical Engineering for 25 years.
Shortly after returning to Taiwan in 1990 and based on his earlier research, he proposed and guided the implementation of the Constellation Observation System for Meteorology Ionosphere & Climate, FORMOSAT III/COSMIC, in collaboration with University Corporation for Atmospheric Research (UCAR) and the Jet Propulsion Laboratory (JPL) in the United States.
From 2006 to 2020, the data collected by this system enabled the drastic improvement in the daily weather forecast.
