Preface to the Special Issue on Fengyun Meteorological Satellites: Data, Application and Assessment

Humans have a more than sixty-year history of observing Earth from space beginning after the launch of the first meteor-ological satellite,Television Infrared Observation Satellite(TIROS),in 1960.Satellite observations have transformed the way scientists observe and study Earth(Ackerman et al.,2019).With the progress of satellite data assimilation in the 1990s,modern Numerical Weather Prediction(NWP)became deeply tied to global satellite observations(Eyre et al.,1993).Scient-ists expect that meteorological satellites will play a more important role in future Earth Science studies.
