Dusty Cloud Radiative Forcing Derived From Satellite Data For Middle Latitude Regions Of East Asia.

The radiative forcings by aerosol and cloud are recognized as the two important contributors for climate change . However, the effect of the radiative forcings by aerosol and cloud on climate have not well understand due to the complexity of the radiative forcings by aerosol and cloud and the complicated cloud-aerosol interaction,, as well as the limited observation and the lack of datas. As one of the main categories of aerosol, the sand dust has important influences on the regional and global entironment and climate. It not only reflects the incoming solar radiation to space, but also can modify cloud properties by changing the number concentration of cloud droplets, which alters both cloud optical depth and cloud lifetime. In addition, it can affect the radiative heating structure of the atmosphere, thereby changing the clouds and atmospheric circulation. Despite the fact that the Taklamakan and Gobi Deserts are major sources of dust aerosols ,there have been few studies focusing on the effect of Asian dust aerosols on cloud,especially ice cloud, properties and radiative forcing. This thesis investigates the influence of Asia dust on ice cloud properties and radiative forcing.In this thesis, the most recent data of Clouds and the Earth's Radiant Energy System (CERES)Single Scanner Footprint (SSF) Aqua...
