Research on development of a system to monitor the earth's radiation budget and investigation of related effects on climate change

The characteristics of the earth’s climate are determined by its radiation budget Ea term describing the balance of incoming solar radiation and outgoing terrestrial infrared radiation. This metric is therefore an important factor in the earth’s climate system. The radiation budget is affected by aerosols, clouds and various other substances, as well as by atmospheric trace gases such as carbon dioxide and water vapor. The long-term trend of the earth’s radiation budget causes climate change manifested by phenomena such as global warming. However, understanding of the mechanism behind the radiation budget remains insufficient, and this is considered to be one of the main reasons for the uncertainty of global warming prediction. In this study, the effects of these substances on the earth’s radiation budget will be investigated using ground-based observation data, aircraft observation data and satellite data with numerical models of radiative transfer.


Various radiation components are measured synthetically to investigate the relationship between the surface radiation budget and the radiative properties of clouds and aerosols
