TRMM consists of a several kind of sensors, one of which is CERES (Clouds and the Earth's Radiant Energy System). The objective of CERES is to estimate the earth radiation budget at the top of the atmosphere and the surface, which is depending on the earth-atmosphere activities. The radiation budget of the earth is one of basic parameters for climate research.
The CERES has been designed for this purpose and can give successive products over ERBE. The CERES is not only on the TRMM, but also will be on the other polar orbiters because of its importance of data-succession.
In this report, after a brief history of earth radiation budget research using satellite data, a basic concept of CERES and a flow of retrieval algorithm of radiation budget are introduced, and then an example of preliminary results is shown.
