| Outline of Final Research Achievements |
In order to capture the spatial and temporal variations of the upper clouds, which play important roles in determining the radiation balance of the earth, we have developed methods to retrieve the upper cloud properties from the satellite data. Variations of cloud amount and optical and microphysical properties were investigated. In the tropics, distribution of the optically thick upper cloud is well associated with areas of high convective activity. The distribution of the cirrus cloud spreads to the higher latitudes than that of the convective cloud, and the cirrus cloud distribution also fluctuated corresponding to the seasonal cycle of the convective activity. The interannual variation of the upper cloud is closely related to the ENSO. In addition, we developed a cloud analysis algorithm using the Himawari-8 data, and it became possible to capture the temporal variation of clouds with frequent observation of the Himawari-8.
